Rear Main Bearing Oil Seal: Installation
Fabricate installing tool as shown in illustration. Coat seal lips and seal bead of upper seal. Keep oil off mating ends. Position tip of tool between crankshaft and seal seat in cylinder block and position seal between crankshaft and tip of tool so that seal bead contacts tip of tool. Roll seal around crankshaft using tool as a "shoehorn" to protect seal bead from sharp corner of seal seat surface. Make sure that oil-seal lip is positioned toward front of engine.
NOTE:
Installation tool must remain in position until seal is positioned with both ends flush with block. Remove tool being careful not to withdraw seal.
Install lower half of seal in bearing cap, using tool as a "shoehorn". Feed seal into cap using light pressure with thumb and finger. Install bearing cap with sealant applied to face, being careful to keep sealant off the seal split line.
