Kawasaki Ninja Service Manual / Engine Lubrication System / Oil Pressure Relief Valve / Oil Pressure Relief Valve Inspection

Remove the oil pressure relief valve (see Oil Pressure Relief Valve Removal).
Check to see if 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 [B] pressure.

Oil Pressure Relief Valve Inspection

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 relief valve in a well-ventilated area, and take care that there is no spark or flame anywhere near the working areas. Do not use gasoline or low flash-point solvents to clean the 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 replacement of individual parts.
