How to Remove a Spline Nut on a 1999 Oldsmobile Alero

The spline nut, also known as the axle spline nut or axle nut, is located on the threaded end of each front axle shaft. This nut holds the splined end of the axle securely inside the wheel hub. The axle nut is a 34 mm nut that is pinched in order to prevent it from loosening. Because the nut is pinched in the manufacturing process, it is not reusable. There are two types of axle nuts installed on 1999 Aleros, and both are not reusable. The first type is the older style that is black with a sheet metal cage around the nut. The new nut is a silver-colored, standard-size pinch nut. If your vehicle has the old style nut, it must be removed and replaced with the new style nut. If your vehicle has the new style nut, it must be replaced when removed with a new nut of the same style.

Instructions

Removal

    1

    Apply the parking brake and chock the rear wheels. Break the front lug nuts loose with a lug nut wrench. Raise the vehicle with a jack and slide jack stands under the frame. Lower the vehicle onto the jack stands and make sure that its secure.

    2

    Remove the lug nuts completely, then remove the tire. Have an assistant depress the brake pedal. Attach a 34 mm socket to a T-handle bar and break the axle nut loose while your assistant is holding the brake pedal; this will prevent the wheel and hub from turning while you break the nut loose.

    3

    Remove the axle nut the rest of the way using a 1/2-inch ratchet and your 34 mm socket. Throw away the old nut; it cannot be reused.

Installation

    4

    Thread the new nut onto the spindle by hand, then have an assistant depress the brake pedal once again.

    5

    Tighten the nut to 173 foot-pounds with a torque wrench. Reinstall the tire and snug the lug nuts with a lug nut wrench.

    6

    Lower the Alero back to the ground and torque the lug nuts in a criss-cross pattern to 100 foot-pounds with a torque wrench.

Can You Pull off Spark Plug Wires While the Engine Is Running

Like most ponderings in automotive repair, the question of removing spark plug wires from a running engine isnt necessarily so much one of "could" as it is of "should." Technically, yes, you can yank the plug wires off of a running engine just as easily as you could one that isnt running, but it may not necessarily prove conducive to you or your cars good health.

You Could

    Removing a plug wire from a running engine isnt likely to result in catastrophic engine failure, particularly if you put it back on shortly afterward. All spark plugs misfire from time to time, you just dont notice it because its intermittent, random and usually happens so quickly that the cylinders firing again before the engine has a chance to vibrate. So, intentionally creating a misfire by removing the plug wire for a few seconds or even a few minutes isnt likely to destroy anything on most engines.

Common Effects on the Engine

    Most engines have a rubber ring on the front of the crankshaft called a harmonic balancer; on the outer edge of the balancer is a heavy, metal ring. When the explosions in the engines cylinders push down on the pistons, the forces they exert quickly accelerate the crankshaft. When that accelerations over, the crank tries to slow down, resulting in a constant cycle of acceleration and deceleration that manifests as vibration in the crankshaft. The metal ring on the balancer resists these sudden, but tiny, vibrations and keep the crank from tearing itself in two. Over a long enough period of time, a dead cylinder and the resultant heavy vibration will over-work the balancer, causing it to fail. Once that happens, you could be looking at serious damage to the engine.

Effects on the Converter

    Your cars catalytic converter works something like a blast furnace to convert toxic gases produced by your engine into more inert forms that wont drown polar bears or grow fish with three eyes. The converter takes advantage of unburned fuel -- which is, itself, a pollutant -- coming from your engine and uses it to fuel the furnace in the converter matrix. More fuel means more heat. Killing the spark in one cylinder will drastically increase the amount of fuel pouring into your exhaust, which will, at some point, cause the converter to overheat and fail. The engines control computer will compensate for this to some extent, but you can count on extra fuel going into the exhaust.

Lean-Out

    Depending upon the computers control strategy, disconnecting a plug wire and leaving it that way could seriously fry something. When the oxygen sensor detects excess fuel in the exhaust, your cars computer may assume that this represents a net excess of fuel through all the cylinders. It will respond by decreasing the amount of fuel injected to all of the other cylinders in order to get the air/fuel ratio back in line. The resulting lean condition will increase combustion chamber temperature, causing overheating, detonation in the engine and, eventually, complete meltdown. Most computers do have programming provisions to account for a dead cylinder, and wont react this way; but some dont, and theres no way to be sure unless you know exactly how your fuel injection system thinks.

Safety Issues

    Before pulling the plug wire off of a running engine, bear in mind that your are, in fact, grabbing a live wire with about 40,000 volts worth of electricity coursing through it. Normally, this electricity will pass through the plug wire and race to the spark plug, which acts as a ground. But when you remove that ground, the spark is going to find the next, most convenient ground. If you happen to be touching the body of the car when you pull the wire off, then you become that ground. While electricity normally wouldnt arc through the insulation, even if it is a bit old and damaged, removing the primary ground will make that spark pretty determined to get out whatever way it can. Its not likely to kill you unless you have heart or nervous system problems, since the amperage is very low -- but the sensation is rather, shall we say, "life affirming."

How to Tell If Your Fuel Pump Is Broken

How to Tell If Your Fuel Pump Is Broken?

The fuel pump is an essential component of a vehicle. Fuel is pumped from the fuel tank to the engine. Without a functioning fuel pump, adequate fuel pressure cannot be delivered to the engine. This will cause problems such as hard starting, rough idle, misfiring, hesitation and stalling and can even prevent the car from starting . This may happen at the most inconvenient time. If you suspect that your fuel pump is broken, there are certain tests that you can perform to confirm it.

Instructions

    1

    Listen for a humming sound that normally occurs when the key is turned to the "Start" position. Turn the key in the ignition to the "Start" position and listen for a humming sound from the fuel tank. A hum means that the pump is in working condition.

    2

    Check if your fuel pump is broken by doing a static fuel test. Turn the key in the ignition to the "on" position. Look at the fuel pressure gauge to detect movements. The fuel pressure should immediately come up and stay steady. If it doesnt, that can indicate that there is a defect in the fuel pump.

    3

    Connect a voltage meter to the wires that connect to your fuel pump. Connect the voltage meter to the green wire. The fuel pump wires are located under the vehicle, behind the drivers door. Let someone start the engine while the voltage meter is connected to the wire. A normal reading is between 10 to 11 volts. If there is a zero reading, this usually mean that the fuel pump is bad.

How to Replace an Exhaust Catalytic Converter

The catalytic converter happens to be one of the most expensive parts of a car to fix, which leads many people to try to repair it at home. You have to know your way around cars and exhaust systems, or youre honestly better off taking it to a mechanic. If youre comfortable working on it yourself, there are a few things you should keep in mind.

