crankshaft wear sleeve. If a crankshaft wear sleeve is not necessary, refer to Step 2.
a. Clean and polish the crankshaft of imperfections.
b. Use Tooling (A) to clean the outside diameter of the crankshaft and the inside
diameter of the crankshaft wear sleeve.
c. Apply Tooling (B) to the outside diameter of the crankshaft and the inside diameter of
the crankshaft wear sleeve.
d. Use Tooling (C) to install the crankshaft wear sleeve.
Note: Leave the shipping sleeve in place to install the crankshaft rear seal. The crankshaft
rear seal must be installed dry.
Note: If the seal group, O-ring seal, and the shipping sleeve are separated, these
components should not be used.
2. Lubricate the O-ring seal with clean engine oil that is on the back of the crankshaft rear seal
(1).
3. Position crankshaft rear seal (1) and the shipping sleeve over the crankshaft. Push
crankshaft rear seal (1) in place. This will dislodge the shipping sleeve.
Note: Do not remove the shipping sleeve until bolts (2) are installed.
4. Install new bolts (2) hand tight. Then, tighten bolts (2) in numerical sequence, shown in
Illustration 2. Tighten bolts (2) to a torque of 12 ± 3 N·m (106 ± 27 lb in).
End By:
a. Install the flywheel. Refer to Disassembly and Assembly, "Flywheel - Install".
