Adjustments

Adjust Traction Pedal for Neutral

The piston (traction) pump control lever should return to
the neutral position when the traction pedal is released.
If the machine creeps when in neutral, check the follow-
ing items:
1. The centering arms should be parallel to each other
and also parallel to the centerline of the machine.
2. The centering arms should touch both front and rear
bearings on control plate.
3. The centering arms should be tensioned by two
springs.
4. The bearings attached to control plate should rotate
freely.
Reposition the control plate on the piston pump control
lever if needed.

Adjust Relief Valve

The spray pump drive circuit relief valve is located on the
left side of the piston (traction) pump (Fig. 24). The
steering circuit relief valve is located under the suction
hose on the right side of the gear pump (Fig. 25). Relief
pressure should be tested before and after adjusting the
relief valve (see Steering Circuit Relief Pressure Test
and Spray Pump Drive Circuit Relief Pressure Test in the
Testing section of this chapter). Adjustment of the relief
valve can be performed as follows:
NOTE: Do not remove the relief valve for adjustment.
NOTE: To gain access to the adjustment socket and
jam nut on the steering circuit relief valve, remove plastic
cap.
1. To increase relief pressure setting, loosen jam nut
on relief valve and turn the adjustment socket on the re-
lief valve in a clockwise direction. A 1/8 turn on the sock-
et will make a measurable change in relief pressure.
Tighten jam nut after adjustment.
2. To decrease pressure setting, loosen jam nut on re -
lief valve and turn the adjustment socket on the relief
valve in a counterclockwise direction. A 1/8 turn on the
socket will make a measurable change in relief pres-
sure. Tighten jam nut after adjustment.
3. Recheck spray pump drive circuit relief pressure and
readjust as needed.
