Rear Main Bearing Oil Seal: Installation

1. Remove the rear main bearing cap. Wipe the seal surface area of the crankshaft until it is clean. Apply a thin coat of engine oil. Position the upper seal into the cylinder block. The lip of the seal faces toward the front of the engine.
2. Coat both sides of the lower seal end tabs w/Jeep Gasket-in-a-Tube, or equivalent. Do not apply sealant to the lip of the seal. Coat the outer curved surface of the lower seal with soap and the lip of the seal w/engine oil. See Fig 1.
3. Position the lower seal into the bearing cap recess and seat it firmly. Coat both chamfered edges of the rear main bearing cap w/Jeep Gasket-in-a-Tube, or equivalent, See Fig 1.
   CAUTION: Do not apply sealant to the cylinder block mating surfaces of the rear main bearing cap because the bearing-to-journal clearance would be altered.
4. Install the rear main bearing cap. Tighten all main bearing bolts to 80 ft-lbs (108 Nm) torque.
