To set the necessary track by means of re-placing the wheels from one sideboard to
the other, do the following operations:
- brake the tractor using the parking brake. Put wheel chocks at the front and back of
rear wheels;
- jack up the front part of the tractor (or the front wheels, one by one) to provide clear-
ance between the wheels and the ground;
- to form the track, undo the nuts fastening the wheel plate to reduction unit flange,
remove the wheels and re-place to the other sideboard;
- when mounting the wheels, make sure that the direction of wheel rotation coincides
with the direction of the arrow on the tyre sidewall;
Tighten the nuts attaching the wheel to reduction unit flange with a torque of 200 to
250 Nꞏm.
