Removal

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, may 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 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.
^ Alternately tighten the 2 bolts one turn at a time until the crankshaft rear seal retainer-to-cylinder block seal is released.
^ Remove the crankshaft rear seal retainer.





8. CAUTION: Only use a 3M Roloc(R) Bristle Disk, (2-in white, part number 07528) to clean the crankshaft rear seal retainer plate. Do not use metal scrapers, wire brushes or any other power abrasive disk to clean the crankshaft rear seal retainer plate. These tools cause scratches and gouges that make leak paths.

Clean the crankshaft rear seal retainer plate using a 3M Roloc(R) Bristle Disk, (2-in white, part number 07528) in a suitable tool turning at the recommended speed of 15,000 rpm.
^ Thoroughly wash the crankshaft rear seal retainer plate to remove any foreign material, including any abrasive particles created during the cleaning process.

9. CAUTION: Place clean, lint-free shop towels over exposed engine cavities. Carefully remove the towels so foreign material is not dropped into the engine. Any foreign material (including any material created while cleaning gasket surfaces) that enters the oil passages or the oil pan, may cause engine failure.

CAUTION: Do not use wire brushes, power abrasive discs or 3M Roloc(R) Bristle Disk (2-in white, part number 07528) to clean the sealing surfaces. These tools cause scratches and gouges that make leak paths. They also cause contamination that will cause premature engine failure. Remove all traces of the gasket.

Clean the sealing surfaces of the cylinder block in the following sequence.
1 Remove any large deposits of silicone or gasket material.
2 Apply silicone gasket remover and allow to set for several minutes.
3 Remove the silicone gasket remover. A second application of silicone gasket remover may be required if residual traces of silicone or gasket material remain.
4 Apply metal surface prep 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.