Instructions

    1

    Lift your car. Unfortunately, the catalytic converter sits about midway down the length of your car, so lifting one end or the other will not do. Ramps are your best bet to get you within reach of the parts when working from home. Luckily, this is usually the hardest part of this repair.

    2

    Be patient with the bolts, as they are often hard to remove due to size and awkward placement. You may have to drill or saw bolts to remove them. With this in mind, you should pick up new bolts, nuts and seals for your replacement project.

    3

    Buy a catalytic converter specific to your car to avoid extra work. A generic part must be welded into the car, while a vehicle-specific model comes pre-welded to the proper pipes for easy bolt-on installation.

    4

    Remove the 02 sensor (with an O2 wrench) before unbolting the catalytic converter. Then, you should remove the pipe connecting the sensor to the converter. Depending on your exhaust system, you may have to remove more pipes before you unbolt the converter from the muffler.

    5

    Replace the old catalytic converter with a new one. This should be the easy part, as you simply bolt the new part in place.

    6

    Reattach the exhaust pipes and 02 sensor, and the basic job is done. Make sure you replace any cracked or rusty pipes while you have the exhaust system apart.

How to Balance Synchronize Motorcycle Carburetors

How to Balance & Synchronize Motorcycle Carburetors

Many motorcycles have multiple carburetors providing power for the engine. In a multiple carburetor system, one or more carburetors may fall out of adjustment, or synchronization, with the others. This causes the cylinder to receive a different amount of air and fuel than the others and create an imbalance in the engine. Poor power, hesitation and bad fuel economy may result. You can make a mechanical adjustment to ensure all carburetors work at the same time and same rate.

Instructions

    1

    Place the motorcycle on the center stand. Start the engine and allow it to warm up until it idles reliably. Do not allow it to reach full operating temperature as this may lead to overheating.

    2

    Shut the engine off. Turn off the fuel supply petcock at the gas tank and remove the fuel line at the carburetors. Remove the hold-down bolt at the rear of the gas tank and lift the tank off the motorcycle. On some models, it may be necessary to remove the seat or side covers in order to remove the gas tank and access the carburetors.

    3

    Remove the vacuum plugs from the carburetor bodies. Some motorcycles have rubber caps press-fit into vacuum ports; others have screw-in plugs that require adapters that come with a multi-port manometer kit. Select the proper adapters and connect the vacuum lines from the synchronization tool to the ports on the carburetor bodies. On motorcycles with more than two carburetors, match the numbers on the manometer ports to those on the carburetor.

    4

    Hang the auxiliary gas tank from the handlebars and connect the hose to the carburetor gas line inlet. Place the portable fan in front of the engine and direct the air flow over the engine to keep it cool. Turn the auxiliary gas tank cut-off valve to the "On" position. Ensure the fuel hose is not touching against an exhaust pipe or the engine.

    5

    Start the motorcycle and observe the readings on the synchronization tool. The carburetors must be adjusted if the gauge reads more than 2.4 inches of mercury between any two or more units. Locate the adjusting screws for the carburetors. Some models have the screws located between the carburetor bodies; other models require the removal of a top cover to access the adjusters.

    6

    Identify the base carburetor. On any multi-carb system, one carburetor is considered the base piece and is not adjustable. All other carburetors can be adjusted to match the base piece. The base carburetor is normally identified by having the throttle cable and idle speed screw attached to it. Turn the adjusting screws on the other carburetors one at a time until the readings on the synchronizer are within 2.4 inches of each other. Tighten down any lock-nuts, making sure the adjustments do not change.

    7

    Repeat the previous step for every carburetor on the motorcycle. Open and close the throttle a few times and recheck the readings. When all readings on all carburetors are within 2.4 inches, tighten all lock-nuts and replace any covers or other devices that were removed to access the adjuster nuts. Set the final idle speed to the manufacturers specifications and shut down the engine.

    8

    Remove the auxiliary gas tank and synchronization tool . Remove any adapters and replace the vacuum port plugs or caps on the carburetors. Replace the gas tank, side covers or any other component that you removed.

Types of Carburetor Chokes

Over the years, various models of carburetor chokes have been developed in order to facilitate different engine conventionalities such as differing engine designs, varying load requirements and air/fuel intake varieties. In essence, the varieties of carburetors have been specifically designed to provide an assortment of drafting amounts, a multitude of barrels and varying venturi and flow rates.

Carburetor Draft

    The variation in draft technology is one way in which carburetor chokes can be classified. Drafting within carburetors can be defined as sucking in or exhaling out air. There are three main types of drafting technologies that can be incorporated into carburetors. These are downdraft, sidedraft and updraft models. The downdraft and updraft technologies work using a method completely opposite to each other. Downdraft allows air to flow through the engine in a downward direction whereas the updraft variety allows air to be transferred through the engine in an upward direction. On the other hand, the sidedraft variety allows air to flow through the engine in a horizontal manner. Sidedraft technology was incorporated into older vehicle models whereas downdraft technology is used in cars these days. However, updraft carburetors are used in machinery such as forklifts.

Carburetor Barrels

    Carburetor barrels can basically be defined as a hollow cylinder in which air and fuel is mixed by the engine. The basic parts are the throttle plate, air horn and venturi. There are three essential types of carburetor barrel models; one-barrel, two-barrel and four-barrel carburetors. The one barrel model is primarily incorporated into small engines that do not require a lot of power such as a motorcycle. On the other hand, a two-barrel system is used in cars with large engines and comprises two throttle plates and double venturis. A four-barrel model is used with trucks and SUVs because it has the ability to provide a large amount of engine force. Under normal conditions, the engine uses only two of the four barrels. If extra power is required, the other two barrels are employed to mix in more fuel and air.

Feedback Carburetor System

    In accordance with technological breakthrough of todays day and age, car makers have developed an electronic carburetor system that has the ability to provide highly efficient energy by electronically maintaining the levels of air and fuel. The electronic carburetor is used in almost all of the cars being built today and also has the ability to reduce pollution by oxidizing HC and CO as well as reducing the amount of nitrogen oxide expelled into the air. The entire system uses a three-way catalytic converter which maintains the most efficient mixture of air (oxygen) and fuel.

How to Thread a Shift Rod

How to Thread a Shift Rod

Shift rods are used in cars, trucks and motorcycles that have manual transmissions. A shift rod consists of two eye-bolts that are threaded onto a steel rod. As you change gears, the shift rod engages and disengages the clutch linkage. Shift rods are available in various lengths from auto parts stores, or you can have one cut to a custom length to fit your particular application. A die set may be used to cut threads on a blank or universal shift rod when the original is not available.

