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

Symptoms of a failing solenoid valve group can include erratic or jerky machine movements, loss of hydraulic power to specific functions, or complete inoperability of controlled systems. If ignored, it can lead to unpredictable machine behavior and potential damage to other hydraulic components. The equipment may become unsafe or impossible to operate.

Installation Tip

Before installation, ensure all electrical connectors are clean and properly seated. Take care not to mix up the hydraulic lines during removal and reinstallation, as this can lead to incorrect function.

Service Note

Inspect the hydraulic fluid for contamination and check the condition of associated hydraulic hoses and fittings.
