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

Initial symptoms of a failing solenoid valve may include sluggish or jerky hydraulic movements, such as boom or bucket operation. If the valve becomes stuck, it can lead to a complete loss of hydraulic function in the affected circuit. Continued operation with a faulty valve risks overheating the hydraulic system and damaging other components.

Installation Tip

Ensure the hydraulic system is properly depressurized before attempting removal to prevent injury and fluid loss. Make sure the new valve is installed in the correct orientation as per the service manual.

Service Note

Clean or replace the hydraulic filter and inspect hydraulic fluid for contamination when servicing the solenoid valve.
