9.2.3 Charge Relief Valve
The pump charge relief valve may be shim adjustable
(early models) or screw adjustable (late models).
1. Remove the shim adjustable charge relief valve
plug with a 1 inch hex wrench.
Before removing the screw adjustable relief valve
plug, mark the plug, lock nut, and housing so as
to approximately maintain the original adjust-
ment when assembling. Remove the screw ad-
justable charge relief valve plug by loosening the
lock nut with a 1–1/16 inch wrench for 030 through
100 units or a 1-5/8 inch for 130 through 250
units. Unscrew the plug with a large screwdriver
or 1/2 inch hex wrench.
2. Remove the spring and relief valve poppet.
3. Inspect the poppet and mating seat in the end cap
for damage or foreign material.
When inspecting shim adjustable valves, do not
alter the shims or interchange parts with another
valve.
4. Install the poppet and spring. For shim adjustable
valves, install the plug and torque to 68 Nm (50
ft•lbf). For screw adjustable valves, install the
plug with its lock nut, aligning the marks made at
disassembly, and torque the lock nut to 52 Nm
(38 ft•lbf).
Check the charge pressure and adjust, if necessary
(8.1.1).
9.2.2 Pressure Override Valve (Option
for 180 Frame Size)
1. Remove the four screws attaching the pressure
override valve to the pump end cap with a 5 mm
internal hex wrench. Remove the O-rings.
2. Inspect valve for damage to parts.
3. Install new O-rings. Install the valve onto the
pump end cap and torque the screws to 16 Nm
(12 ft•lbf).
