(1) For installation of seals 113-8432, 113-8433, 175-5290, 197-3889, 569-7728, and 569-7729
(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.
For 3520 engine crankshafts not using the oil fed damper remove the oil plug on the front face of the crankshaft.

Drill three evenly spaced holes in crankshaft front seal (1) and use Tooling (A) to remove crankshaft front seal (1) from the front housing.
Illustration 2 g00659181
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, 113-8433, 175-5290, 197-3889, 569-7728, and 569-7729
Note: The crankshaft rear seal and the wear sleeve must be replaced at the same time. Once the crankshaft rear 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 rear seal and the wear sleeve.
For 3520 engine crankshafts not using the oil fed damper remove the oil plug on the front face of the crankshaft.
Before installation of the crankshaft rear 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.
Inspect the seal and mating hardware for any obvious issues or contamination. Clean any oil that is on the housing.

Small lathe groove only used on 569-7728 Crankshaft Seal and 113-8432 Seal.
Check for the correct sleeve and chamfer direction.
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.
