Important: 

•	Do not reuse the crankshaft oil seal or rear cover gasket.

•	Do not apply any type of sealant to the rear cover gasket, unless specified.

•	The special tool in this procedure is used to properly center the crankshaft rear oil seal.

•	All gasket surfaces should be free of oil or other foreign material during assembly.

•	The crankshaft rear oil seal MUST be centered in relation to the crankshaft.

•	An improperly aligned rear cover may cause premature rear oil seal wear and/or engine assembly oil leaks.




1. Apply a 5 mm (0.2 in) bead of sealant, 20 mm (0.8 in) to the 2 joints (a) at the rear of the block/pan. Refer to Adhesives, Fluids, Lubricants, and Sealers.

1. Install the J 41479-2A cone and bolts onto the rear of the crankshaft.



2. Install the NEW rear housing gasket (1), rear housing with seal (2), rear housing-to-engine bolts (3) and oil pan-to-rear housing bolts (4).

Notice: Use the correct fastener in the correct location. Replacement fasteners must be the correct part number for that application. Fasteners requiring replacement or fasteners requiring the use of thread locking compound or sealant are identified in the service procedure. Do not use paints, lubricants, or corrosion inhibitors on fasteners or fastener joint surfaces unless specified. These coatings affect fastener torque and joint clamping force and may damage the fastener. Use the correct tightening sequence and specifications when installing fasteners in order to avoid damage to parts and systems.

3. Tighten the rear housing-to-engine bolts (3) until snug. Do not overtighten.
