Keep all parts clean from contaminants.Contaminants may cause rapid wear and shortened component life.
Every time that the crankshaft seal is removed from the wear sleeve, a new wear sleeve and crankshaft seal must be installed.

Attach Tooling (D) to the crankshaft.
Clean the outer diameter of the crankshaft and the inner diameter of the new wear sleeve with Tooling (G).
Apply Tooling (H) to the outer diameter of the crankshaft and the inner diameter of the new wear sleeve.
If the crankshaft seal and the wear sleeve come apart during installation, the crankshaft seal and the wear sleeve must be replaced.
Note: The front crankshaft seal and the wear sleeve cannot be interchanged with the rear crankshaft seal and the wear sleeve.
Do not place engine oil on the crankshaft seal for installation. Lubrication of the crankshaft seal can give a false indication of leakage at a later time.

Do not place engine oil on the crankshaft seal for installation. Lubrication of the crankshaft seal can give a false indication of leakage at a later time.
Note: Ensure that there are no imperfections on the mating surfaces of the crankshaft, the installation tooling, or on the sealing surface of the crankshaft. Surface imperfections can distort the seal during installation and will cause the seal to malfunction.

Using Tooling (K), install rear seal (1) as outlined in the following steps:
Install pilot (K1) to the crankshaft and install bolts (K2).
Position rear seal (1) onto pilot (K1).
Install driver (K3) onto the shaft of pilot (K1). Mark driver (K3) at the 12 O' Clock position. Install bearing (K4) and nut (K5).
Tighten nut (K5) until the base of driver (K3) contacts the skirt of pilot (K1). Loosen nut (K5) and rotate driver (K3) 180 degree. Retighten nut (K5) until driver (K3) contacts the skirt of pilot (K1).
Remove Tooling (K).End By:
Install the flywheel.
