Failure Symptoms

Early indications of a failing stick cylinder include a gradual loss of lifting capacity or the inability to hold a specific position under load. If ignored, internal seals can fail, leading to slow drift or complete loss of function in the stick, and external leaks may become more pronounced. Continued operation risks unpredictable movement and potential damage to surrounding components.

Installation Tip

Before installation, carefully inspect the cylinder rod for any nicks or scratches that could damage new seals. Ensure the cylinder is fully retracted or extended as per the service manual to properly align mounting pins.

Service Note

Inspect the hydraulic hoses and fittings connected to the cylinder for leaks or wear, and check the condition of the mounting pins and bushings.
