Transmission Control
IMPORTANT: The proper adjustment of the trans-
mission control stops is essential for efficient oper-
ation and life of the transmission. These stops are
properly adjusted at the factory and should only re-
quire readjustment if the transmission or related
control linkage is removed or changed.
NOTE: It would not be unusual for a new machine,
after initial 5 or 10 hours of operation, to begin to not
travel straight (this is due to the break-in of the
transmissions). In this case, proceed to Straight
Ground Travel Adjustment - Step 4.
IMPORTANT: The following adjustment procedures
are sequential. Check and adjust each function in
the order given.
Set Forward Travel Limit (Stop) - Step 1
1. Move the Forward Speed Control (FSC) lever to
the most FORWARD position.
2. Check clearance of the RH and LH steering le-
ver actuator arms with the frame and adjust
forward stop bolt so each lever clears the
frame by at least 1/16 in. (1.6 mm). Clearance
of the arm to the frame should be checked while
applying pressure back on the arm to remove
any slack in the linkage.
3. Tighten the jam nut on the forward travel stop
adjusting bolt.
