Rear wheel track adjustment is effected by changing the position of the wheel rim in relation to the
disc and/or of the disc in relation to the axle hub as well as by reversing the wheels and
interchanging them. There are six possible settings (Fig. 5.7.3).

If the wheels are reversed, they must be transferred to the opposite sides of the
tractor so as to maintain the correct direction of the tyre tread.
When refitting or adjusting a wheel, tighten the nuts/bolts progressively to the following torque:
rim to disc
–
176 Nm,
disc to axle hub
–
270 Nm
.
WARNING:
!
Recheck after driving the tractor 200 m and then twice at 10 hour interval. If heavy
work is involved, check twice at 2 hour interval until torque is held according to the
values as given above.
