   NOTICE
   The use of excessive force on the sleeve distorter can cause the distorter adapter to crack the housing. To help avoid damage to the engine, do not use excessive force to remove the wear sleeve.

3. Insert Tooling (C) between Tooling (B) and wear sleeve (2). Carefully turn Tooling (C) until the edge of the tool causes a crease in wear sleeve (2).

   Repeat this procedure several times around wear sleeve (2) until wear sleeve (2) can be removed by hand.

Installation Procedure

Note: The crankshaft rear seal and the wear sleeve must be replaced at the same time. Once the crankshaft rear seal and the wear sleeve are separated, these components cannot be used again.

Note: Do not use any type of lubricant during the installation of the crankshaft rear seal and the wear sleeve.

1. Before installation of the crankshaft rear 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.

3. Install Tooling (D) on crankshaft (3).

4. Place crankshaft rear seal (1) and wear sleeve (2) onto Tooling (D).

5. Position Tooling (E) onto Tooling (D). Lubricate the face of the washer on Tooling (F). Install Tooling (F) onto Tooling (E). Tighten Tooling (F) until Tooling (E) contacts Tooling (D).
