4.2.10 Rear wheel twinning

With an aim to improve gripping properties of the tractor when coupled with heavy
agricultural implements on soils with low bearing capacity, rear wheel twinning with use of
spacers is provided.
The additional wheels are mounted one by one, in the following way:
- set a permissible track for the main rear wheels, as specified in subsection 4.2.9
"Rear wheel track formation";
- put stops under the front and the rear wheels;
- jack up the tractor rear part;
- unscrew the nuts fastening the right and the left rear wheels to the hub and put
them aside;
- put washers 2, included into the spacer kit, on bolts 1 (figure 4.2.4);
- secure the inner wheel with special bolts 3, included into the spacer kit, with a
torque of 700 to 750 N·m;
- mount a spacer on special bolts and tighten it with nuts 4 with a torque of 700 to
750 N·m;
- mount an additional (outer) wheel on the spacer and tighten nuts 5, which were
previously used to fasten the main wheel, with a torque of 700 to 750 N·m;
- mount the other supplementary wheel by analogy;
1 – hub bolt; 2 – washer; 3 – special bolt; 4 – nut; 5 – wheel nut.
