11990347 — Steering Cylinder Seal Kit Voe11990347 For Volvo Loader L150 L150C L150D L150Clb

This is a steering cylinder seal kit, containing all necessary seals and O-rings to rebuild a worn steering cylinder and restore its proper function. It is manufactured from high-grade elastomers and metals designed to resist abrasion, heat, and hydraulic fluid degradation, unlike a failed seal that allows fluid bypass and loss of steering control. Operators may experience symptoms such as steering drift, stiffness, leaks around the cylinder rod, or a complete loss of steering assist when this seal kit is needed.

Failure Symptoms

The first indication of failing steering cylinder seals is often a noticeable leak of hydraulic fluid from around the cylinder rod. This can progress to sluggish steering response, difficulty holding a position, or a complete loss of steering control. Continued operation with leaking seals can lead to contamination of the hydraulic system and damage to the cylinder bore.

Installation Tip

Carefully clean the cylinder bore and rod before installing the new seals to prevent damage and ensure a proper seal. Ensure all seals are seated correctly and lubricated with system hydraulic fluid.

Service Note

When replacing steering cylinder seals, inspect the cylinder rod for scoring or damage and check the hydraulic fluid for contamination.
