Adjusting the Front Wheel
Alignment
Service Interval:
Every 100 hours/Yearly (whichever
comes first)—Check the front wheel
camber and toe-in.
Preparing to Adjust Camber or
Toe-in
1.
Check the tire pressure to ensure that the front
tires are inflated to 82 kPa (12 psi).
2.
Either add weight to the driver's seat equal to
the average operator who will run the machine,
or have an operator sit on the seat. The weight
or operator must remain on the seat for the
duration of the adjustment procedure.
3.
On a level surface, roll the machine straight back
2 to 3 m (6 to 10 ft) and then straight forward
to the original starting position. This allows the
suspension to settle into the operating position.
Adjusting the Camber
Owner provided tools:
spanner wrench, Toro Part
No. 132-5069; refer to your authorized Toro distributor.
Important:
Make the camber adjustments only
if you are using a front attachment or if there is
uneven tire wear.
1.
Check the camber alignment at each wheel; the
alignment should be as close to neutral (zero)
as possible.
Note:
The tires should be aligned with the tread
evenly on the ground to reduce uneven wear.
2.
If the wheel camber is out of alignment, use the
spanner wrench to rotate the collar on the shock
absorber to align the wheel (
).

Adjusting the Front Wheel Toe-in
Important:
Before adjusting toe-in, ensure that
the camber adjustment is as close to neutral as
possible; refer to
Adjusting the Camber (page 46)
.
1.
Measure the distance between both of the front
tires at the axle height at both the front and rear
of the front tires (
).

If the measurement does not fall within 0 to
6 mm (0 to 1/4 inch), loosen the jam nuts at the
outer end of the tie rods (
).

Tighten the tie rod jam nuts when the adjustment
is correct.
5.
Ensure that there is full travel of the steering
wheel in both directions.
