TRACTION DRIVE MAINTENANCE

ADJUSTING TRACTION CONTROL ROD

1. Check traction drive neutral position to assure front
wheels do not creep; refer to Adjusting Traction Drive for
Neutral.
2. Press down on front of traction pedal and check
travel. There should be approximately 3.50" clearance
between end of pedal and floor plate when pedal in fully
depressed (Fig. 39). Adjust pump control rod (Fig. 40)
to attain dimension.

ADJUSTING TRACTION PEDAL FRICTION
WHEEL
1. Loosen two nuts securing traction pedal shaft on
right side of pedal (Fig. 40).
2. Rotate shaft to relocate worn surface of friction
wheel away from underside of traction pedal.
3. Tighten nuts to secure shaft and wheel in position.
ADJUSTING TRACTION DRIVE FOR
NEUTRAL
1. Park vehicle on a level surface and turn engine off.
Apply the parking brake, tip seat forward, and actuate
pump lever (Fig. 41) to insure assembly is properly
seated and operating freely. Correct any discrepancy.
Figure 41
2. Block right front tire and both rear tires so vehicle
cannot roll forward or backward.
3. Jack up frame so left front wheel is off the shop floor.
Use a jack stand to support the frame.
4. Start engine and allow it to idle for 5 minutes to heat
oil in transmission to operating temperature.
5. Release parking brake; then check left front wheel
that is off shop floor. Wheel must not be rotating. If wheel
is rotating, proceed to step 6 for an adjustment. If wheel
is not rotating, proceed to step 8. Verify the adjustment
with throttle in SLOW and FAST position.
6. Because the wheel is rotating, the pump plate must
be adjusted. But before adjusting the pump plate, move
throttle to SLOW. If wheel is rotating forward, loosen
capscrews, and lightly tap bottom of pump plate
counterclockwise (Fig. 41). By contrast, tap pump plate
clockwise if wheel is rotating backward (Fig. 41). When
wheel stops rotating, tighten capscrews holding pump
plate against side of transmission. Verify the adjustment
with throttle in SLOW and FAST position.
