Installing the differential lock

1.

Fit the selector sleeve (15)

2.

Fit the selector shaft (2) with the shifting fork

(12) and the clutch body (13) to the

differential housing. Make sure that the

tapered edge of the shifting fork is flush

against the shoulder of the axle. Do not fit the

pressure spring yet (1).

3.

Unscrew the adjusting bolt (3) on the

selector shaft (2) so far that when the claws

fully engage, the top of the adjusting screw

remains under the mating surface of the

differential housing with the specified value.

See "Technical data".

Note:

The differential lock must be adjusted such

that the claws of the clutch body and

synchroniser shaft fully engage. In addition,

the shifting fork may not grind against the

edge of the groove in the clutch body. It is

especially important that the play between

crown wheel/pinion gear is properly

adjusted.
