WHEEL ALIGNMENT
The front wheels should toe-in approximately 1/8 to
1/4 inch, as measured across dimensions A and B
shown in Figure 6-4.
Figure 6-4
FRONT WHEEL ADJUSTMENT
WARNING: Place the tractor on a firm and
level surface.
To adjust the toe-in, proceed as follows:
1.
Check the steering gear to ensure it is in the cen-
tered position. The hole in the steering segment
gear will align with the hole in the steering housing
(See Figure 6-4).
NOTE:
A 5/16" pin can be used
in the alignment holes to assure the steering seg-
ment is centered.
2.
Mark the front
horizontal
diameter of both front
wheels at the same spot on each wheel-preferably
the inner bead flange of the wheel rims. Mark the
rear horizontal diameter of both front wheels in the
same manner.
3.
Measure the distance between the bottom edges
of the tractor frame channels and the marks on the
front of each wheel (See measurement D in Figure
6-4). These two measurements should be equal.
•
Measure the distance between the frame and the
marks on the rear of each front wheel (See mea-
surement C in Figure 6-4). Measurement D
should be approximately 1/16 to 1/8 inch less
than measurement C on each side of the tractor.
4.
Loosen the jam nuts from the ball joints (See
Figure 6-5).
5.
Disconnect the front ball joints from the steering
arms by removing the hex lock nuts (Refer to
Figure 6-5). Manually move each wheel to achieve
the required toe-in
and
equal D measurements.
Figure 6-5
6.
Making sure not to move the steering gear or either
wheel, turn the ball joint in or out on each drag link
as necessary to align with the hole in each steering
arm.
7.
Reinstall the ball joints in the steering arms and
secure with the hex lock nuts. Tighten the jam nuts
against the ball joints.
PIVOT BAR ADJUSTMENT
WARNING: The tractor should be
checked every 50 hours of operation for
play between the frame axle channel and
the pivot axle.
Check and adjust the pivot axle as follows:
1.
Raise the front of the tractor and set it on jack
stands, so the front wheels are suspended above
the ground.
WARNING: For safety, block the rear
wheels to prevent the tractor from roll-
ing and tipping or sliding the jack
stands.
2.
Pivot the ends of the axle up and down to check for
binding. If the axle is binding, loosen the lock nuts
(See Figure 6-6) until binding is eliminated.