Instructions

    1

    Place the shift rod in a bench vise and secure it firmly. If the rod is chrome, place a shop towel around the shift rod before you tighten the vise to keep the rod from being scuffed.

    2

    Measure the internal threads of the eye-bolts with the thread gauge. The gauge will have a mark on its side to show which size thread will need to be cut.

    3

    Select the correct size die and install it in the die wrench. Secure the die by tightening the two screws in the wrench to hold it in place.

    4

    Apply cutting fluid to the area that is being threaded. Place the die wrench on top, perpendicular to the shift rod. Turn the wrench clockwise while pushing down. For every full turn, back the wrench off one-half turn to remove burrs. Continue to turn the wrench until you have cut the thread the desired length.

    5

    Remove metal shavings and excess cutting oil from the shift rod with a shop towel. If cutting both ends of the shift rod, remove it from the vise and turn it over. Repeat Steps 1 through 4.

How to Install a Belt on a 2000 Windstar

In 1995, Ford launched the Windstar in an attempt to pull some customers away from the overly successful Chrysler minivans -- the Chrysler Town & Country and Dodge Caravan. The 2000 Windstar had two V-6 engines available: a 200-horsepower 3.8-liter and a 150-horsepower 3.0-liter. In my years in repair shops, I have replaced the serpentine belt on numerous Windstar vans and have found that is is just like any other vehicle, with exception of a few details.

Replacing Serpentine Belt

    When I replaced the belts on various 2000 Ford Windstars, I found that the tensioner pulley on the 3.0-liter V-6 engine just below the alternator pulley, and on the 3.8-liter V-6 engines, next to the power steering pump pulley. Because of limited clearance, I always used a 15 mm box-end wrench to rotate the tensioner, as a socket takes up a little too much working space.

1996 Mustang Alignment Specs

1996 Mustang Alignment Specs

Ford introduced the Mustang in 1964 to compete with Chevrolets Corvette. The Mustang quickly became one of the most popular muscle cars ever made and went on to become an American icon. The Mustang has changed dramatically since those early years, in terms of both its appearance and its performance, but it is still one of most popular sports cars on the market.



The Mustang was redesigned in 1994 and kept that body style until it went through another major redesign in 1999, taking on a boxier, more aggressive style than the rounded-off body of the 1994 to 1998 models. In 1996, Ford put a new Borg-Warner T-45 Transmission in the Mustang, as well as a new 4.6-liter, modular engine, which is still used in the Mustang today.

General Alignment Information for the 1996 Ford Mustang

    The front end of 1996 Ford Mustang has a modified McPherson strut-design with shock struts and coil springs. The rear end has a solid-axle design, and its alignment cannot be adjusted. Problems with the alignment on the rear end are more likely due to bent or damaged parts.

    The front-end alignment specs are the same for all trims of the 1996 Mustang. (Reference 4)

    Always consult an owners manual or a certified mechanic before attempting to perform your own automotive repairs.

Caster Angle

    The limits for the caster angle for the front wheels of the 1996 Ford Mustang range from +2.65 to +4.15, with the ideal angle being +3.4 degrees.

How to Check a Civic for VTEC E

The VTEC-E is the single overhead-cam version of the Honda Civic VTEC engine, designed to increase fuel economy at low rpm. Only one of the two intake valves opens a very small amount at low rpm, increasing the fuel/air atomization in the cylinder, utilizing a leaner mixture. It is necessary for the technician to know if the Civic is equipped with a VTEC or a VTEC-E model engine when attempting to diagnose a problem. Identifying a VTEC-E requires little more than raising the hood and making a phone call.

Instructions

    1

    Pull the inside hood release, and lift the hood of the Honda Civic.

    2

    Find the engine model number engraving located toward the front of the engine just below the head gasket. Remove any grease or dirt that covers the engraving.

    3

    Read and record the engraving.

    4

    Contact the service department at a Honda dealer and ask a service representative to decode the engraved number to determine if the engine is a VETEC-E.

Ford Windstar Fueling Problems

Ford Windstar Fueling Problems

Ford Windstar fueling problems have resulted in several recalls on models manufactured between 1995 and 2003. Fuel system defects, including incorrectly manufacturer parts and cracks in the gas tank, can result in potentially dangerous gas leaks. The National Highway Traffic Safety Administration (NHTSA) advises that registered vehicle owners take affected vehicles in for repair to avoid accidents and injuries. Registered vehicle owners should have been notified of recalls via mail by Ford Motor Company.

1999-2003 Models Recalled for UFI Filter Defect

    As part of a 58,640 unit recall by UFI Filters USA and NHTSA, certain 1999-2003 model Ford Windstars were recalled in August 2006 due to design defects that could potentially cause fuel spillage and fires. According to NHTSA, the recall only applies to certain defective filters sold under the Purolator brand name "P/N F65277" that were shipped from Jan. 16 through June 2, 2006. Due to the design defect, "the quick connectors might not fully seat with the tube interface, even though the person making the connection may believe that the quick connector is fully attached," the recall notice states. This may lead to dangerous gas leakage problems, which could cause a fire.

2000 Models Recalled for Incorrect Fuel Line End Forms

    On June 14, 2000, Ford Motor Company recalled 3,000 Windstar minivans because these vehicles may have incorrect fuel line end forms that could result in a lower than specified pull-apart force for the installed fuel line connection. This problem may result in gas leakage, which could lead to a fire. To remedy the problem, dealers must "install a redundant fuel line clip on the fuel supply and return line connections at the rear of the chassis fuel line bundle," the recall notice states.

1995 Models Recalled for Fuel Tank Cracks

    In November 2009, Ford Motor Company recalled 70,116 Windstar minivans manufactured in 1995 due to fuel tank cracking problems in hot-weather states. This particular model can develop fuel tank cracks in the strap area of the standard 20 gallon tank due to "a combination of factors that are present in certain very hot areas of the country." If cracks propagate all the way through the fuel tank, a potentially dangerous gas leak may result. This recall was issued for registered vehicle owners in Alabama, Arizona, Arkansas, Florida, Georgia, Hawaii, Louisiana, Mississippi, Oklahoma, South Carolina, Texas, Nevadas Clark County and 10 southern counties of California.

How to Repair Clear Coat Bubbles

How to Repair Clear Coat Bubbles

It can be disheartening when repainting your automobile to see bubbles in your final stage of applying the clear coat. After all the work you put into sanding, primer and paint, it is all too easy to see your labor marred by these tiny bubbles, also known as fish eyes. These can be caused by a variety of things, including tiny bits of oil, water or dirt. Even passing diesel exhaust fumes can cause fish eyes in your clear coat. You can repair them, but it is a time-consuming process.

