FPCY2508236 — Boom Cylinder Seal Kit For Volvo Excavator Ec25

This boom cylinder seal kit is designed to replace the worn seals within the hydraulic cylinder responsible for the excavator's boom movement. It contains all necessary seals to restore the cylinder's integrity, preventing internal and external leaks and maintaining optimal hydraulic pressure. A failed seal kit will manifest as external fluid leaks from the cylinder rod, sluggish boom operation, or the boom drifting down when not actively being controlled.

Failure Symptoms

The initial indication of worn boom cylinder seals is often a visible hydraulic fluid leak from around the cylinder rod. If left unaddressed, this leakage will worsen, leading to a loss of hydraulic pressure and noticeably slower or weaker boom movements. Eventually, the boom may drift downwards under its own weight when the hydraulic control is not engaged, compromising operational safety.

Installation Tip

Thoroughly clean the cylinder bore and rod before installing new seals to prevent damage from debris. Ensure all seals are seated correctly and not twisted, as this will cause immediate leakage.

Service Note

Inspect the cylinder rod for scoring or damage, and check the hydraulic fluid for contamination.
