Keep all parts clean from contaminants.Contaminants may cause rapid wear and shortened component life.
Note: The rear seal and the wear sleeve must be replaced at the same time. Once the seal and the wear sleeve are separated, these components cannot be used again. Refer to Special Instruction, SMHS8508, "Special Handling Information and Installation Instructions for Crankshaft Seal Groups that Have Hydrodynamic Grooves In the Sealing Lip" before the seal is serviced.

Note: Do not use any type of lubricant during the installation of the rear crankshaft seal and wear sleeve.
Before installation of the rear crankshaft seal and the wear sleeve, inspect the crankshaft for scratches. Also, inspect the crankshaft for any distortion on the surface that may lead to an out of round condition. Use a polishing cloth in order to remove any imperfections on the crankshaft.
Clean the outside diameter of the crankshaft (2) and the inside diameter of the seal assembly (1) .
Fasten Tooling (B) to crankshaft (2) with Tooling (C) .
The front and rear seals and wear sleeves have different spiral grooves in the seal. Because of this type of design, the front seal group for an engine is different from the rear seal group. If a seal group is installed on the wrong end of the engine, oil can actually be taken out of the engine instead of moving oil back into the engine.
Note: Install the seal with the arrow that shows the direction of crankshaft rotation toward the rear of the engine.
Position seal assembly (1) on Tooling (B) . Install Tooling (E) on Tooling (B) . Lubricate the face of the washer on Tooling (D) . Install Tooling (D) on Tooling (E) .
Tighten Tooling (D) until Tooling (E) contacts Tooling (B) .
Remove Tooling (C) , Tooling (D) and Tooling (E) .
Remove Tooling (C) and Tooling (B) from the crankshaft (2) . Check the crankshaft seal and the wear sleeve for the correct installation.End By: Install the flywheel. Refer to Disassembly and Assembly, "Flywheel - Install".