Instructions

    1

    Wet sand the bubbled portion of your automobiles surface using extra-fine sandpaper and water. You must sand away all of the clear coat on the affected portion. For example, if there are bubbles on the hood of your car, you must sand the entire hood, not just the bubbles. Always keep your sanding area wet, and gently sand away the clear coat. Do not sand too hard, or you may remove the paint.

    2

    Wash and rinse the sanded areas of your automobile thoroughly to completely remove all debris from the surface. If there is any debris remaining, fish eyes will form again when you reapply the clear coat. Allow the surface to completely dry since water can also cause bubbling in the clear coat.

    3

    Mix fish eye preventer and clear coat in your paint sprayer according to the fish eye preventers instructions. The preventer is silicon-based, and can compensate for tiny bits of oils or debris in the atmosphere that could potentially cause fish eyes.

    4

    Spray the clear coat and fish eye preventer mixture on the affected portion of your automobile. Use a smooth, even motion. If you plan to apply more than one coat, make sure that the preceding coat is completely dry. If the preceding coat is still wet, this could also cause bubbles to form.

Snap on Wrench Automotive Tools

Snap on Wrench Automotive Tools

Snap-on Tools has long been an understood mainstay supplier of professional mechanic garages, given the companys wide array of tool choices. From hundreds of hand tools to pneumatic and automated ones, the company consistently produces a quality product. This is important since much of the work mechanics perform regularly would break home tools quickly. Manufactured for significant harder work pressure than normally expected with consumer grade tools, Snap-on instruments for automotive work have been available for 90 years, with ratchets, sockets, wrenches and screwdrivers making up the basic bread-and-butter of the choices.

History

    Snap-on automotive tools, along with its general product line, first came on the market in the early 1920s. The initial product line focused on basic wrenches with interchangeable sockets. Prior to this time, tools did not have such flexibility, and what you bought only worked in terms of one function and one size. As a result, a mechanic typically needed a lot of molded tools for different work sizes. Using the door-to-door salesman approach, Snap-on was an early innovater visiting mechanic shops and showing their tool product value on the floor. This immediatey created a growing boom driven by eager customers.

Todays Automotive Tools

    Snap-on tools today still delivers via a stocked dealer van just the way they were beginning in the 1950s. Again, the emphasis is on instant proof of the tools value on the shop floor. Tools today include hand versions, diagnostic measurement units, and power or automated tools (electric and pneumatic). Snap-on has also branched out its tool line into software and vehicle repair database management.

Hand Tools

    The hand tools still resemble the basic categories of the 1920s: screwdrivers, wrenches and sockets. In addition, Snap-on also provides a wide line of automotive-specific tools such as specialty tools, punch and chisels, specialized hammers, big and small crowbars, and plenty of versions of pliers for a wide range of jobs. For engine work, Snap-on provides a wide line of bearing and oil seal installation and removal sets, piston work tools, bushing and suspension-specific tools, and specialty lathes and cutting tools for fabrication.

Power Tools

    Snap-on power tools come in two categories: electric and pneumatic. These units tend to be for heavy duty work and high-powered applications. The selection includes impact wrenches, air drills, pneumatic ratchets, hammer tools and many types of fabrication tools (grinders, cutters, polishing, and hammering).

Automotive Tool Storage

    With the wide array of tools to choose from, mechanics will quickly find a need for storage to make sure tools are secure and dont get lost. Snap-ons selections provide for storage units ranging from rolling drawers to full-size closet storage, all being lockable as needed. More importantly, the storage units are stronger than retail grade, so they dont buckle under the tool weight.

What Happens When Water Is Put Into a Cars Gas Tank

What Happens When Water Is Put Into a Cars Gas Tank?

Water and fuel dont mix, so its never a good idea to put water into a cars gas tank. However, when water does get into a gas tank, either accidentally, or as the result of a malicious prank, the result is engine trouble.

Condensation

    Water can get into a gas tank even if you didnt put it there. Sometimes water gets in through a badly sealed cap on the tank, or by natural condensation on the inside of the gas tank

Problems

    Water in the gas tank may lead to the car bucking, stalling or not starting at all, or starting the car could be difficult. This is because the water and fuel separate, especially when the car has been sitting for a while, and the water sinks to the bottom with the fuel on top. Water can also get into other parts of the engine causing rust and corrosion.

Removal

    The method you use to get rid of water in your cars gas tank depends on how much got in there in the first place. In the case of only a little water, an additive that dries up water could be used. The additive combines with the water as it goes through the running engine. If there is a lot of water, a mechanic will have to remove the gas. This may include removing the fuel tank from the car and putting in new filters. The tank is then put back and is filled with clean gas.

How to Repair Bottle Jacks

How to Repair Bottle Jacks

A bottle jack is an essential tool for any mechanic. When you need to raise a vehicle, nothing will do a better job than a bottle jack. When your jack fails, it can leave you completely unable to work on a vehicle. Instead of sending yours away for a lengthy and costly repair, check some of the common causes of problems with bottle jacks. You may find you can repair the problem before sending your jack away.

Instructions

    1

    Check the weight limit of your jack and compare if with the weight of the vehicle. The capacity of the jack is written either on the jack or the documentation that accompanied it when it was new. The weight of a car is usually written on a panel on the drivers door pillar. Do not lift a vehicle with a jack or rated to handle the weight. Property damage or injury could result.

    2

    Remove the jack from the vehicle and extend it all the way out. You may be able to do this by pumping with no weight or you may have to open the release valve and pull the piston out. Watch for binding in the piston as you are pulling it out, also check for excessive oil (there should be a little, but not much more), dirt or other foreign substances on the piston. These could be a result of a bad seal. Examine the seal around the bottom of the piston for damage. If this seal is damaged the jack will likely need to go to a repair shop.

    3

    Open the oil reservoir filler cap and check the level of the hydraulic oil. This cap is usually the uppermost cap on the bottle jack and you may need the screwdriver to help you open it. The oil should be about 1/4-inch below the level of the hole. If the oil is low then add hydraulic fluid to bring it to the right level but do not over fill.

    4

    Bleed the jack by opening the release valve and pumping the handle vigorously several times. Close the release valve and pump the jack up to its full height. If it still wont go all the way up then repeat the bleed process until it does. Wipe the jack with the cloth before bleeding and then examine it afterward for any sign of a leak. If you find a leak then trace it back to the seal it is coming from and replace that seal. The procedure will vary depending on the seal and the model of jack. Consult a professional if you are unable to replace it.

