WHEEL TRACK CHANGE
F_02_160
ADJUSTMENT OF TOE-IN OF THE WHEELS OF THE FRONT DRIVING AXLE
Set the wheels symmetrically with the longitudinal axis of the tractor.
At the front on the horizontal plane of the wheel axes measure, in accordance with
fig. F_02_189, the distance between the rims. Mark the place of measurement.
Drive the tractor to move the marked places to the horizontal plane of the wheel
axes at the back (turning by 180°) and measure the distance between the marked
places again.
Release the locking nuts of the heads of the ball screws (2) of connecting rods of
the steering at the hydraulic cylinder.
Adjust the toe-in value by turning the shank of the ball screw (3). Perform the
adjustment of both the joints symmetrically to maintain the same turning radius at
both the sides (perform the measurement at the rim sides).
Tighten the locking nuts of the heads of the ball screws (2) with the torque of 122 -
136 N. The upper surfaces of the heads (1) must be parallel.
