ZBXLB00073 — For Volvo Ec350D Arm Cylinder Seal Kit

This is an arm cylinder seal kit designed to maintain the integrity of the hydraulic cylinder on Volvo excavators. It is manufactured with high-quality sealing materials to prevent leaks and ensure smooth, efficient cylinder operation, unlike a worn kit that allows fluid bypass. Operators may notice hydraulic drift, leaks around the cylinder rod, or a loss of lifting force when this seal kit fails.

Failure Symptoms

The first sign of a failing arm cylinder seal kit is often visible hydraulic fluid leakage from the cylinder rod or slower, less responsive arm movements. If ignored, the leakage will worsen, leading to a significant loss of hydraulic pressure and potentially causing the arm to drift or fail to hold its position under load.

Installation Tip

Carefully clean the cylinder bore and rod before installing the new seals to prevent contamination. Ensure all sealing surfaces are free of burrs or damage.

Service Note

Inspect the cylinder rod for scoring or damage, and check the hydraulic fluid level and condition when replacing the arm cylinder seal kit.
