Inspections and Adjustments

6. Return the pump to its “neutral” (zero flow) posi-
tion and adjust the pressure limiter setting by
rotating the pressure adjusting screw with the
internal hex wrench.
Clockwise rotation of the pressure adjustment
screw will increase the pressure setting, and
counterclockwise rotation will decrease the pres-
sure setting. Each complete rotation of the pres-
sure adjusting screw changes the pressure set-
ting by approximately 83 bar (1200 psi) on earlier
042 through 100 units, or by approximately 93 bar
(1350 psi) on 030 and later 042 through 100 units.
7. To verify the actual pressure setting, actuate or
move the control input so that the pump again
develops pressure in the high pressure circuit to
the newly adjusted pressure limiter pressure set-
ting, and read the high pressure gauge. Then
allow the pump to return to its “neutral” position.
The pressure in the high pressure circuit should
return to the charge pressure setting.
8. While holding the pressure adjusting screw sta-
tionary, tighten the pressure adjusting screw lock
nut to 3 Nm (26 in•lbf) on early production units, or
16 Nm (12 ft•lbf) on late production units. Do not
over-torque.
9. Shut down the prime mover, remove the gauges
and install the gauge port plugs. Replace the
plastic dust plugs (if used).
The same procedure is used for setting the pressure
limit of the other multi-function valve, but the control
input signal must be activated or moved in the oppo-
site direction so that high pressure develops in the
opposite side of the closed circuit.
