OSCILLATING AXLE COMPONENTS
14-2
Oscillate Directional Valve
How to Adjust the Oscillate
Relief Valve Pressure
1 Connect a 0 to 2000 psi / 0 to 150 bar pressure
gauge to the diagnostic nipple located on the
function manifold.
2 Remove the drive chassis cover from the non-
steer end of the machine.
3 Disconnect the directional valve linkage, by
removing the clevis yoke from the drive
chassis. Refer to illustration 1.

4 Start the engine from the ground control.
5 With the engine running, manually activate the
valve and observe the pressure reading on the
pressure gauge. Refer to Section 2,
Specifications.
6 Turn the engine off.
7 Locate the relief valve on the function manifold
(item SC).
8 Loosen the jam nut on the relief valve.
9 Turn the valve clockwise to increase the
pressure or counterclockwise to decrease the
pressure.
Tip-over hazard. Do not adjust the
relief valve higher than specified.
10 Tighten the jam nut.
11 Repeat steps 4 through 10 to confirm the
oscillate relief valve pressure.
Note: The oscillate pressure required is while the
oscillate cylinders are in motion. Do not dead head
the cylinders to either side.
12 Turn the engine off, remove the pressure gauge
and assemble the directional valve linkage.
13 Install the cover on the non-steer end of the
drive chassis.
