14589155 — Boom Cylinder Seal Kit Voe14589155 Voe14516932 For Volvo Excavator Ec135B Ec140B Ecr88D

This boom cylinder seal kit is designed to replace worn or leaking seals within the hydraulic boom cylinder of Volvo excavators, ensuring the containment of hydraulic fluid under pressure. It is crucial for maintaining the cylinder's lifting capacity and smooth operation, differing from a failed kit by preventing fluid bypass and external leaks. Operators may observe a slow-moving or drifting boom, external hydraulic fluid leaks around the cylinder, or a loss of lifting power when this seal kit is compromised.

Failure Symptoms

The first sign of a failing boom cylinder seal kit is often a visible hydraulic fluid leak around the cylinder rod or head. If not addressed, the cylinder may lose its ability to hold position, causing the boom to drift or sag under load, and eventually leading to a significant reduction in lifting capacity. This can create an unsafe operating environment and prevent the machine from performing essential tasks.

Installation Tip

Carefully inspect the cylinder bore and rod for any scoring or damage before installing the new seals, as imperfections can quickly damage new seals. Ensure all old seal material is completely removed from the grooves to prevent leaks.

Service Note

Inspect the hydraulic fluid and filter for signs of contamination and check the cylinder rod for any nicks or scratches that could damage the new seals.
