6.4.3.3 Operation 22. Check/adjustment of clearances in steering joints
To check the backlash and clearances in steering joints 1 (Figure 6.4.16) of the steer-
ing link 4, it is necessary to turn the steering wheel either side when the engine is running.
In case the steering wheel angular play is more than 25° as it’s shown in Figure 6.4.15 the
steering joints play should be eliminated and for this it’s necessary to perform the following
actions:
kill the engine;
remove locking wire 3 (Figure 6.4.16);
screw threaded plug 2 to remove the steering joints play;
locknut plug 2 with wire 3.
If the steering joints play can not be eliminated by tightening of threaded joints, take
the hinge joint to pieces and replace worn-out parts.
Besides, weak tightening of castle nuts 4, 5 of cone-shaped pins may be a reason for
increased steering wheel play angle of HSC hydraulic cylinders.

6.4.3.4 Operation 23. Check and adjustment of wheels toe-in
Adjustment of front wheels’ toe-in is carried out to prevent the front tyres from premature
breakdown.
ATTENTION: CHECK AND ADJUSTMENT OF FRONT WHEELS TOE-IN SHALL BE CAR-
RIED OUT IN EVERY 250 HOURS OF TRACTOR OPERATION, AND AFTER EACH TIME
THE FRONT WHEELS TRACK WIDTH IS CHANGED. BEFORE CHECKING THE FRONT
WHEELS TOE-IN, CHECK AND ADJUST, IF NECESSARY, THE STEERING JOINTS
