14589136 — Boom Cylinder Seal Kit Voe14589136 For Volvo Excavator Ec290B Ec290C Fc3329C Ec700Bhr Ecr305C Ec300D Ec300E Ec290B

This is a boom cylinder seal kit, specifically designed to reseal the hydraulic boom cylinder on Volvo excavators, restoring its proper function. Manufactured to Volvo's exacting standards, it ensures a leak-free seal and optimal hydraulic performance, unlike worn seals that allow fluid bypass. Operators may notice the boom slowly drifting down when not actively lifting, or a loss of holding power in the boom position if the seals are failing.

Failure Symptoms

Visible hydraulic fluid leaks from the boom cylinder rod are the primary indicator of a failing seal kit. Without prompt replacement, the leakage will increase, leading to a gradual loss of boom control and potential inability to hold the boom in position. Continued operation risks internal cylinder damage and contamination of the hydraulic system.

Installation Tip

Carefully inspect the cylinder rod and bore for any nicks or scratches that could damage the new seals before installation. Ensure all seals are correctly oriented and fully seated to prevent immediate leakage.

Service Note

When replacing the boom cylinder seal kit, inspect the cylinder rod for scoring and check the hydraulic fluid for signs of contamination.
