How to Fix the Clutch in a Nissan Frontier
The clutch is one of the most important parts of any vehicle, letting you shift gears and adjust your speed. When your Nissan Frontiers clutch is working properly, you get the most control out your truck especially while you are driving out in the open roads. All clutches, however, will need replacement at one point or the other. Once your Nissan starts to screech and grind each time you use the clutch, you need to either replace a defective part in your clutch system, or replace the entire clutch system with a clutch kit.
Instructions
- 1
Lift the truck. Use a hydraulic jack to life the truck. If your truck has a front wheel drive system, lift the front wheels. If your truck has a rear wheel drive system, lift the rear wheels. Support the weight of the truck with a jack stand.
2Remove the axle. Unscrew the bolts that keep the driveshaft to the differential with a wrench. Once the bolts are removed, you can slip the driveshaft from the universal joint in the differential. Make sure that the wire caps on the universal joint and the driveshaft do not hit the ground, because impact can damage the sensitive pieces. Place a pan underneath the transmission tail housing to protect your floor from dripping transmission fluid.
3Unwire the harnesses. Unscrew the housing on the transmission and remove any wires that keep the transmission harnessed. Mark all of the wires so that you know where to connect them after you are done fixing the clutch. Also remove the starter which is connected by a wire to the transmission.
4Support the engine. Place a jack stand under the engine, so that you will be able to take the transmission mount out of the cross member. Once the cross member is free, you can remove the bolts around the transmission bell housing. This will allow you to pull the transmission from the rest of the engine. Do this until the pressure plate is revealed from under the input shifts.
5Remove the transmission. Unscrew the bolts that keep the flywheel attached to the pressure plate and then remove the transmission fully. Make sure that the flywheel is not damaged, otherwise it needs to be replaced. Also be sure to wipe the crankshaft flange clean.
6Replace the clutch. Attach the new pressure plate onto the flywheel. Once attached, you can insert the clutch disc and then tighten using the appropriate amount of torque indicated in the packaging of the clutch replacement kit that you bought. Add a bit of grease on the bearings so that you can add the release bearing to the clutch disc.
7Put parts back in place. Insert the transmission back into place, until the shaft from the transmission enters the hole in the clutch disc. Install the bell housing again using bolts, and then gently lower the truck back onto the ground.

How to Bleed a 1990 Honda Accord Clutch
The Honda Accord is the mid-level offering in Hondas Civic, Accord and Camry line of cars. In 1990, the Accord was made 5 inches longer. It received a larger 2.2-liter, four-cylinder engine and two new transmissions, a five-speed manual or a four-speed automatic. The five-speed manual transmission features a hydraulically actuated clutch, with a master cylinder mounted on the firewall next to the brake master cylinder and a slave cylinder mounted on the bell housing.
Instructions
- 1
Raise the front of the Accord with a jack and support it with jack stands on each side of the vehicle.
2Locate the clutch master cylinder next to the brake master cylinder. Clean the top of the master cylinder with a shop rag. Fill the cylinder with fresh brake fluid if necessary.
3Put on safety goggles. Loosen the bleeder screw on the clutch slave cylinder with a wrench but do not open it yet. The clutch slave cylinder is located on the drivers side of the car on the bell housing. Fill a plastic bottle about 1/3 full of brake fluid. Attach a 3-foot length of clear plastic tubing to the bleeder screw and insert the other end into the plastic bottle so it is below the level of the fluid.
4Instruct an assistant to depress the clutch pedal three or four times and then hold pressure on the pedal. Open the bleeder screw with a wrench while your assistant maintains pressure on the pedal. Brake fluid and air bubbles will exit the slave cylinder. Close the bleeder screw. Your assistant can now release the pressure on the clutch pedal.
5Check the fluid level in the master cylinder. You must keep checking the fluid level, as you bleed the slave cylinder, because it will go down every time you open the bleeder screw. Repeat the above process until no air exits the slave cylinder.
6Wipe up any spilled brake fluid with a shop rag. Raise the front of the vehicle with the jack and remove the jack stands. Lower the vehicle. Make sure the master cylinder is full.

