MAINTENANCE AND STORAGE
should reach mid-stroke (4.4”/11.2 cm).
Once both cylinders are at 4.4”/11.2 cm, Toe-
In can be set.
To Phase the Steering Cylinders
1. Start the machine.
2. Turn steering wheel to the right or left.
3. When the wheels stop turning, continue
to turn the steering wheel 3 to 4 full revo-
lutions (this will put the cylinders back in
phase with each other).
Step 2 - Set Toe-In
Front Wheels
•
.25” (.6 cm) Toe-In per side/0.5” (1.3 cm)
total Toe-In
Rear Wheels
•
0” (0 cm) Toe-In/Out
To Set Toe-In
1. Deflate the air bags.
NOTE: Refer to “Air Suspension Exhaust”
provided in the Miscellaneous
Section elsewhere in this manual for
further information.
2. Measure the distance from the ground to
center of wheel hub.
NOTE: All four wheel hubs should measure
the same distance.
3. Mark this distance on the inner edge of
the wheel rim (front and back of each rim
- 8 marks total).
NOTE: All measurements will be taken from
these markings.
4. Visually align the tires from front to rear.
Front Wheels
5. Measure the width between the front
wheels (front W1, rear W2) at the wheel
hub center line and record measure-
ments.
6. Adjust the wheels until the front and rear
measurements are equal (W1=W2).
7. Measure diagonally (D1 and D2) and
record the measurements.
8. Adjust the wheels until the measure-
ments are equal.
9. Continue to cycle between Steps 5-6 and
7-8 until the width measurements match
and the diagonal measurements match.
Then and only then are the wheels paral-
lel to each other and the frame.
NOTE: To achieve this, both conditions must
be met.
NOTE: The front steering cylinders must
both be centered before
proceeding!
10. Set both cylinders to center by measur-
ing 7.64” (19.4 cm) (as shown in the fol-
lowing photo).
The position sensors should both read
4.4” (11.2 cm) when the cylinders are
centered and in phase.
This is not required for All-Wheel
Steer (AWS) machines, as the cylinder
position sensors can be used to cen-
ter the cylinders.
•
The cylinder sensors must be calibrated
for this position to be accurate.
•
If the cylinders do not center at this mea-
surement, they are not in phase. To re-
phase the cylinders, turn the steering
wheel so that one cylinder is fully
retracted and the other is fully extended.
Turn the steering wheel at least one full
