Failure Symptoms

Initial signs of failure include a slight weeping of hydraulic fluid around the arm cylinder rod. If ignored, the leakage will worsen, potentially leading to a noticeable loss of hydraulic pressure and slower arm movement. Continued operation with failing seals risks internal cylinder damage and reduced machine performance.

Installation Tip

Ensure the cylinder bore and rod are thoroughly cleaned before installation to prevent debris from damaging the new seals. Avoid using excessive force or sharp tools when seating the seals, as this can cause nicks or tears.

Service Note

Inspect the hydraulic fluid for contamination and check the cylinder rod for any signs of wear or damage during seal replacement.
