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 indicators of a failing pilot valve include a slight delay in hydraulic response or a feeling of 'stickiness' when operating controls. If ignored, the valve can develop internal leaks or become completely unresponsive, leading to impaired machine control and reduced productivity.

Installation Tip

Thoroughly flush the hydraulic lines connected to the valve before installation to remove any debris that could damage the new valve. Ensure the handle is correctly aligned and secured to prevent premature wear.

Service Note

Inspect the hydraulic fluid and filter for contamination when replacing the pilot valve, as this can indicate other system issues.
