To set a required track, do the following:
- brake the tractor using the parking brake. Put wheel chocks at the front and back
of rear wheels;
- jack up the tractor front part (or front wheels one by one), ensuring clearance be-
tween the wheels and the ground;
- to obtain the track by displacing the wheel from one sideboard to the other one
without changing plate position in relation to the rim, unscrew the nuts fastening the wheel
plate to the gear group flange, take the wheels off and change from one sideboard to the
other one,
- to obtain the track by changing plate position in relation to the rim with the wheels
taken off the tractor, unscrew the nuts fastening the wheel rim to the plate, and depending
on the track required, set mutual arrangement of the rim and the plate as shown in the di-
agram in table 4.2.8.
- when mounting the wheels make sure the wheel rotation direction at forward
movement coincides with the direction of an arrow on tyre sidewall.
