prevent the wrench from slipping while pressure is being
applied.

2. See Figure 72. Using the supplied spanner wrench (p/
n 5022853), insert the tip of the wrench into the notch
in the pre-load adjuster. While holding the wrench with
both hands, turn clockwise to decrease the pre-load, turn
counter-clockwise to increase the pre-load. Make sure
that for each pair of shocks (A, B or C, Figure 72) that the
left-hand and right-hand are set to the same amount of
pre-load.
Note: Spanner wrench is located under the seat. Rear tires
must be removed to adjust the rear suspension.

Rear Tire Camber Adjustment

The rubber bushings in the cast A-arms may stretch and wear
with time and adversely affect the angle that the rear tire runs
against the ground.
To evaluate if the rear tire camber should be adjusted, park
the unit on a flat, level surface and view the unit from behind.
If you can visually notice that the top of either rear tire is
angled towards the unit, then the rear tire camber needs to be
adjusted.
To adjust the camber you will need to order and install the
correct amount of camber shims (part number 5100332) for
each tire that needs to be adjusted from your dealer. Shims
should only be installed in even numbered quantities.
To discover how many shims are needed:
1. Park the unit on a flat, level surface such as a concrete
floor. Disengage the PTO, engage the parking brake, turn
the ignition switch to OFF, and remove the ignition key.
2. Place a carpenters square (A, Figure 73) against the rear
tire. The bulge in the sidewall will not allow the square to
contact the bottom outside edge of the tire where it first
contacts the ground.

3. Measure and record the distance from the carpenters
square to the top of the tire (B). Measure and record the
distance from the carpenters square to the bottom of
the tire (C). Subtract the bottom measurement from the
top measurement and reference the chart below for the
number of shims that are needed. If the measurement is
greater than .75" (1,91 cm) contact your dealer.

0.2" (0,51 cm)
0.4" (1,04 cm)

Installing the Camber Shims
1. Park the unit on a flat, level surface such as a concrete
floor. Disengage the PTO, engage the parking brake, turn
the ignition switch to OFF, and remove the ignition key.
2. Jack up the rear of the machine and secure with jack
stands. Remove the rear tire.
3. Loosen but do not remove the two (2) 1/2-20 X 3" bolts
(A, Figure 74) and the (2) 1/2-20 X 1-3/4" bolts (B).
