VOE14589121 — Boom Cylinder Seal Kit Voe14589121 For Volvo Excavator Ec140C Ec140D Ec140E E120D

This is a hydraulic cylinder seal kit designed to maintain the integrity of the boom cylinder in Volvo excavators. It utilizes high-grade NBR rubber and robust metal components to prevent internal and external leakage, ensuring optimal hydraulic system performance and extending cylinder life beyond that of a worn or damaged seal. Operators may notice a gradual loss of boom control, slow or jerky movements, or visible hydraulic fluid leaks around the cylinder rod as the seals begin to fail.

Failure Symptoms

The first sign of a failing boom cylinder seal kit is often a slow drift of the boom when the hydraulic controls are not engaged. If left unaddressed, this leakage will worsen, leading to reduced lifting capacity and slower cylinder response times. Continued operation with compromised seals can lead to internal component damage and potential hydraulic system overheating.

Installation Tip

Ensure the cylinder bore and rod are thoroughly cleaned and free of any debris or burrs before attempting installation. Avoid using sharp tools that could nick or scratch the new seals during insertion.

Service Note

Inspect the hydraulic fluid for signs of contamination and check the cylinder rod for any scoring or damage that may require additional repair.
