FPWM2408343 — Boom Cylinder Seal Kit Voe14589159 Voe14512968 For Volvo Excavator Ec330B Ec350D

This is a boom cylinder seal kit, essential for maintaining hydraulic pressure and preventing fluid loss within the boom lift cylinder of Volvo excavators. Manufactured to high standards, it ensures a tight seal comparable to original equipment, preventing the internal leakage that a worn or damaged seal would allow. Operators might observe the boom slowly drifting down when holding position, a lack of full lifting power, or external hydraulic fluid leaks around the cylinder rod when these seals fail.

Failure Symptoms

The most common symptom of failing boom cylinder seals is the boom slowly lowering or drifting when the hydraulic controls are not engaged. This can progress to a noticeable loss of lifting power and increased external fluid leakage from the cylinder rod. If left unaddressed, the cylinder may lose its ability to hold position reliably, impacting work efficiency and potentially causing damage to the boom or bucket.

Installation Tip

Carefully inspect the cylinder rod for any nicks or scratches that could damage the new seals before installation. Ensure all seals are lubricated with appropriate hydraulic fluid before insertion to prevent tearing.

Service Note

When rebuilding a hydraulic cylinder, it is advisable to inspect the cylinder bore for wear or damage and clean the hydraulic fluid for contaminants.
