Differential Motor

Differential Motor

Special tools, testers and auxiliary items required

• Torque wrench (VAG 1331)

Removing

If the differential motor (V253) is replaced, observe the following:

The new differential motor is set to a specified position.

- To make installation easier, set this position on the old differential as well, if possible:

- To do this, switch ignition on.





- Rotate transfer case operating unit (E473) to "LOW" position - arrow -.

- Then switch ignition off.

If previous differential motor will be reinstalled, transfer case operating unit (E473) does not need to be set to the "LOW" position.

Continuation for All

- If a shield is fitted over differential motor, remove it.

- Separate connectors - A -, - B - and - C -.





- Remove bracket - D - - arrows -.

- Remove bolts - arrows - and the differential motor from the transfer case.





Installing

If a new differential motor is installed, observe the following:





(Fig.1)

• The transfer case operating unit (E473) is in "LOW" position.





• Shaft with interrupted tooth pattern - 1 - must be in - a - position.

"a = approximately 10 degrees"

- If necessary, set the interrupted tooth pattern - 1 - on the shaft of the differential motor to the position shown in the illustration (e.g. using a screwdriver).

(Fig.2)

• The transfer case operating unit (E473) is NOT in "LOW" position.





• Shaft with interrupted tooth pattern - 1 - must be in - a - position.

"a = approximately 60 degrees"

- If necessary, set the interrupted tooth pattern - 1 - on the shaft of the differential motor to the position shown in the illustration (e.g. using a screwdriver).

Continuation for All

- Make sure that the O-ring - 1 - that seals on transfer case makes contact in base of groove at the differential motor.

- Set differential motor on alignment sleeves - 2 - of transfer case.





- Ensure that the interrupted teeth on differential motor - arrow A - and on selector shaft/transfer case - arrow B - are aligned.

- Insert the bolts - arrows - for the differential motor and tighten.





- Install bracket - D - - arrows -.





- Connect the connectors - A -, - B - and - C -.

- If a shield was fitted over differential motor, install it.

- Check gear oil level in transfer case. Refer to => [ Transfer Case Gear Oil Level, Checking ] Service and Repair.
