11990244 — Boom Lift Cylinder Seal Kit 11990244 For Volvo Loader L50

This is a boom lift cylinder seal kit specifically designed for Volvo L50 loaders, restoring the hydraulic cylinder's ability to hold pressure and extend/retract smoothly. It is manufactured to precise specifications, offering superior sealing performance over worn seals that cause gradual loss of boom height and external leaks. Operators may observe the boom slowly drifting down when not actively being lifted, external hydraulic fluid leaks around the cylinder, or a spongy feel during operation.

Failure Symptoms

The first sign of failure is often a slow, uncontrolled descent of the boom when the control lever is released. If ignored, the leakage will increase, leading to a significant loss of lifting capacity and potentially causing the boom to drift down rapidly. This can create an unsafe operating condition and put stress on the hydraulic system.

Installation Tip

Carefully inspect the cylinder rod for any imperfections or scoring before installing the new seals, as these can damage the seals and cause immediate leakage. Ensure all old seal material is completely removed from the cylinder grooves.

Service Note

Inspect the boom lift cylinder rod for scoring or wear, and check the hydraulic fluid for signs of contamination or degradation.
