Crankshaft Main Bearing Seal: Service and Repair
REMOVAL
1. Disconnect the battery negative cables.
2. Remove the transmission and transfer case (if equipped).
3. Remove the clutch cover and disc (if manual transmission equipped).
4. Remove the flywheel or converter drive plate.
5. Drill holes 180 degrees apart into the seal. Be careful not to contact the drill against the crankshaft.
6. Install #10 sheet metal screws in the drilled holes and remove the rear seal with a slide hammer (Fig. 108).
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. 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.
2. 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.
3. Install the seal pilot, provided in the replacement kit, onto the crankshaft.
4. Using the provided alignment/installation tool, start the seal over the pilot and into the retainer by hand.
5. 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 (Fig. 109).
