1. If a crankshaft wear sleeve is necessary, refer to Step 1a through Step 1d to install the crankshaft wear sleeve. If a crankshaft wear sleeve is not necessary, refer to Step 2.

   1. Clean and polish the crankshaft of imperfections.

   2. Use Tooling (A) to clean the outside diameter of the crankshaft and the inside diameter of the crankshaft wear sleeve.

   3. Apply Tooling (B) to the outside diameter of the crankshaft and the inside diameter of the crankshaft wear sleeve.

   4. 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.
