The standard factory wheel track is set to 1512 mm.
The wheel track setting of rear wheels is done by the change of rim position and disc with a heave rear part
of a tractor. It is necessary for wheels to spin freely.
Before heaving do not forget to lock the tractor against movement by making front wheels
stable!
After the change of wheel track, tighten all the screws connecting the disc with a rim by a torque of 270 - 300
Nm and nuts of screws connecting a disc with wheel shaft with a torque of 230 - 245 Nm.
Tighten the screws to a prescribed value after every release of foot joint.
After travelling a distance of 100 m with an unloaded tractor retighten the joints again to a prescribed
torque.
After loading the tractor, tighten the joints after 3 Mh.
Retest the tightening of disc nuts and foots of wheel rims after 10 Mh.
Until you travel first 100 Mh, check the disc nuts and foot of front and rear wheels tightening often (at
least 6 times in the first 100 Mh).
Continue retesting the disc nuts and foot rims of front and rear wheels tightening always after working
every 100 Mh.
