3. Tighten the jam nut on the forward travel stop
adjusting bolt.
Forward Speed Control Stop
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 le-
ver actuator until end play develops between
the lever actuator and the adjustment nut (slid-
ing 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 tight-
en 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 adjust-
ment nut is too tight (preferred condition), the max-
imum 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 move-
ment of the drive wheels.
NOTE: If the engine will not start, check and ad-
just the neutral safety switch (see item 4 below).
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 Ad-
justment 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 er-
ror” 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 for-
ward 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). Slight adjustments can be made by
carefully bending the leaf switch up or down as
needed. Refer to adjustment description for
Safety Switches in this section.
