Note:
This is a pilot operated relief valve which is
sensitive to adjustment. One complete turn of the
adjusting screw will change the pressure setting
approximately 55 - 69 bar (800 - 1 000 lbf/in
2 ).
6. After the adjustment is completed, tighten jam nut
(12) and replace acorn nut (14).
7. Re-check the pressure to make certain that it did
not change when tightening the jam nut. If the
pressure setting is correct, remove the pressure
gauge and replace plug (67).
8. Check control valve assembly and hydraulic lines
for leaks. Tighten as required.
9. Remove all blocking from road wheels.
MAINTENANCE
Relief valve pressure should be checked on a regular
basis to ensure correct operating pressures are being
maintained. Limited repair of the control valve is with
replacement of parts only.
