Crankshaft Rear Seal with Retainer Plate

Special Tool(s):

Material:

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: This procedure is for removal of the crankshaft rear seal and retainer plate and requires removal of the oil pan. If you are only removing the crankshaft rear seal, refer to Crankshaft Rear Seal.

1. Remove the oil pan.
2. Using the special tools, remove the engine from the stand.





3. Disconnect the crankshaft position (CKP) sensor electrical connector.





4. Remove the bolt and the CKP sensor.





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





6. Remove the 8 crankshaft rear seal retainer bolts.





7. Install the 2 M6 oil pan bolts (finger tight) into the 2 threaded holes in the crankshaft rear seal retainer.
1 Alternately tighten the 2 bolts one turn at a time until the crankshaft rear seal retainer-to-cylinder block seal is released.
2 Remove the crankshaft rear seal retainer.





8. CAUTION: Place clean, lint free shop towels over exposed engine cavities. Carefully remove the towels so foreign material is not dropped into the engine.

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 that make leak paths. Use a plastic scraping tool to remove all traces of the gasket.

CAUTION: Observe all warnings or cautions and follow all application directions contained on the packaging of the silicone gasket remover and the metal surface prep.

Clean sealing surfaces of the crankshaft rear seal retainer and cylinder block.
1 Remove any large deposits of silicone or gasket material with a plastic scraper.
2 Apply silicone gasket remover, following package directions, and allow to set for several minutes.
3 Remove the silicone gasket remover with a plastic scraper. A second application of silicone gasket remover may be required if residual traces of silicone or gasket material remain.
4 Apply metal surface prep, following package directions, to remove any remaining traces of oil or coolant and to prepare the surfaces to bond. Do not attempt to make the metal shiny. Some staining of the metal surfaces is normal.
