Install adapter (3) on Tool (A).
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.
Place crankshaft seal (2) and wear sleeve (1) on adapter (3). Ensure that the lip of the seal is facing upward.
Install the O-ring seal on adapter (3).
Install Tool (B) on the studs of Tool (A). Install Tool (C) and tighten evenly until the seal is against the bottom of the adapter bore.
Remove Tools (C), (B), and (A) from adapter (3).
Clean the outer surface of the crankshaft with 169-5464 Quick Cure Primer.
Place clean engine oil on the O-ring seal and install the seal on adapter (3). Apply 4C-9507 Retaining Compound to the outside diameter of the crankshaft and to the inside diameter of the wear sleeve.

Install Tool (D) on the end of the crankshaft.
Install Tool (E) in the drive housing. Place adapter (3) on Tool (E) and (D). Ensure that the wear sleeve makes contact with the end of the crankshaft.

Install Tool (B) over the outside diameter of Tool (F) until Tool (B) is against the shoulder of Tool (F).
Install Tool (B) and (F) on Tool (E).
Apply 1P-0808 Multipurpose Grease on the face of Tool (G). Install Tool (G) on Tool (D). Tighten Tool (G) until the wear sleeve and the adapter are in the correct position.
Remove the Tools from the engine.

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 (J), install front seal (1) as outlined in the following steps:
Install pilot (J1) to the crankshaft and install bolts (J2).
Position front seal (1) onto pilot (J1).
Install driver (J3) onto the shaft of pilot (J1). Mark driver (J3) at the 12 O' Clock position. Install bearing (J4) and nut (J5).
Tighten nut (J5) until the base of driver (J3) contacts the
