FPWM2408342 — Boom Cylinder Seal Kit Voe14589139 For Volvo Excavator Ec330C Ec340D Ec350E Ec360B Ec380D Ec380E

This is a boom cylinder seal kit for Volvo excavators, containing all necessary seals to restore the integrity of the boom cylinder. It prevents hydraulic fluid leakage and ensures the cylinder operates efficiently, providing smooth and powerful boom movements. A failing seal kit will typically result in visible hydraulic leaks from the boom cylinder, slow or weak boom lifting capabilities, and potential 'drift' of the boom when not actively being controlled.

Failure Symptoms

The most immediate sign of a failing boom cylinder seal kit is visible hydraulic fluid leakage from the cylinder rod or at the cylinder end caps. This can progress to a noticeable loss of lifting force, slow boom extension/retraction, and the boom may drift downwards under load when not actively being controlled.

Installation Tip

Before installing new seals, carefully inspect the cylinder rod for any scratches or imperfections that could damage the seals; polish or replace the rod if necessary. Ensure all seals are properly lubricated with clean hydraulic fluid prior to insertion.

Service Note

Inspect the boom cylinder rod for scoring and the cylinder's internal components for wear during seal replacement.
