Adjusting the 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. 38) to ensure assembly is properly
seated and operating freely. Correct any discrepancy.
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 11 for an adjustment. If wheel
is not rotating, proceed to step 13. 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. 38). By contrast, tap pump plate
clockwise if wheel is rotating backward (Fig. 38). When
