Adjustments
WARNING
The following adjustments are made with
the engine running. Keep all body parts
and tools away from rotating and hot com-
ponents, and secure all loose clothing.
4. With the body lowered and the FSC in
NEU-
TRAL-PARK,
start the engine. With the en-
gine at normal operating speed, check for
movement of the drive wheels.
5. Lift the body to access the steering adjustment
components.
NOTE:
It may be necessary to tighten the
FSC friction adjustment if the transmissions
are moved out of neutral when the body is
raised. Refer to
Step 7 - Forward Speed
Control Friction Adjustment on page 77
for
location of the FSC friction adjustment nut.
6. Using a wrench on one tracking adjustment
nut, rotate the control rod
clockwise
just until
the wheel on that side begins
to move for-
ward.
Then, counting the turns required,
rotate the control rod
counterclockwise
just
until the wheel stops and then begins
to move
in reverse.
Rotate the control rod back clock-
wise half the number of turns required to make
the wheel go from moving forward to reverse.
The transmission is now centered in the neu-
tral window. Tighten the jam nut on the ball
joint and repeat the same procedure on the
other transmission.
7. Turn off the engine, and then lower the drive
tires onto the ground.
Step 4 -
Full Forward Speed Adjustment
1. Move the FSC to the full
FORWARD
speed
position.
2. Raise the body. The maximum speed tracking
adjustment set screw in both transmission
control arms should not be contacting the limit
stud on the transaxle. If they are, back the set
screws out until they do not touch.
