equal amounts on both sides of the outer
lever. Hook on the spring 41.

Differential lock operation

2

Insert the levers together with the spring
into the gear housing, lubricate and tighten
shaft 44 to 75 Nm. Make sure the levers are
opposite the holes for the switch and the
piston.

3

Fit the piston 49 and the cover 51 reversed
to keep the piston pressed in.

4

Screw in the set screw 45 so that the
differential lock 39 can be aligned with the
teeth in the planet wheel carrier.

5

Adjust the set screw until there is no play
between the teeth. Turn back the set screw
1/8 turn (45

°

) to attain an axial clearance of

0.20-0.50 mm between the top of the teeth
on the differential lock and the planet wheel
carrier (bottom of the teeth gaps). Insert the
ball 46 and tighten the lock bolt 47.

6

Fit the switch 48.
