1. Traction adjustment cam
The engine must be running so a final adjustment
of the traction adjustment cam can be performed.
Contact with hot or moving parts can result in
personal injury.
Keep hands, feet, face, and other body parts away
from the muffler, other hot parts of the engine, and
other rotating parts.
Warning
4. Start the engine and rotate the cam hex in both
directions to determine the mid position of the neutral
span.
5. Tighten the locknut securing the adjustment.
6. Stop the engine.
7. Remove the support blocks and lower the machine to
the shop floor. Test drive the machine to make sure it
does not move when the traction pedal is in neutral.
8. After adjusting the pump plate, check the neutral switch
operation and adjust, if necessary.
Adjusting Neutral Switch
Whenever the pump plate is adjusted, check the neutral
switch (Fig. 57) operation and, if necessary, adjust it as
follows:
1. Park the machine on a level surface and turn the engine
off.
2. Loosen the locknut securing the switch adjusting screw.
Thread it away from the switch until the capscrew head
clears the switch.

3. Adjust switch location until circuit is made when in
neutral and broken with 1 inch travel of traction pedal.
4. Tighten the locknut
Adjusting the Belts
Make sure the belts are properly tensioned to ensure proper
operation of the machine and prevent unnecessary wear. On
new belts, check the tension after 8 hours operation.
Hydraulic Pump Belt
A new hydraulic pump belt should be tensioned so that it
deflects 0.12 inch with a 15–17 pound load applied midway
in the span of the belt. A used belt should be tensioned so
that it deflects 0.12 inch with a 11–13 pound load applied
midway in the span of the belt.
Tighten the nut on the adjustment rod (Fig. 58) until the
desired belt tension is attained.
Note: Tighten the belt to eliminate slippage (squealing
under load) but do not overtighten.
