6.4.3.9 Task 35. Check and adjustment of wheels toe-in
Adjustment of front wheels toe-in is carried out to prevent the front tires from prema-
ture breakdown.
ATTENTION: CHECK AND ADJUSTMENT OF FRONT WHEELS TOE-IN SHALL
BE CARRIED 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 STEER-
ING JOINTS PLAYS!
To make adjustments, perform the following:
1. Ensure that there is no clearance space in the steering joints, centre bearings
and wheels.
2. Set the front wheels in straight position by way of running the tractor straight
ahead for not less than 3 meters along the horizontal level ground. Engage the parking
break to avoid tractor movement.
3. Measure distance “
А
” (Figure 6.4.30) between rim edges of front wheels 1 and 5
(Figure 6.4.30) on wheel centre level at the front and make visible marks in locations of
measurements.
4. Disengage the parking break, drive the tractor ahead in such a way that the front
wheels turn by half revolution and measure distance “B” between rim edges on wheel cen-
tre level from behind in the point determined and marked before.
5. If the value (“B”-“
А
”) ranges within 0 to 8 mm that means that the toe-in is cor-
rectly adjusted:
а
) leaving the tractor position unchanged, unscrew nuts 2 and 4;
b) rotating steering link tube 3 try to get value (“B”-“
А
”) ranging within 0 to 8 mm;
c) repeat operations, described in subclauses 4 and 5.
d) if value (“B”-“
А
”) falls within the limits of 0 to 8 mm, tighten steering link nuts 2
and 4 with torque of 150 to 170 N·m, leaving steering link length unchanged.
1, 5 – front wheel rim edge; 2, 4 – nut; 3 – regulating tube.
