3. Earlier production Series 90 pumps are equipped
with a shim adjustable charge pressure relief valve.
Shim kits are available from SAUER-SUNDSTRAND.
Adjustment of charge pressure is accomplished by
removing the plug [1 inch Hex] and changing the shim
thickness behind the spring. The plug for this type of
charge relief valve should be torqued to 68 Nm
(50 lbf•ft).
Later production Series 90 pumps are equipped with
an external screw adjustable charge pressure relief
valve. Adjustment of the charge pressure is accom-
plished by loosening the lock nut -

E 7 6 2 2 0 0 T
and turning the adjustment plug with a large screw-
driver or a 1/2 inch hex wrench.
Clockwise rotation of the plug increases the setting,
and counterclockwise rotation decreases the setting
(at a rate of approximately 3.9 bar (50 psi) per turn).
The lock nut for this type of charge relief valve should
be torqued to 52 Nm (39 lbf•ft).
4. Once the desired charge pressure setting is achieved,
remove the gauges.
