Crankshaft Rear Oil Seal Removal
6. Install #10 sheet metal screws in the drilled holes and remove the rear seal with a slide hammer.
CLEANING
Clean the crankshaft journal with a suitable solvent and dry with a clean shop towel or compressed air. Wipe the inside bore of the crankshaft seal
retainer with a clean shop towel.
INSPECTION
Inspect the crankshaft journal for gouges, nicks, or other imperfections. If the seal groove in the crankshaft is excessively deep, install the new seal
1/8" deeper into the retainer bore, or obtain a crankshaft wear sleeve that is available in the aftermarket.
INSTALLATION
CAUTION: The seal lip and the sealing surface on the crankshaft must be free from all oil residue to prevent seal leaks. The crankshaft and seal
surfaces must be completely dry when the seal is installed. Use a soap and water solution on outside diameter of seal to ease assembly.
1. Install the seal pilot, provided in the replacement kit, onto the crankshaft.
2. Using the provided alignment/installation tool, start the seal over the pilot and into the retainer by hand.
Seal Installation Using Alignment Tool And Hammer
3. Using a ball peen hammer, strike the tool at the 12, 3, 6, and 9 o'clock positions until the alignment tool bottoms out on the retainer.
4. Remove the seal pilot.
5. Install the flywheel or converter drive plate. Tighten the bolts to 137 Nm (101 ft. lbs.) torque.