    5

    Lift the vehicle using the jack. If the jack still will not lift then you may have a problem with the pump. This is a very complex system and you should send the jack to an authorized repair facility to have the pump replaced.

How to Cut a Gas Tank in Half

Cutting a gas tank in half isnt an overly difficult task if youre equipped with the right tools. Although you could use a grinder or oxyacetylene torch to accomplish the job, the safest and perhaps most efficient tool to use is a reciprocating saw. In order to cut the tank effectively, the saw will need to be fixed with a metal-cutting blade. A metal-cutting blade will utilize multiple teeth, usually numbering somewhere between 14 and 20 per inch. This is much more than a wood-cutting blade, which has only 6 to 8 teeth per inch.

Instructions

    1

    Rinse the gas tank out several times with water and let it drain. If you have time, you should also allow the tank to air out for roughly 3 to 5 days. Obviously, the gas should be removed from the vehicle.

    2

    Use marking chalk to draw a line around the middle of the gas tank. By following this line, youll be better equipped to make a clean, straight cut around the entire gas tank.

    3

    Attach a bit to your drill specifically designed for drilling in metal. Put on your safety glasses and drill a hole at some point along the line you drew with the marking chalk. The hole you drill will make it easier to insert the blade and start the cut with your reciprocating saw.

    4

    Grip the reciprocating saw firmly and pull the trigger to start the saw. Start the blade into the hole you drilled and begin sawing the gas tank in half. Follow your line and work slowly. If you rush or push too hard, you may dull or damage the saw blade. Continue cutting until youve successfully separated the gas tank into halves.

How to Remove a Head From an F 250

The Ford "F" series of full-size pickups use the model number to indicate the rated carrying capacity of the vehicle. For example, an F-250 has a payload capacity of about 2500 pounds, and newer models can carry more than this. The standard engine options for the F-250 include 5.4-liter and 6.8-liter gasoline engines. These engines have two cylinder heads, each covering half of the cylinders. The procedure for removing the cylinder heads is generally the same for all F-250 trucks made since 2001 with gasoline engines.

Instructions

    1

    Remove the air conditioner from the vehicle to access the cylinder heads on top of the engine block. This generally requires a professional mechanic with special equipment to avoid releasing rigerant gas into the atmosphere.

    2

    Disconnect the cable from the negative battery terminal with a socket wrench to ensure the engine does not start accidentally. Remove the covers for the cylinder heads.

    3

    Remove the intake manifold from the engine block with a socket wrench. Disconnect the timing chains from their sprockets. Remove the exhaust manifolds from the engine.

    4

    Disconnect the two retaining bolts for the heater hose with a socket wrench. Squeeze the clamp together, and slide it down the hose to release the hose. Detach the heater hose from the engine block. Remove all additional electrical connectors and hoses needed to access the cylinder heads in your F250.

    5

How to Replace an Oxygen Sensor in a Wrangler

How to Replace an Oxygen Sensor in a Wrangler

If the check engine light on the dash of your Jeep is on, stop into an auto parts store and ask them to scan your Jeep for codes. Nearly all major auto parts store offer this service for free. Failure of the oxygen sensor is a common problem, but the part can be changed at home, saving you a major repair bill. The oxygen sensors are in the exhaust pipe between the engine and the catalytic converter on the Jeep Wrangler. You will need a special socket to remove the oxygen sensor, available at most auto parts stores and tool supply stores.

Instructions

    1

    Lift the Jeep with a jack and support it on all four corners with a set of jack stands. The oxygen or O2 sensors are in the exhaust under the middle of the Jeep, so you will have to lift the entire Jeep to access them effectively.

    2

    Locate the two O2 sensors in the exhaust system. The first one is near the center of the transmission, and the second is between the resonator and the catalytic converter. Unplug the wiring harness connectors from both sensors by lifting the locking tab with a small flat screwdriver and pulling them from the harness.

    3

    Remove the O2 sensors, one at a time, using a oxygen sensor socket and a ratchet. Turn the sensor counter-clockwise to remove it from the exhaust. Discard the old sensor.

    4

    Install the two new sensors into the threaded sections of the exhaust where you removed the old ones from. The two sensors used by Jeep are identical, so either one is fine in each hole.

    5

    Tighten the sensors with an oxygen sensor socket and a torque wrench to 22 foot-pounds. Do not use thread locker, anti-seize or any other compound on the threads of the sensor.

    6

    Insert the wiring harness connectors on both sensors into the plugs on the wiring harness. Verify that they lock into the connector by checking the tab to see that it is engaged.

    7

    Remove the jack stands and lower the Jeep to the ground. Test run the engine and check your CEL or check engine light to ensure it has gone off.

How to Change a Voltage Regulator

How to Change a Voltage Regulator

The voltage regulator in your automobile controls the voltage in your electrical system, maintaining a constant current to run the electrical and electronic accessories in your car. It maintains a constant voltage of between 13 to 15 volts, depending on your automobile. The extra voltage above your batterys voltage, which is 12 volts, allows the battery to be recharged. There are two types of regulators, contained electronic regulators and contact point regulators. Unless you have a classic car, more than 25 years old, your regulator will be of the electronic variety and is either attached to your alternator or located remotely.

Instructions

    1

    Use a wrench to detach the cables from the battery. The battery is typically located under the hood, directly behind the grill of the automobile, on either the right or left side. It has two cables attached. Detach the positive cable first, it will be labeled with a "+" sign. Loosen the nut holding the cable by turning it counterclockwise. Remove the negative cable in the same way.

    2

    Locate the voltage regulator. It is either in a black plastic box on the back of your alternator, which will be labeled on the belt diagram under the hood of your car or in line in the battery cable between the alternator and the battery. Consult a repair manual for your make and model for more specifics.

    3

    Position the new regulator over the old for remote regulators, inline with the battery cable and not attached to the alternator and unplug each cable from the old regulator and plug it into the new regulator. There may be up to four cables, depending on the make and model. For cables attached with screws, loosen the screws by turning them counterclockwise with a screwdriver. Attach the cables by fitting them onto the corresponding screws on the new regulator. Tighten the screws with the screwdriver. For integrated regulators, those attached to the alternators, move directly to the next step.

    4

    Remove the screws or bolts holding the regulator to the car frame, or alternator, using a wrench or screwdriver. The type of mounting hardware depends on the car model. Position the new regulator, aligning it with the holes on the alternator or car frame. Install the mounting screws through the holes in the new regulator and tighten them, by turning them clockwise.

