Fig. 5.7.3. Non-driven axle toe-in adjustment
Fig. 5.7.4. Front drive axle toe-in adjustment
5.7.3. Rear wheel track adjustment.
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. 5.7.5).
NOTE:
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
–
244 Nm,
disc to axle hub
–
300
360 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.
