Tools Required

J 38817-A Rear Main Seal Installer

1. Remove the transmission. Refer to Transmission Replacement in Automatic Transmission.
2. Remove the flywheel. Refer to Engine Flywheel Replacement .



3. The preferred method of seal removal is by drilling a (1/8 in) hole in the metal seal body and removing the seal with a body dent puller (slide hammer). Seal removal with a screwdriver blade between the seal lips and the crankshaft is also possible but extreme care is required to avoid damage to the crankshaft sealing surface.

1. Replace a small dab of RTV sealant at the crankcase split line across the end of the upper/lower crankcase seal.



2. Lubricate the rear main seal sealing lips with engine oil and slide the seal over the arbor of the J 38817-A . The garter spring faces in.
3. Thread J 38817-A into the crankshaft flange and install the seal by turning the handle until the tool bottoms against the crankcase.
4. Install the flywheel. Refer to Engine Flywheel Replacement .
5. Install the transmission. Refer to Transmission Replacement in Automatic Transmission.
