ZBXLB00075 — Arm Cylinder Seal Kit For Volvo Excavator Ec360B

This seal kit is designed to replace the worn seals within the arm cylinder of Volvo excavators, ensuring the containment of hydraulic pressure for effective boom and bucket operation. Manufactured to meet stringent Volvo standards, it provides a reliable seal that prevents internal leakage and external fluid seepage, unlike degraded original seals. Operators may notice slow or weak arm movement, external hydraulic fluid leaks around the arm cylinder, or the arm drifting down when not actively holding a position if this kit fails.

Failure Symptoms

The first sign of a failing arm cylinder seal kit is often a gradual loss of lifting force or a slight drift of the arm when holding a position. If left unaddressed, the leakage will increase, leading to slower arm response, potential overheating of the hydraulic fluid, and visible external leaks. Continued operation risks reduced digging efficiency and potential damage to the cylinder rod or bore.

Installation Tip

Ensure the cylinder rod is perfectly clean and free of any burrs or scratches before installing the new seals. Carefully guide the seals onto the piston or rod, avoiding any twisting or stretching that could compromise their integrity.

Service Note

Inspect the arm cylinder rod for scoring or wear, and clean the cylinder bore thoroughly before installing the new seals.
