Inspections and Adjustments
This section offers instruction on how to perform inspections and adjustments on pump and motor components. Read
through the entire related section before beginning a service activity. Refer to the corresponding section for location of
gauge ports and suggested gauge size.

Charge Pressure Relief Valve Adjustment
The following procedure explains how to check and adjust
the charge pressure relief valve.
* This is the actual charge pressure port gauge reading minus
the case pressure port gauge reading.
Note:
These pressures assume a pump speed of
1450 - 1500 rpm. At higher pump input speeds
(with higher charge flows) the charge pressure
will rise over the rated setting.
WARNING
The following procedure may require the vehicle/
machine to be disabled (wheels raised off the ground,
work function disconnected, etc.) while performing
the procedure in order to prevent injury to the
technician and bystanders. Take necessary safety
precautions before moving the vehicle/machine.

1.
To measure pump charge pressure, install a pres-
sure gauge in the pump charge pressure gauge port
(M3). Also install a gauge to measure case pressure
(tee into L1 or L2 or use servo gauge port). Operate
the system with the pump in “neutral” (zero displace-
ment) when measuring pump charge pressure.
2.
The table shows the acceptable pump charge pres-
sure range for some nominal charge relief valve
settings (see sample model code at right). These
pressures assume 1500 pump rpm and a reservoir
temperature of 50°C (120°F ), and are referenced to
case pressure (see footnote on next page). Smaller
displacement charge pumps will produce charge
pressure readings in the lower portion of the range,
while larger displacement charge pumps will produce
readings in the higher portion of the range.
