Rear Crankshaft Main Bearing Seal: Service and Repair



Crankshaft Rear Seal




Special Tool(s)







Material

Removal
1. Remove the transmission.





2. Remove the 10 bolts and flexplate.
^ Discard the bolts.





3. NOTE: Use extreme care when removing the flywheel front adapter to prevent damage to the alignment dowel pin.

Remove the flywheel front adapter.





4. CAUTION:
^To prevent engine damage, do not remove the rear primary crankshaft flange bolts under any circumstances. If the flange is removed and reinstalled, it will result in engine vibration and premature transmission component wear.
^Drill only deep enough to penetrate the seal. Engine damage will occur if the seal is drilled too deep.
^On original service seals, if equipped, the wear ring will be removed separately.

Using a center punch, mark a location for 2 holes 180 degrees apart, 9.53 mm (0.375 in) from the outer diameter of the crankshaft flange. Using a drill bit of the appropriate size for the Slide Hammer being used, drill a hole on each side of the crankshaft rear seal as shown. Drill the holes to a depth of 8.76 mm (0.344 in) to capture the metal case of the crankshaft rear seal as well as the wear ring.





5. Using the 2 drilled holes, the Slide Hammer and a commercially available body dent puller attachment, walk the seal out of the rear cover by alternating from side to side to remove the crankshaft rear seal.
^ Discard the crankshaft rear seal.

Vehicles with an original service seal.





6. NOTE: Original equipment seals will not have a wear ring. If a service part has previously been installed, it will have a wear ring. If the service part has a redesigned seal, the wear ring will have been removed with the seal in the previous step. If the service part was an original service seal, the wear ring will remain in the engine after the seal has been removed.

If the wear ring remained in the engine after removing the seal, use the Crankshaft Rear Wear Ring Remover to remove and discard the crankshaft rear seal wear ring.

All vehicles





7. Clean and inspect the crankshaft sealing surface.

Installation

Vehicles with an original service seal





1. NOTE: The crankshaft rear seal and wear ring are a one-piece design and need to be installed as an assembly. Do not separate the wear ring from the crankshaft rear seal or damage to the seal may occur.

NOTE: An original service seal will have a wear ring without a flange and pre-applied threadlock.

NOTE: Apply a bead of threadlock around the circumference of the outer rear edge of the secondary crankshaft flange.

NOTE: Lubricate the outer diameter of the rubber seal with a solution of dish soap and water (approximately 50/50 mix) prior to assembly. Do not use any other type of lubricant.

Lubricate the outer diameter of the rubber seal with a solution of dish soap and water.





2. Using the Crankshaft Rear Seal and Wear Ring Installer, install the new crankshaft rear seal and wear ring assembly.

Vehicles with a redesigned seal





3. NOTE: A redesigned seal will have a flanged wear ring and pre-applied threadlock.





4. NOTE: NOTICE: The crankshaft rear seal and wear ring are a one-piece design and need to be installed as an assembly. Do not separate the wear ring from the crankshaft rear seal or damage to the seal may occur.

Identify the metal face of the wear ring. This face must be installed so it is on the outside of the engine (facing the transmission).





5. NOTE: Lubricate the outer diameter of the rubber seal with a solution of dish soap and water (approximately 50/50 mix) prior to assembly. Do not use any other type of lubricant.

Lubricate the outer diameter of the rubber seal with a solution of dish soap and water.





6. NOTICE: Make sure the crankshaft alignment dowel fits in the dowel recess hole in the Crankshaft Rear Seal and Wear Ring Installer base or engine damage may occur.

Install the Crankshaft Rear Seal and Wear Ring Installer base and 2 bolts to the crankshaft flange.





7. NOTE: When positioning the crankshaft rear seal and wear ring assembly on the Crankshaft Rear Seal and Wear Ring Installer base, align it to the opening on the engine rear cover and manually start the crankcase rear seal installation.

Position the crankshaft rear seal and wear ring assembly on the Crankshaft Rear Seal and Wear Ring Installer base.





8. NOTICE: The plastic step-up tool increases the flat surface area of the Crankshaft Rear Seal and Wear Ring Installer. Failure to use the plastic step-up tool during installation will result in damage to the crankshaft rear seal and wear ring assembly.

Insert the plastic step-up tool in the Crankshaft Rear Seal and Wear Ring Installer with the step-edge toward the installer.





9. NOTICE: The crankshaft rear seal face and the wear ring must be flush with the rear engine cover or damage to the crankshaft rear seal or wear ring may occur.

NOTICE: Do not allow the engine to rotate during the installation of the crankshaft rear seal and wear ring assembly or damage to the crankshaft rear seal or wear ring may occur.

Using the Crankshaft Rear Seal and Wear Ring Installer, install the new crankshaft rear seal and wear ring assembly until the installation tool contacts the rear engine cover.

All vehicles
