BMW X5: Replacing Output Flange On Transfer Box At Rear (ATC 700)

IMPORTANT: After completing work, check gear oil level, see Replenishing /Changing Transfer Case Oil (ATC 700) and top up if necessary.

NOTE:

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

Installation:

• Thickness of new shim must be determined before output flange is installed

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

Fig. 16: Checking Measurement A

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

Fig. 17: Checking Measurement B

Determine measurement C, thickness of shim.

Fig. 18: 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.
