Use only the approved gear oil in this transfer box.

NOTE:

• Operations for removing output flange are identical to replacing radial shaft seal.

Installation:

Determine and note down measurement A of output flange (previous and new).

Fig. 8: Checking Measurement A

Determine and note down measurement B of output flange (previous and new).

Fig. 9: Checking Measurement B

Determine measurement C, thickness of shim.

Fig. 10: Checking Measurement C

Installation:

Calculate thickness of new shim:

1. Add measurement A of output flange (previous) and measurement C of shim (previous)
   Then subtract measurement B (previous) from result A+C (previous)
2. Subtract measurement B from measurement A of output flange (new)
3. Then subtract result of step 2 from result of step 1.