    5

    Replace the battery cables and tighten the cables with the wrench, making sure to attach each cable to the contact you removed it from, positive to positive and negative to negative.

How to Stop Vibration in My Harley Dyna Wide Glide

How to Stop Vibration in My Harley Dyna Wide Glide
In the last few years Harley riders, especially riders of Dyna Wide Glides, have reported improperly installed and defective rubber front motor mounts. The part has never been recalled and Harley-Davidson has never admitted the parts might be defective or improperly installed. Besides inspection of the mounts, and replacement if necessary, Harley also recommends aligning the motorcycle by loosening, but not removing, all motor mount bolts and running the engine for five seconds, during which time the mounts align themselves to the frame. The bolts are then re-tightened to manufacturer specifications. While Harley recommends the realignment, the procedure is rarely done because the mounts usually need to be replaced anyway.

Instructions

      1Make the motorcycle upright and level by slightly elevating the Wide Glide on a motorcycle jack. Do not elevate the bike. The front tire should remain within an inch of the ground.
      2 Unfasten the two bolts that secure the voltage regulator to the frame near the bottom of the down tubes with a socket wrench. Do not disconnect the voltage regulator from the wiring harness.

How to Replace the Thermostat on the 3 1 Grand Prix

The cooling system inside of the Grand Prix 3.1-liter engines comes equipped with a spring-loaded thermostat that opens and closes according to the temperature of the antifreeze. The thermostat has a bottom spring that compresses and opens the top of the thermostat to allow the antifreeze to flow through the engine block. The main purpose of the thermostat is to prevent the engine from overheating by regulating the flow of the antifreeze through the engine. If the thermostat fails, it has a safety feature that will allow the thermostat to return to the open position.

Instructions

    1

    Pull the Grand Prix with the 3.1-liter engine into a safe and level work area. Set the emergency brake and open the hood. Shut the motor off and wait two to three hours for the engine to cool down completely.

    2

    Slowly unscrew the radiator cap and set it to the side. Make sure that the cap is not hot and does not have pressure on it. Slide the drip pan underneath the radiator drain plug on the bottom of the radiator. Loosen the drain plug with the pliers and allow a couple of gallons of coolant to drain into the drain pan. Tighten the drain plug back down tight.

    3

    Locate the top radiator hose that connects to the top radiator port and the intake manifold. The other end of the radiator hose connects to the thermostat housing on top of the intake manifold. Unscrew the hose clamp from the end of the hose that is attached to the thermostat housing port with the pliers. Pull the clamp back onto the hose. Twist and pull the hose off the thermostat housing port.

    4

    Unscrew the two thermostat housing mounting bolts with a ratchet and a socket. Pull the housing off and set it to the side. Pull the thermostat out of the intake manifold and discard it into the drain pan. Scrape away any of the old gasket from the base of the intake manifold and the bottom of the thermostat housing. Wipe away the excess gasket, dirt and debris from both places with a clean rag.

    5

    Spread a thin line of the red high-temperature silicone around the bottom of the thermostat housing. Push the gasket onto the bottom of the housing so that the silicone will hold the gasket in place and act as a extra sealer. Make sure that the bolt holes are matched up on the gasket and the thermostat housing.

    6

    Set the thermostat housing back over the intake manifold and match the bolt holes up. Screw the two mounting bolts through the thermostat housing and tighten with the ratchet and socket.

    7

    Push the top radiator hose back over the thermostat housing port and line the hose clamp over the radiator hose and the port. Tighten the clamp with the screwdriver until the hose is securely tightened to the thermostat housing port.

    8

    Add the antifreeze to the radiator until it is full. Leave the cap off the radiator. Crank the motor and let the engine heat up until the thermostat opens. The thermostat generally opens around 180 degrees. When the thermostat opens, the antifreeze level will drop inside of the radiator. Keep adding more antifreeze to the radiator until the antifreeze stabilizes at the top of the radiator cap. Screw the cap on tight and turn the engine off.

95 Camaro Turns Over Wont Start

95 Camaro Turns Over Wont Start

If you have a 95 Camaro that will turn over but wont start, there are several things that you need to check before you have it hauled to a service shop. Since the motor cranks over you can be sure that you do not have a dead battery--if the battery were dead, the motor would not crank. You can also be sure that your starter and your alternator are functioning. The problem could be a clogged fuel filter, a faulty engine coil or low fuel.

Instructions

    1

    Turn the ignition to "on."

    2

    Allow the gauges to pressurize and then check the fuel level. If you have enough gas to start the car, it might be that the gas gauge is faulty, and you should have it checked. If you dont have enough gas to start the car, add one gallon of gas.

    3

    Try to start the Camaro again. If the car starts, you need to replace the fuel gauge.

    4

    Get a mechanic to change out your fuel filter. Mechanics have specialized tools for changing out fuel filters.

    5

    Have the mechanic check your engine coils. If an engine coil fails, the car will not be able to start properly.

Instructions on How to Install a Strut Tower on a 2000 Mustang GT

The 2000 Mustang GT uses McPherson Type struts on its front suspension. This type of strut makes up part of the cars steering assembly, with the damper acting as the upper steering pivot. If you are noticing your Mustang is riding rougher and not handling as well, the struts may be to blame. You can purchase the individual strut or an entire assembly. The individual strut is cheaper, but its easier to replace an intact assembly.

Instructions

Removal

    1

    Loosen the lug nuts on both front wheels with a lug wrench and raise the car with an automotive jack. Place a jack stand under the lower controls that are on each side of the car. Remove the lug nuts and both wheels.

    2

    Use a socket wrench to remove the center bolts from the brake caliper guide pins and pull the pins out of the caliper. Pull the caliper off the rotor and secure it out of the way with a piece of wire. Be caul not to damage the brake hose.

    3

    Open the hood and remove the three nuts that attach the strut assembly to the cars frame.

    4

    Locate the mounting bracket attached to the strut assembly that holds the brake line. Remove the nut and detach the bracket. Cars not equipped with ABS will not have this.

    5

    Locate the two large bolts that attach the strut to the spindle and remove the nuts with a socket wrench. You might need to hold the bolt head with another wrench to prevent it from turning. Place a large screwdriver or punch against the each bolt and tap it with a mallet to drive it out.

    6

    Pull the strut assembly down and out of the car.

Installation

    7

    Insert the new strut assembly up into place. Make sure the strut is properly aligned and that the three bolts are inserted into their holes at the top. Replace the three nuts, but do not tighten them.

    8

    Replace the two bolts that hold the strut to the spindle. Replace the nuts and tighten them to 141 to 191 ft.-lbs. of torque with a torque wrench.

