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 flexplate, crankshaft rear seal and the crankshaft rear oil slinger must be removed before mounting the engine on the engine stand.

1. Remove the engine.





2. Remove the bolts and the flexplate.

3. CAUTION: Do not use the oil pan to support the engine.

Lower and support the engine assembly on wood blocks.





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





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





6. Remove the bolts and the crankshaft 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 and inspect the sealing surfaces.

7. CAUTION: Do not use the oil pan to support the engine.

Lower and support the engine assembly on wood blocks.
