(1) For installation of seals 113-8432 and 113-8433
(2) For installation of seals 113-8432 and 113-8433
(3) For Installation of seals 436-1478 and 436-1479Start By:
Remove the flywheel. Refer to Disassembly and Assembly, "Flywheel - Remove and Install".
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 g00659239
Drill three evenly spaced holes in crankshaft rear seal (1). Use Tooling (A) to remove crankshaft rear seal (1).
Illustration 2 g00659240
Insert Tooling (B) between the rear 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 causes 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
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.
Illustration 3 g01136390
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