    9

    Replace the brake line bracket.

    10

    Tighten the top bolts to 25 ft.-lbs. of torque.

    11

    Place the brake caliper into place and insert the guide pins. Repeat the strut replacement procedure on the opposite side. Replace the wheel and lug nuts.

Will a Car Run Without a Power Steering Pump Belt

Will a Car Run Without a Power Steering Pump Belt?

Some car owners wonder if a vehicle can operate without a power steering pump belt or if this function is safe. Not replacing a PSP belt may save money and hassle at first, but it will eventually cause huge problems.

Function

    The movement of the engine drives the PSP belt. The belt then transfers engine power to the PSP itself, which puts power steering fluid under pressure. This pressurized fluid amplifies steering wheel movement to make steering the car effortless.

Removal

    Removal of the PSP belt stops the pumps function, and eliminates power steering. Technically, a car could be driven without a PSP belt, but its not a recommended practice.

Warning

    With power steering disabled, the steering wheel becomes much less responsive and more difficult to operate. Without the circulation of power steering fluid, the steering mechanism will lose lubrication over time, ultimately causing the entire steering system to fail, endangering the life of the driver and others.

How to Paint Auto Wheels

How to Paint Auto Wheels

Painting a cars wheels is one way to give it a unique look. You might also want to match the car color, hide chrome that has seen better days, or restore wheels to their original condition. Painting your wheels can be done in a couple of days.

Instructions

    1

    Clean the wheels thoroughly. Use soap and water and scrub them, making sure to get into the crevices to remove debris. Use a hose to rinse off the wheels.

    2

    Sand your wheels to remove the current finish, and help primer stick to the wheel. If your wheels are made of chrome, sand them until you get below the surface of the chrome. 120- to 320-grit sandpaper works well. If your wheels are knicked, try to sand down below the knick or sand the knick out. Remove final debris with a 600-grit sandpaper.

    3

    Tape around the outside of the wheel by placing tape on the tire. Trace and cut a moon-shaped piece of cardboard that can be placed at an angle between the wheel and wheel well. The moon shape should be no thicker than a half-moon. It will block paint from the spray.

    4

    Lay the wheel on a flat surface. Wear a mask to avoid inhaling the paint. Spray two to three coats of primer on the wheel and allow time to dry. Sand it using 600-grit sandpaper.

    5

    Spray two to three coats of the paint that you choose. If you have an area you are not happy with due to paint chips or dripping, you can correct it with fine sandpaper and a rubbing compound to restore shine. Allow time to dry, at least 24 hours.

    6

    Apply a clear coat. Two applications should suffice. Let it dry overnight.

How to Replace an Exhaust Flange Gasket

How to Replace an Exhaust Flange Gasket

All vehicles have at least one pipe with a flange connection. The front pipe or header pipe bolted to the manifold uses a flange of some type. Many modern vehicles now connect other components, such as catalytic converters, downstream exhaust pipes and even mufflers, with flange connections. With the car on a lift and a mechanic that knows what he is doing, the repair could take a mere few minutes. With a home repair mechanic laying on his back with limited tools, the repair could become complicated.

Instructions

    1

    Inspect the pipe with the leaking flange gasket caully before attempting to disconnect it. Front-pipe-to-manifold flanges often require the rear flange to the converter or pipe be separated in order to access the leaking gasket. Sometimes unhooking an exhaust hanger somewhere down the exhaust stream might allow enough flexibility to forgo the rear flange disconnection.

    2

    Determine how the flange is connected. All front-pipe-to-manifold flanges are secured by nuts to the studs of the manifold. Downstream flange connections may use studs on one side and nuts on the other or simple nuts and bolts. Downstream studs can be distinguished by round heads which, unlike a hex bolt head, cannot be held with a wrench. Studs have grooved notches in their shafts and do not require a box-end wrench for removing the nut. Nut and bolt connections will require the bolt of the head be held stationary (with the wrench) while a ratchet and socket loosen the nut (or another wrench).

    3

    Disconnect the flange hardware. If necessary, heat the nuts of the connection with an oxyacetylene torch. Using a portable propane torch may not heat the nut up enough or could take a considerable amount of time. Heat just the edges of the nut and not the bolt. This will expand the nut. Once the nut is cherry red, turn off the torch and remove the nut. For front pipes, a ratchet, long extension and socket are most likely required.

    4

    Repeat for each nut and stud/bolt connection of the flange until all retaining hardware is removed. The studs will remain intact on their respective exhaust components.

    5

    Separate the flange connection. This is where the exhaust pipe hanger tool may come in handy. Releasing one or more exhaust hangers near the flange connection may give the exhaust system enough flexibility to access the mating surfaces of each mating flange. As mentioned earlier, it may also require separating the other connection of the exhaust component with the compromised flange gasket.

    6

    Clean each flange connections mating surface with emery cloth or medium-grit sandpaper, after allowing the exhaust system to cool down, if a torch was used.

    7

    Apply a level amount of high-temp Perma-Tex (O2 sensor-safe) compound on both sides of the gasket. Place the gasket between the flanges. On most flange connections, theres a small piece of pipe protruding on the inside of the flange to place the gasket on, depending on the type of application. Some front pipe gaskets are called "donut" gaskets and fit into a ball-flared exhaust pipe.

    8

    Reconnect the flange connection, after replacing the system on hangers, if applicable, with new hardware (nuts, bolts, washers and lock washers).

    9

    Start the vehicle and check the flange connection for leaks. If necessary, re-tighten the hardware.

How to Troubleshoot Problems With No Fire to the Points on a Massey Ferguson 175

How to Troubleshoot Problems With No Fire to the Points on a Massey Ferguson 175

There were only two engines available for the Massey Ferguson 175 over the span of the 11-year production run of this model. Both engines are 4-cylinder motors, one a diesel and the other gasoline powered. Only the latter has an ignition system, naturally. Troubleshooting a breaker point ignition system is a straightforward task, but all components involved must function correctly to deliver voltage where and when its needed.

Instructions

    1

    Set the multi-meter to the voltage scale that registers 0 to 20 volts. Check the voltage at the battery terminals. Charge the battery if the voltage is less than 12.5 volts. Clean the battery cable connections if any corrosion is present.

    2

    Turn the ignition switch to the run position. Measure the voltage at the primary side of the ignition coil. Replace the ignition switch or connecting wires if no voltage is present at the primary terminal of the ignition coil.

    3

    Measure the resistance of the primary ignition coil windings. Turn the ignition switch off and set the multi-meter to the lowest ohm scale. Place the tester leads on both ignition coil terminals. Replace the coil if resistance exceeds 5 ohms.

