5.4.3.3 Operation 33. Check / adjustment of front wheel toe-in
Adjustment of front wheel toe-in is carried out to prevent front tires from premature
breakdown.
ATTENTION: CHECK AND ADJUSTMENT OF FRONT WHEEL TOE-IN SHALL BE
CARRIED OUT AFTER EVERY 250 HOURS OF TRACTOR OPERATION, AND AFTER
EACH TIME THE FRONT WHEEL TRACK WIDTH IS CHANGED. BEFORE CHECKING
FRONT WHEEL TOE-IN, CHECK AND ADJUST IF NECESSARY, THE STEERING JOINT
CLEARANCES!
To make necessary adjustments, do the following:
1. Make sure there are no clearance gaps in hinges of the steering mechanism of the
pivot supporting block bearings and wheels.
2. Set front wheels into straight position corresponding to the direct tractor movement
for which drive the tractor on hard flat surface for not less than 3 meters and stop. Engage
the parking brake to avoid tractor movement.
3. Measure distance "А" (Figure 5.4.22) between edges at the height of wheel cen-
ters, and make visible marks in the measured places.
4. Disengage the parking brake, drive the tractor forward so that front wheels turn by
half revolution and measure distance "B" between wheel edges at the height of wheel cen-
ters at the back in the marked points.
5. If the value ("B"-"А") is within 0 to 8 mm that means the toe-in is correctly adjusted.
If the value ("B"-"А") is below 0 or more than 8 mm, do the following:
а) leaving the tractor position unchanged, unscrew lock nuts 1 and 3;
b) rotating steering link tube 2, try to get the value ("B"-"А") within 0 to 8 mm;
c) repeat the operations described in sub-points 3 and 4.
d) if the value ("B"-"А") is within the limits from 0 to 8 mm, tighten steering link lock
nuts 1 and 3 with a torque from 100 to 140 Nm, leaving the steering link length unchanged.
