To set a required track, do the following:
- brake the tractor using the parking brake. Put stop members at the front and back of rear
wheels;
- jack up the tractor front part (or front wheels one by one), ensuring clearance between the
wheels and the ground;
- to obtain the track by displacing the wheel from one sideboard to the other one without
changing disk position in relation to the rim, unscrew the retaining nuts of the wheel disk to the
gear group flange, take the wheels off and change from one sideboard to the other one,
- to obtain the track by changing disk position in relation to the rim with the wheels taken off
the tractor, unscrew the retaining nuts of the wheel rim to the disk, and depending on the track re-
quired, set mutual arrangement of the rim and the disk as shown in the diagram in table 3.2.5.
Mounting the wheels make sure the wheel rotation direction at forward movement coincides
with the direction of an arrow on tire side.
The tightening torque for the retaining nuts of disks to the gear group flanges shall make
200 to 250 Nm;
The tightening torque for the retaining nuts of disks to the rim brackets shall make 180 to
240 Nm.
ATTENTION: AFTER MOUNTING THE WHEELS, CHECK THE NUTS FOR TIGHTENING
AFTER THE FIRST OPERATION HOUR, AFTER 10 OPERATION HOURS AND EVERY NEXT
125 HOURS OF OPERATION!
ATTENTION: AFTER CHANGING THE FRONT WHEEL TRACK, CARRY OUT CHECK
AND ADJUSTMENT OF FRONT WHEEL TOE-IN. BEFORE CHECKING TOE-IN, CONTROL
AND, IF NECESSARY, ADJUST THE GAPS IN STEERING JOINTS!
