Rear Crankshaft Main Bearing Seal: Service and Repair

TOOL REQUIRED
^ J 38817 Rear Main Seal Installer

REMOVAL
1. Remove the transmission. See Transmission and Drivetrain.
2. Remove the flywheel. See Transmission and Drivetrain.





3. The preferred method of seal removal is by drilling a (1/8 inch) hole in the metal seal body and removing the seal with a body dent puller (slide hammer). Seal removal with a screwdriver blade between the seal lips and the crankshaft is also possible but extreme care is required to avoid damage to the crankshaft sealing surface.

INSTALLATION
1. Replace a small dab of RTV sealant at the crankcase split line across the end of the upper/lower crankcase seal.





2. Lubricate the rear main seal sealing lips and engine block with engine oil and slide the seal over the arbor of the Rear Main Seal Installer. The garter spring faces in.
3. Thread Rear Main Seal Installer into the crankshaft flange and install the seal by turning the handle until the tool bottoms against the crankcase.
4. Install the flywheel. See Transmission and Drivetrain.
5. Install the transmission. See Transmission and Drivetrain.
