Rear Main Bearing Oil Seal: Installation
- Fabricate an oil seal installation tool, if one is not supplied with replacement oil seal. See Fig 1. Coat seal lips with engine oil. Keep oil off of seal ends. Position tool between crank- shaft and seal groove in cylinder block. Position seal between tip of tool and crankshaft.
- Roll seal around crankshaft, using tool as a "shoehorn" to protect seal from sharp corner of seal groove in cylinder block. Tool must remain in position until seal is positioned with both ends flush with block.
- Install lower seal into bearing cap, using tool as a "shoehorn". Feed seal into cap using light pressure with thumb and finger. Apply sealer to cap-to-block mating surface of cylinder block, being careful to keep sealer off the seal split line. Install and tighten bearing cap.
