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 signs of a failing solenoid valve may include intermittent hesitation or sluggish response from engine functions. If left unaddressed, the issue can progress to more consistent performance problems and potential system errors. Continued operation with a faulty valve risks inconsistent power delivery and reduced operational efficiency.

Installation Tip

Ensure the electrical connector is clean and free of corrosion before attempting to connect the new valve. Avoid overtightening the valve body, as this can damage the threads or the sealing surface.

Service Note

Inspect the associated hydraulic filter and fluid for contamination when replacing this solenoid valve.
