and Steering Lever Adjustment
Steering Lever End Play Adjustment - Step 2
1. Position the FSC lever to the most FORWARD
position.
2. Loosen the adjustment nut on each steering lever
actuator until end play develops between
the lever actuator and the adjustment nut (sliding
on transmission control rod).
3. Hold the actuator back as shown (against the
spring pressure) and tighten the nut to the point
where the end play is removed and then tighten
two additional turns.
IMPORTANT: If the adjustment nut is too loose
(end play exists) excessive loads are placed on
transmission internal control stops. If the adjustment
nut is too tight (preferred condition), the maximum
forward travel speed is reduced.
Neutral Function Adjustment - Step 3
1. Move the FSC lever to the NEUTRAL-PARK
position (rear travel limit).
2. Start the engine (operate first at idle and then
normal operating speeds) and check for movement
of the drive wheels.
Neutral Function Adjustment
3. If drive wheels are moving, stop the engine and
adjust the FSC neutral stop by adjusting the
FSC actuator clevis (see Neutral Function Adjustment
photo for clevis location). If the drive
wheels are moving backward, remove the cotter
pin and clevis pin and screw the clevis forward.
If the drive wheels are moving forward, screw
the clevis backward. Restart the engine and
check for wheel movement (several “trial and error”
adjustments may be required). At this point
it may not be possible to adjust both wheels
stationary since the differential adjustment has
not been made. (This is covered by the Straight
Ground Travel Adjustment - Step 4.) In this
case, the neutral adjustment should be made for
one wheel stationary and the other moving forward
slightly.
4. Check and adjust the neutral safety switch
for closure and function with the FSC in neutral
(the engine will not start when the switch is
open). Use panel nuts on the switch body to
adjust switch position for closure in neutral. Refer
to adjustment description for Safety Switches
in this section.
NOTE: If the engine will not start, check and adjust
the neutral safety switch (see item 4 below).
