REMOVAL & INSTALLATION
See Figures 1 through 5
The rear main bearing seal may be replaced without removing the crankshaft. Both upper and lower seals must be replaced at the same time.
Extreme care should be exercised when installing this seal to protect the sealing bead located in the channel on the outside diameter of the seal. An installation tool can be used to protect the seal bead when positioning seal.
- Remove the oil pan and oil pump.
- Remove the rear main bearing cap, and pry the seal out from the bottom with a small prytool.
- Remove the upper seal with a small hammer and a brass pin punch. Tap on one end of the seal until the opposite end can be gripped with pliers.
- Clean the bearing cap and crankshaft.
- Coat the lips and bead of the seal with a light engine oil. Do not get oil on the seal ends.
- Insert the new seal into the bearing cap, rolling it into place with your finger and thumb. Press lightly on the seal, so that the seal tangs on the cap dont cut the bead on the back of the seal.
- Lubricate the lip of the new oil seal and slowly push it into place while turning the crankshaft. Make sure that the seal tangs dont cut the bead on the back of the seal.
- Install the main bearing cap and tighten to specifications.