    4

    Replace the breaker points if they appear corroded or pitted. Replace the condenser, if no faults are found elsewhere. You can test the condenser with the proper equipment, but the cost of a new one is minimal.

How to Fill the Hydraulic Fluid in a Forklift

How to Fill the Hydraulic Fluid in a Forklift

Hydraulic fluid is the lifeblood of a forklift. Forklifts rely on hydraulics for their lifting abilities as well as steering. It is important to maintain the proper level of hydraulic fluid in a forklifts reservoir. An inadequate level of hydraulic fluid will decrease a forklifts lifting and steering abilities. An overabundance of fluid, on the other hand, can lead to other problems, such as leaks and spills. Many manufacturers recommend replacing a forklifts hydraulic oil every 1,000 hours of use.

Instructions

    1

    Consult the forklift operators manual, if available. It will tell you the specific grade of hydraulic fluid to use as well as what the particular fill level of the hydraulic tank is. If the manufacturers recommendation cannot be found, use a general purpose fluid like ISO 32 hydraulic oil.

    2

    Park the forklift on level ground. Lower the forks until they touch the ground, set the parking brake, and turn the ignition off.

    3

    Locate the hydraulic reservoir. It will have a vented fill cap on its top side and a sight glass or fill gauge on its side to indicate the fluid level.

    4

    Remove the vented fill cap. Insert the oil delivery pumps discharge nozzle into the fill tube and begin pumping fluid into the reservoir.

    5

    Observe the tanks fluid level by via the sight glass or fill gauge. Once the fluid level reaches the max fill line, stop pumping. Do not overfill the tank.

    6

    Slowly withdraw the delivery pumps fill nozzle. Use a shop towel to contain or clean up any hydraulic fluid that may have spilled onto the outside of the tank.

    7

    Finish filling the forklifts hydraulic tank by replacing the vented fill cap.

How to Use a U Joint C Frame Press Service Kit

A C-frame U-joint press kit is not something that most homeowners have in their toolboxes. In the past, if someones U-joint needed replacement, the vehicle had to go into the shop for service. Today, auto parts stores are renting and lending specialized tools for the do-it-yourself mechanic. Among tools available for rent are brake caliper kits, specialized wrenches and C-frame U-joint press service kits. Having access to this kit makes replacing U-joints something that a vehicle owner may accomplish in a home garage.

Instructions

Removing U-Joints with the C- Clamp U-Joint Press Kit

    1

    Clean all grease and grime away from the yoke.

    2

    Remove the snap ring bearing cap retainers by inserting the tips of snap ring pliers into the holes on the snap ring and squeezing the handle of the pliers together to unseat the rings from the grooves in the yoke. Pull the snap rings out.

    3

    Slip a receiving cup --- taken from the service kit and large enough to allow removal of the bearing cap from the yoke but small enough to be in full contact with the yoke --- into the open end of the C-clamp with the open end of the cup facing the inside of the C-clamp.

    4

    Slide an anvil onto the end of the forcing screw on the other side of the C-clamp. Ensure that the anvil is small enough to pass through the yoke of the U-joint.

    5

    Position the U-joint press over the yoke. Tighten the forcing screw by hand until the anvil sits on the bearing cap and the cup is firmly on the yoke over the bearing cap on the opposite side.

    6

    Tighten the forcing screw clockwise with an adjustable wrench until the bearing cap on the cup side is out of the yoke.

    7

    Turn the clamp around 180-degrees. Tighten the forcing screw by hand until the anvil is firmly against the solid portion of the U-joint and the cup is in position to receive the other bearing cap.

    8

    Tighten the forcing screw until the other bearing cap is free from the yoke. Repeat the steps for the other two bearing caps.

Installing U-Joints with the C-clamp U-joint press kit

    9

    Remove the receiving cup from the U-joint press. Remove the bearing caps from a replacement U-joint and set them aside. Ensure that the needle bearings inside the bearing cap remain on the sides of the bearing caps.

    10

    Slide the solid portion of the U-joint into the yoke so that two of the opposite ends are in the two holes in the yoke. Move the solid portion to one side in the yoke and insert a bearing cap over the end. Tap the bearing cap lightly with a hammer to get it started into the hole in the yoke.

    11

    Position the U-joint press over the yoke so that the anvil is in contact with the bearing cap. Hand-tighten the forcing screw until the other side of the C-clamp is firmly in contact with the yoke. Tighten the forcing screw, pressing the bearing cap into the hole in the yoke. Keep pressing the cap into the yoke until the groove for the snap ring is clearly visible.

    12

    Move the solid center of the U-joint to the other side of the yoke far enough that a bearing cap can be partially inserted on the end, but not so far that it comes out of the first bearing cap. This ensures that the needle bearings inside the caps do not fall out of place.

    13

    Turn the clamp around 180 degrees and position the anvil on the second bearing cap. Hand-tighten the forcing screw until the other side of the C-clamp is solidly against the yoke. Press the second bearing cap into the other hole in the yoke by turning the forcing screw until the groove for the snap ring retainer is visible, ensuring that the solid center of the U-joint does not come out of either bearing cap. Repeat for the other bearing caps. Reinstall the snap rings.

How to Make Denso Shims

The accelerator pedals in Toyota automobiles either come from Denso or CTS manufacturers. The CTS accelerator pedal has a demonstrable tendency to stick because of a friction arm design. Shims are a necessary, but temporary, modification that brings the pedals closer to the quality found in a Denso accelerator. These shims can be bought and installed at Toyota dealerships. But a Denso shim also can be crafted with basic metalworking skills.

Instructions

    1

    Determine the thickness required for the shim. Locate the part number stamped near the top of the accelerator pedals neck. A chart in the accelerator module recall documentation indicates the shims required thickness based upon this part number. This value ranges from 0.055 inches (1.4 mm) to 0.114 inches (2.9 mm). A majority of these replacements will require either a 0.070-inch (1.8 mm), 0.079-inch (2.0 mm) or 0.091-inch (2.3 mm) thickness.

    2

    Use metal cutters to cut a square shim out of steel measuring one inch (25 mm) on each side. The thickness of the shim should fall between 0.008 inches (0.2 mm) to 0.020 inches (0.5 mm) greater than the requirement outlined in Step 1.

    3

    Position the shim in a metal press so that a 0.079-inch (2 mm) lip is exposed on either side. Use the stamp to squeeze the metal until the center of the shim is the required thickness, but the lip remains at its original thickness. The result resembles a "U" shape.
