Typical example
Apply clean grease to Tooling (A) in order to prevent any swarf that is generated from entering the engine. Use Tooling (A) to drill three evenly spaced holes in crankshaft rear seal (4).
Use Tooling (B) with care in order to remove crankshaft rear seal (4) from flywheel housing (1). Alternate the position of Tooling (B) from one hole to another. Alternating the position of Tooling (B) will allow the crankshaft rear seal to be easily removed from the flywheel housing.
Apply clean grease to Tooling (A) in order to prevent any swarf that is generated from entering the engine. Use Tooling (A) to drill two evenly spaced holes in crankshaft wear sleeve (3).
Use Tooling (B) with care in order to remove crankshaft wear sleeve (3) from crankshaft (2). Alternate the position of Tooling (B) from one hole to the other. Alternating the position of Tooling (B) will allow the crankshaft wear sleeve to be easily removed from the crankshaft.

Sectional view of the crankshaft rear seal, the crankshaft, and the installation tool
Crankshaft rear seal (4) and crankshaft wear sleeve (3) are supplied as a crankshaft rear seal assembly (5) and should not be separated for installation. Note: Do not remove the crankshaft rear seal from the crankshaft wear sleeve.
Use Tooling (D) and follow Step 3.a through Step 3.f in order to install crankshaft rear seal assembly (5).
Position the adaptor of Tooling (D) onto the palm of the crankshaft and secure with bolts.
Position the new crankshaft rear seal assembly (5) over the adaptor onto the rear of the crankshaft.
Align the seal installer of Tooling (D) with the crankshaft. Note: Check that the installer of Tooling (D) is parallel to the adaptor.
Install the nut and washer to the locator.
Tighten the nut until the installer bottoms out on the adaptor in order to install crankshaft rear seal assembly (5) into flywheel housing (1) and onto crankshaft (2).
Remove Tooling (D). End By:
Install the flywheel. Refer to Disassembly and Assembly, "Flywheel - Install" for the correct procedure.
