How to Remove a Timing Cover on a Small Block Chevy

Underneath the timing cover of a small-block Chevrolet engine sits the timing chain and gears. Most often this cover is removed in order to replace the timing chain, but it is also part of the disassembly when rebuilding a small Chevy V8. Though the timing cover sits on the front of the motor, it is obscured by other engine components mounted in front. To remove the timing cover, these obstacles must be removed first.

Instructions

1

Drain the engine coolant and engine oil. On some Chevy models, the oil pan will also need to be removed in order to take off the timing cover.

2

Remove the bottom radiator hose by loosening the screw clamp with a flat screwdriver, draining the coolant into the waste bucket. The bottom hose is the one that hooks to the water pump. If the top hose and radiator are in the way, they will need to be removed as well.

3

Take off the cooling fan and then remove the drive belts.

4

Remove the water pump. Allow the excess fluid to drain from the block into the waste bucket.

5

Remove the harmonic balancer with a harmonic balance puller. Do not pull on the edges of the harmonic balancer or it will separate the rubber from the metal housing.

6

Take off any additional brackets that may be in the way.

7

Disconnect the engine mounts if the engine needs to be raised in order to access the timing cover.

8

Remove the bolts on the timing cover and pull the cover loose. If you did not take off the oil pan, then open the timing cover slightly and tilt it back. Cut the front oil seal off evenly with the engine. Remove the cover.
