SECTION 2 - OPERATION
2-125
REAR WHEEL TRACK ADJUSTMENT
Adjustment of track spacing is achieved by sliding the
complete wheel assembly on the axle shaft and/or by
changing the rim and disc position.
To reposition the wheel on the axle shaft or to
completely remove the wheel, block the front wheels,
front and rear, jack up the rear of the tractor until both
rear wheels are off the ground. Support the rear of the
tractor with blocking or stands. Position wheels with
hole in the rim at the top.
Loosen the two center wedge bolts, 1, about 12 mm
(1/2″). Remove the four outer wedge bolts, 2.
184
Clean the bolts and threaded holes in the wedges
before lubricating and installing the outer wedge
bolts at 1, for pushing the wedges. Tighten the outer
wedge bolts evenly until the wedges loosen on the
axle shaft. The wheel assembly will now be free to
slide in or out on the axle shaft.
IMPORTANT: Do not use a torque greater than 407
N·m (300 ft.-lbs.) on the pusher bolts. The use of
penetrating oil between the wedge and axle shaft will
be of benefit. If difficulty is experienced, place a shaft
protector over the end of the axle shaft and strike with
a hammer to “shock” the wedge free.
WARNING
Take suitable precautions, including the use of
safety glasses, against the possibility of flying
metal particles.
