Oil Pressure Relief Valve Inspection

•

Check to see if the steel ball [B] inside the valve [A] slides

smoothly when pushing it in with a wooden or other soft

rod, and see if it comes back to its seat by spring [C]

pressure.

NOTE

○

Inspect the valve in its assembled state. Disassembly

and assembly may change the valve performance.

If any rough spot is 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 w ith

compressed air.

WARNING

Clean the oil pressure relief valve in a well

-ventilated area, and take care that there is no

spark or flame anywhere near the working area.

Because of the danger of highly flammable liquids,

do not use gasoline to low-flash point solvent.

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.
