3.2.9.1 Track formation of rear wheels mounted on terminal hubs
The rear wheel track with the wheels of basic configuration 18.4R34 is changed by
moving the hub together with the wheel over the axle shaft and by re-placing the wheels
from one sideboard to the other one as shown in figure 3.2.6.

ATTENTION: EX-WORKS DELIVERED REAR WHEELS ARE SET TO A TRACK UNDER
THE VARIANT A (FIGURE 3.2.6)!
To change the rear wheel track perform the following operations:
- put the tractor on a level ground, put the stops under the front and rear wheels,
clean the axle shafts from dirt;
- jack up the corresponding axle tube;
- undo the nuts 1 (Figure 3.2.7) attaching the wheels and remove the wheels;
- release four bolts 2 of the rear wheel hubs by 3…5 turns;
- move the hub to one or other side to obtain the required width;
- tighten the four bolts 2 attaching the hub; tighten them evenly, one by one, in a
criss-cross pattern. The final bolts 2 tightening torque is 300-400 N·m;
- mount the wheel and tighten the nuts 1 with a torque of 300 to 350 N·m;
- repeat the operations on the opposite wheel.
1 – nuts attaching the wheel to the hub; 2 – bolts attaching the hub to the axle shaft.
