Crankshaft Main Bearing Seal: Service and Repair
Removal
NOTE: If crankshaft rear oil seal replacement is the only operation being performed, it can be done in the vehicle. If the oil seal is being replaced in
conjunction with a rear main bearing replacement, the engine must be removed from the vehicle. To replace the seal only, proceed as follows:
1. Disconnect battery ground cable from battery, then remove the starter motor.
2. Disconnect the transmission from the engine and slide it back.
3. On a manual shift transmission, remove the pressure plate and cover assembly and the clutch disc.
4. Remove flywheel attaching bolts and remove the flywheel and engine rear cover plate.
CAUTION: Avoid scratching or damaging the oil seal surface.
5. Use an awl to punch one hole into the seal metal surface between the seal lip and block. Screw the threaded end of a Jet Plug Remover or
equivalent into the hole, and remove the seal.
6. Clean the oil seal recess in the cylinder block and main bearing cap.
