Keep all parts clean from contaminants.Contaminants may cause rapid wear and shortened component life.
Note: The crankshaft front seal and the wear sleeve must be replaced at the same time. Once the crankshaft front 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 front seal and the wear sleeve.
Before installation of the crankshaft front 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 to remove any imperfections on the crankshaft.

Clean the outside diameter of crankshaft (3) and the inside diameter of the new wear sleeve (2). Clean the bore for the crankshaft front seal in front housing (4).Apply Tooling (G) to the inner diameter of the wear sleeve and the surface of the crankshaft prior to assembly.
Install Tooling (D) on crankshaft (3).
Place crankshaft front seal (1) and wear sleeve (2) onto Tooling (D).
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).
Remove the Tooling from the crankshaft.
Check the crankshaft front seal and the wear sleeve for the correct installation.Installation Procedure For Seals 436-1478 and 436-1479
Keep all parts clean from contaminants.Contaminants may cause rapid wear and shortened component life.
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 (H), install rear seal (1) as outlined in the following steps:
Install pilot (H1) to the crankshaft and install bolts (H2).
Position rear seal (1) onto pilot (H1).
Install driver (H3) onto the shaft of pilot (H1). Mark driver (H3) at the 12 O' Clock position. Install bearing (H4) and nut (H5).
Tighten nut (H5) until the base of driver (H3) contacts the skirt of pilot (H1). Loosen nut (H5) and rotate driver (H3) 180 degree. Retighten nut (H5) until driver (H3) contacts the skirt of pilot (H1).
Remove Tooling (H).End By:
Install the flywheel.
