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 engine
at normal operating speed, check for movement
of the drive wheels.
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
later in this section for location of the
FSC friction adjustment nut.
5. Using a wrench on one tracking adjustment nut,
rotate the control rod
counterclockwise
just
until the wheel on that side begins
to move for-
ward.
Then, counting the turns required, rotate
the control rod
clockwise
just until the wheel
stops and then begins
to move in reverse.
Ro-
tate the control rod back counterclockwise half
the number of turns required to make the wheel
go from moving forward to reverse. The trans-
mission is now centered in the neutral window.
Tighten the jam nut on the ball joint and repeat
the same procedure on the other transmission.
6. Turn off the engine, and then lower the drive
tires onto the ground.
