1

 Place dial indicator (2) with  dial indicator holder (3) on the axle drive housing (1) such that the tip of the dial indicator makes slightly pressurized contact with a tooth of the crown gear (5).

2

Set scale of  dial indicator (2) to 0.

3

Move crown gear (5) forward and backward and when doing so, read off the gear backlash on the  dial indicator (2). 

4

Carry out operation steps 1 to 3 on two further teeth.

5

Adjust gear backlash by uniformly turning both threaded rings (4) with the  square drift. 

 By uniformly turning the threaded rings (4), the crown gear, without tensioning the tapered roller bearings, is moved in the desired direction.

6

Mark installation position of differential-side threaded ring (6) relative to bearing bracket (7).

7

Turn in differential-side threaded ring (6) with  square drift clockwise by 2 teeth.

8

Check gear backlash again and adjust if necessary.

9

 Remove dial indicator (2) with  dial indicator holder (3) from axle drive housing (1).
