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.

4.

Fit the pressure spring (1) between the 

differential housing and the shifting fork (12).

5.

Fit the sealing ring (5) to the piston of the 

differential lock and lightly oil the piston.

6.

Fit the piston (6) into the cylinder.

7.

Fit the air connection at the correct position. 

The air connection lip must point to the top of 

the differential in the direction of the input 

shaft.