Manual Transmission Clutch Problems
A properly functioning clutch gives you total control of the gears of a manual transmission. However, when a clutch is acting up, it can be troublesome, especially in busy traffic where the clutch is used often.
Slippage
When the thickness of the clutch disc has decreased due to wear, the pressure plate can not clamp with the same amount of force as usual. This allows pressure to drop causing the clutch to slip. As the clutch continues to slip it gets hotter and hotter causing damage to the flywheel and pressure plate.
Contamination
Oil contamination cause a clutch to fail before it should The source of the oil is mainly from leaks in either the rear crankshaft seal or the input shaft seal. If the clutch experiences jerking once its engaged, then oil contamination is one likely cause.
External
Several external problems can cause clutch chatter problems, such as engine or transmission mounts that have broken. Drive train and chassis components being misaligned can also cause issues with a manual transmissions clutch.

How to Measure for a Harley Clutch Cable Replacement
To properly service your Harley, you must be aware of the location of your clutch cable adjuster. The adjuster must be accessible if you are going to properly maintain your bike. Usually, the most variation in cable lengths is the distance between the adjuster and the clutch lever. It is not necessary to measure Harley-Davidson stock clutch replacement cables; the part is always simply sold as "stock" length. However, you must always measure the clutch cable when you replace your stock handlebars or install handlebar risers. It is best to install the new handlebars or risers first, then measure for your replacement cable immediately after.
Instructions
- 1
Tape one end of the piano wire to the top of your clutch lever housing. Ensure that the wire extends across the entire breadth of the housing.
2Turn the handlebars all the way to the right to ensure your clutch cable will cover your full turning radius.
3Route the piano wire down your forks. Tape the wire to your forks approximately where the clutch cable adjuster was located on your old clutch cable.
4Route the wire two inches beyond the spot where your old clutch cable entered your primary case. Mark that termination point on the wire with a third piece of tape.
5Remove the piano wire from your motorcycle. Remove the first two pieces of masking tape. Measure the distance from the end of the wire to the third piece of masking tape with a steel or cloth measuring tape.

How to Adjust a Horton Clutch Fan
All automotive engines use a fan to keep the engine cool during operation. If you are having problems with your engine overheating, it could be due to the Horton clutch fan installed in your car. When the fan does not operate, the engine overheats and turns off. As this could happen during operation, adjusting the Horton clutch fan could keep it attached to the serpentine belt on your engine. You dont have to be a car mechanic to adjust the clutch fan. You can do it yourself with little hassle.
Instructions
- 1
Park your car on a level surface, and apply the emergency brake. Pop the hood, so you gain access to the engine.
2Use a socket to remove the upper fan shroud from the Horton clutch fan. This is the protective piece on the top of the fan.
3Use a belt tool to suspend the serpentine belt. Make sure that the serpentine belt is making contact with the Horton clutch fan. Adjust or replace the belt if needed.
4Use a socket set to loosen the bolts securing the clutch fan to the car. Adjust the fan so you can get a good fit on the serpentine belt if needed.
5Tighten the bolts and situate the serpentine belt to the fan. Release the belt by removing the belt tool. Close the hood.

Manual Transmission Clutch Repair Information
The clutch is a key part of a manual transmission, which is often considered to be very reliable. However, because the clutch takes all the wear and tear, it can be the weakest link in a manual transmissions drivetrain. For this reason, information on the repair of this part can be beneficial for vehicle owners.
Causes
Certain factors can cause problems to occur with your clutch, such as heavy traffic which produces stop-and-go of driving. Constantly engaging and disengaging the clutch will cause it to wear down over time.
Noises
The noises from a clutch can reveal the problems it is having. A squealing noise from the clutch usually indicates worn out bearings, while other noises can be due to issues such as flywheel bolts being too loose.
Repair
When repairing a clutch, it is recommended to replace all of its major parts---such as the clutch disc and pressure plate assembly---instead of just the parts that have obvious damage. Because oil and dirt on a flywheel can result in later clutch issues, it should be replaced or resurfaced as well.
