(1) For installation of seals 113-8432 and 113-8433
(2) For Installation of seals 436-1478 and 436-1479Start By:
Remove the vibration damper.
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.
Illustration 1 g00659180
Drill three evenly spaced holes in crankshaft front seal (1) and use Tooling (A) to remove crankshaft front seal (1) from the front housing.Note: Steps 2 and 3 apply to Seals 113-8432 and 113-8433 only.
Illustration 2 g06043448
Insert Tooling (B) between the front housing and wear sleeve (2).
The use of excessive force on the sleeve distorter can cause the distorter adapter to crack the housing. To help avoid damage to the engine, do not use excessive force to remove the wear sleeve.
Insert Tooling (C) between Tooling (B) and wear sleeve (2). Carefully turn Tooling (C) until the edge of the tool creates a crease in wear sleeve (2).Repeat this procedure several times around wear sleeve (2) until wear sleeve (2) can be removed by hand.Installation Procedure For Seals 113-8432 and 113-8433

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.
Illustration 5 g01207499
Place front seal (1) and wear sleeve (2) onto Tooling (D).
Illustration 6 g01051474
Illustration 7 g01005047
Place Tooling (E) onto Tooling (D). Apply Tooling (J) onto the face of the washer on Tooling (F). Install Tooling (F) onto Tooling (E). Tighten the nut until Tooling (E) contacts Tooling (D).
Remove the Tooling from the crankshaft.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
