Adjust Relief Valve<br />
The spray pump drive circuit relief valve is located on the<br />
left side of the piston (traction) pump (Fig. 26). The<br />
steering circuit relief valve is located under the suction<br />
hose on the right side of the gear pump (Fig. 27). Relief<br />
pressure should be tested before and after adjusting the<br />
relief valve (see Steering Circuit Relief Pressure Test<br />
and Spray Pump Drive Circuit Relief Pressure Test in the<br />
Testing section of this chapter). Adjustment of the relief<br />
valve can be performed as follows:<br />

NOTE: Do not remove the relief valve for adjustment.<br />
NOTE: To gain access to the adjustment socket and<br />
jam nut on the steering circuit relief valve, remove plastic<br />
cap.<br />
1. To increase relief pressure setting, loosen jam nut<br />
on relief valve and turn the adjustment socket on the relief<br />
valve in a clockwise direction. A 1/8 turn on the socket<br />
will make a measurable change in relief pressure.<br />
Tighten jam nut after adjustment.<br />
2. To decrease pressure setting, loosen jam nut on relief<br />
valve and turn the adjustment socket on the relief<br />
valve in a counterclockwise direction. A 1/8 turn on the<br />
socket will make a measurable change in relief pressure.<br />
Tighten jam nut after adjustment.<br />
3. Recheck spray pump drive circuit relief pressure and<br />
readjust as needed.<br />
