Rear Crankshaft Oil Seals Removal
REAR CRANKSHAFT OIL SEALS REMOVAL - 2000 MODEL YEARTOOLS REQUIRED
- SA9121E Rear Crank Seal Replacer
IMPORTANT: The Rear Crank Seal Replacer SA9121E installs the seal 1.0 mm (0.040 in.) deeper into the carrier than the factory. Installing the seal 1.0 mm (0.040 in.) will make sure the seal lip contacts a different surface area on the rear crankshaft flange.
There are two methods of replacing the rear crankshaft oil seal. Special tools are required for both procedures to make sure the seal lip is not damaged.
NOTICE: To prevent oil leaks and seal damage, the engine's oil pan must be removed if the rear oil seal carrier requires replacement.
1. Replacement of rear crankshaft oil seal. Method one:
1.1 If the rear oil seal carrier is removed from the cylinder block, use a screwdriver and hammer to tap out the oil seal.
NOTICE: Do not allow screwdriver blade to contact crankshaft flange seal surface.
1.2 If the rear oil seal carrier is not removed from the cylinder block, use the pry tangs provided in the carrier to remove the seal with a screwdriver and hammer.
1.3 Check the oil seal lip contact surface of the crankshaft for scratches or damage. If rust is present, remove using Scotch~Brite� pad. Do not use emery cloth, sandpaper or other abrasive materials. Rust removal is necessary to prevent seal lip damage during installation.
1.4 With the crankshaft and rear carrier installed on the cylinder block, use Rear Crank Seal Replacer SA9121E to install a new oil seal. The service tool prevents rolling the seal's lip. Never tap on seal or seal installer with a hammer.
1.5 Apply a film of oil to the seal lip and inside diameter of the carrier.
2. Replacement of rear crankshaft oil seal. Method two:
2.1 If the rear crankshaft oil seal carrier is not installed on the cylinder block, apply light coat of engine oil to the seal lip and inside diameter of the carrier.
IMPORTANT: The rear crankshaft oil seal should be installed with the crankshaft and carrier assembled in the cylinder block whenever possible. The Rear Crank Seal Replacer SA9l21E is designed to pull the seal in to place and make sure it is properly seated.
2.2 Using Rear Crank Seal Replacer SA9I2lE and a arbor press, push the oil seal into the carrier. Never tap on the seal or seal installer with a hammer.
IMPORTANT: The Rear Crank Seal Replacer SA9121E is designed to guide the seal over the rear crankshaft flange. The service tool prevents rolling the seal's lip.
2.3 Apply a 2.0 mm (0.080 in.) diameter bead of RTV to the carrier.
IMPORTANT:Assemble while RTV is still wet (within three minutes). Do not wait for RTV to skin over.
2.4 Install the four rear crankshaft seal carrier bolts.
