Keep all parts clean from contaminants.Contaminants may cause rapid wear and shortened component life.
Note: Wear sleeves are used to reclaim worn seal surfaces or damaged seal surfaces. Wear sleeves are not original equipment. The wear sleeve is supplied with a crankshaft rear seal that has a larger internal diameter than a standard crankshaft rear seal. A standard crankshaft rear seal cannot be used if a wear sleeve is installed.
Ensure that the crankshaft is thoroughly clean and dry. Remove any areas of raised damage.
Lubricate the inner surface of the crankshaft wear sleeve with clean engine oil.

Use Tooling (A) and Tooling (B) to install the crankshaft wear sleeve, as follows:
Align Tooling (B) with the dowels in crankshaft (2) and install Tooling (B) to the crankshaft. Ensure the correct orientation. Note: Verify that Tooling (A) will slide freely over Tooling (B).
Carefully slide crankshaft wear sleeve (1) over Tooling (B) until the crankshaft wear sleeve contacts the rear of crankshaft (2).
Assemble Tooling (A) to Tooling (B) and install the bolt and the washer. Ensure that the face of Tooling (A) with the deep counterbore is toward crankshaft wear sleeve (1).
Tighten the bolt until Tooling (A) bottoms out on Tooling (B) in order to pull crankshaft wear sleeve (1) onto crankshaft (2).
Remove Tooling (A) and Tooling (B). End By:
Install the new crankshaft rear seal that was supplied with the crankshaft wear sleeve.
