Tools Required

J 39084 Rear Main Seal Installer

1. Remove the transmission.
2. Remove the flywheel.



3. Remove and discard the oil seal.
4. Clean the oil seal bore in the block thoroughly before installing a new oil seal.

Important: The crankshaft surface must be clean and smooth to prevent damaging the seal lip when a new oil seal is installed.

Because of rear crankshaft wear or grooving, the service seal will be positioned flush with the rear block face. The position of the new seal will be controlled by the installation of J 39084 . The reason for the positioning of the seal in a new location is to provide a new surface for the oil seal to ride on.
5. Inspect the rear portion of the crankshaft where the oil seal makes contact. Look for wear due to the rubbing action of the oil seal or a buildup of dirt.
