Failure Symptoms

The primary symptom of a failing arm cylinder seal kit is external hydraulic fluid leakage from the cylinder rod. This will progress to a loss of hydraulic pressure, resulting in slower arm movements and reduced lifting capacity. If ignored, the cylinder may not be able to hold its position, posing a risk to operational stability.

Installation Tip

Ensure the cylinder rod is clean and free of any burrs or damage before installing the new seals to prevent immediate failure. Do not force the seals into the grooves; they should seat smoothly.

Service Note

Inspect the arm cylinder rod for scoring or pitting, as any surface imperfections can lead to premature seal failure.
