Installation & Application Notes

Inspect mating surfaces for wear before fitting. Use torque specs from service manual. Replace gaskets and seals as a set — reusing compressed gaskets causes oil leaks. Clean all oil passages with compressed air.

Always consult the OEM service manual for model-specific torque values and procedures. WhatsApp our technical team if you need fitment guidance.

Failure Symptoms

Early indications of a failing relief valve may include a persistent low hydraulic pressure or a noticeable increase in hydraulic fluid temperature. If ignored, the system's ability to maintain optimal operating pressure will degrade, leading to reduced performance and potential overheating. This can result in significant downtime and increased wear on other hydraulic components.

Installation Tip

Before installing, thoroughly flush the hydraulic system to remove any contaminants that could lodge in the new valve. Ensure the valve is installed in the correct orientation as per the service manual to guarantee proper flow and pressure regulation.

Service Note

Inspect the hydraulic filter and fluid for signs of contamination or degradation, and check all associated hydraulic lines and fittings for leaks.
