14516932 — Boom Cylinder Seal Kit Voe14589155 Voe14516932 For Volvo Excavator Ec135B Ec140B Ecr88D

This boom cylinder seal kit is designed to reseal the hydraulic cylinder responsible for lifting and lowering the boom on Volvo excavators, preventing fluid leaks and maintaining consistent hydraulic pressure. It contains all necessary O-rings, wipers, and seals to restore the cylinder's sealing capability. Failure of these seals typically results in a slow-moving or drifting boom, external fluid leaks from the cylinder rod, and a loss of lifting power.

Failure Symptoms

The first indication of failing boom cylinder seals is often a slow drift of the boom when holding a position or a noticeable decrease in lifting speed. If unaddressed, the cylinder will continue to leak, leading to a significant loss of hydraulic pressure, making the boom sluggish or unable to lift heavy loads. This can compromise operational safety and productivity, potentially causing damage to the boom structure if it drifts unexpectedly.

Installation Tip

Carefully clean the cylinder bore and piston rod before installing the new seals to prevent any dirt or debris from causing damage. Ensure all seals are seated correctly and not twisted before reassembling the cylinder.

Service Note

Inspect the hydraulic fluid for contamination and check the condition of the hydraulic hoses connected to the boom cylinder during seal replacement.
