Special Tool(s):

Material:

CAUTION: Remove the cylinder heads before removing the crankshaft. Failure to do so can result in engine damage.

CAUTION: During engine repair procedures, cleanliness is extremely important. Any foreign material, including any material created while cleaning gasket surfaces that enters the oil passages, coolant passages or the oil pan, can cause engine failure.

NOTE: The flywheel, crankshaft rear oil slinger, crankshaft rear seal and the crankshaft rear seal retainer plate must be removed before mounting the engine on the engine stand.

NOTE: For additional information, refer to the exploded view.

1. Remove the 8 bolts and the flywheel.





2. Remove the engine/transmission spacer plate.





3. Using the special tools, remove the crankshaft rear oil slinger.





4. Using the special tools, remove the crankshaft rear seal.





5. Remove the 8 bolts and the rear seal retainer plate.

- CAUTION: Do not use metal scrapers, wire brushes, power abrasive discs or other abrasive means to clean the sealing surfaces. These tools cause scratches and gouges which make leak paths. Use a plastic scraping tool to remove all traces of old sealant.

Clean the mating surfaces with silicone gasket remover and metal surface prep. Follow the directions on the packaging.
- Inspect the mating surfaces.
