Oil Pressure Relief Valve Inspection
•
Check to see if the valve [A] slides smoothly when push-
ing it in with a wooden or other soft rod, and see if it comes
back to its seat by spring [B] pressure.
NOTE
○
Inspect the valve in its assembled state. Disassembly
and assembly may change the valve performance.
If any rough spots are found during above inspection,
wash the valve clean with a high flash-point solvent and
blow out any foreign particles that may be in the valve with
compressed air.
WARNING
Gasoline and low flash-point solvents can be
flammable and/or explosive and cause severe
burns. Clean the oil pressure relief valve in a
well-ventilated area, and take care that there are no
sparks or flame anywhere near the working area;
this includes any appliance with a pilot light. Do
not use gasoline or a low flash-point solvent to
clean the oil pressure relief valve.
If cleaning does not solve the problem, replace the oil
pressure relief valve as an assembly. The oil pressure
relief valve is precision made with no allowance for re-
placement of individual parts.
