Failure Symptoms

Initial signs of pilot valve seal failure include a slight loss of hydraulic system responsiveness or a feeling of 'sloppiness' in the controls. If ignored, this can progress to jerky movements, reduced lifting capacity, and difficulty maintaining precise positioning. Eventually, the pilot system may become unreliable, leading to inefficient operation and potential safety hazards.

Installation Tip

Thoroughly clean the pilot valve bore and spool before installing new seals to prevent contamination. Ensure all seals are correctly oriented and seated to avoid pinching or tearing during assembly.

Service Note

Inspect the pilot hydraulic fluid for contamination and consider replacing the hydraulic filter when servicing the pilot valve.
