HZBXLB00059 — For Volvo Excavator Ec140B Swing Motor Seal Kit

This is a Swing Motor Seal Kit designed to prevent hydraulic fluid leakage from the swing motor assembly on Volvo excavators, ensuring optimal performance of the slewing function. It is constructed from high-grade sealing materials that resist wear and hydraulic fluid degradation, offering superior longevity compared to a worn or damaged seal that would allow fluid bypass. Operators may observe slow or jerky swing movements, a noticeable loss of hydraulic power during slewing, or hydraulic fluid leaks around the swing motor housing when these seals fail.

Failure Symptoms

A gradual decrease in swing speed and torque is a common initial symptom of failing swing motor seals. If left unaddressed, the swing function may become sluggish, lose holding power, and exhibit significant external hydraulic fluid leaks. This can lead to reduced operational efficiency and potential environmental contamination.

Installation Tip

Thoroughly clean the swing motor housing and all internal components to remove any debris or old seal material before installing the new seals. Ensure new seals are properly lubricated with clean hydraulic oil to prevent tearing during installation.

Service Note

When replacing swing motor seals, inspect the swing motor's internal gears and bearings for wear or damage, and check the hydraulic fluid for contamination.
