VOE14512968 — Boom Cylinder Seal Kit Voe14589159 Voe14512968 For Volvo Excavator Ec330B Ec350D

This is a boom cylinder seal kit designed to replace worn or leaking seals within the hydraulic boom cylinder assembly. It is manufactured to meet stringent OEM quality standards, providing a reliable seal that prevents hydraulic fluid loss and contamination ingress, unlike a failed kit which allows fluid bypass and dirt intrusion. Operators may observe a slow-moving or drifting boom, external fluid leaks around the cylinder rod, or a spongy feel when operating the boom functions.

Failure Symptoms

The initial sign of a failing seal kit is often a visible leak of hydraulic fluid from the cylinder rod or a slow drift of the boom when it should be holding position. If ignored, internal seal failure will lead to a significant loss of lifting capacity and potentially internal cylinder damage. Continued operation risks uncontrolled boom movement and contamination of the hydraulic system.

Installation Tip

Carefully inspect the cylinder bore and rod for any scoring or imperfections that could damage the new seals before installation. Ensure all seal grooves are perfectly clean and free of debris.

Service Note

Check the hydraulic fluid level and condition, and inspect the main hydraulic pump for any signs of wear when replacing the boom cylinder seal kit.
