ADJUSTING FRONT WHEELS
The tractor's front axle consist of three parts; a center
section attached to the tractor's chassis, and two axle
ends which
carry the wheels and slide into the center
section.
To
set the front wheels, use the following procedure:
1. Jack up and securely block the front of the tractor
so
that the axle swings freely. Optional: Jack up
and block one side of the tractor's front axle and
repeat the procedure on the other side of the
tractor.
2.
Remove the 4 bolts holding the axle ends in the
axle center, the
4 bolts on the tie rod clamps, and
the bolt holding the steering cylinder to the axle
center.
3. Slide the axle ends to the desired new setting,
making sure to extend the tie rods the same
amount.
4.
Move the bushing under the steering cylinder to its
new position, and then attach the cylinder, making
surethefrontwheelangle has not changed. (There
is a cylinder mounting hole for each axle position).
5. Replace all bolts and tighten.
6. Check the toe in of the front wheels and adjust
accordingly.
When the axle has been extended to its' maximum
width, a wider tread (maximum) may be obtained by
turning the front wheels around.
NOTE: Make this adjustment only if absolutely neces-
sary.
Do
not use this widest tread position for heavy
front axle loads, such as using a front end loader. This
may
cause severe axle damage.
FRONT
WHEEL
TOE IN
The proper toe-in for this tractor is 3/8"
(1
Omm)
. Always
check the toe-in by measuring the distance between
the inside edges of the front rims at the hub height. The
measurement on the front side of the rims should
be
(3/8"
91
Omm)
less than the measurement on the back
side of the rims. To adjust the toe-in use the following
procedure:
1.
Remove the rod end from the right hand steering
arm.
28
2. Loosen the right hand locknut on the connecting
bar between the two tie rods.
3.
Tum the right hand tie rod to adjust the toe-in.
4. Replace the right hand tie rod end in the steering
arm to check the toe
in
.
5.
When the toe-in is correct, replace the tie rod end
and tighten all nuts. Replace the cotter pin key in
the tie rod end.
NOTE: For DTC tractors, the front wheels should
set with a 3/8" (
1
Omm)
toe-out. This means that the
front wheels should be closer together at the rear,
rather than the front as on the STD.
