HZBXLB00070 — For Volvo Excavator Ec350D Swing Motor Seal Kit

This swing motor seal kit is essential for maintaining the integrity of the swing motor assembly in Volvo excavators, preventing hydraulic fluid leaks and contamination. Constructed from high-performance seals and O-rings, it ensures the motor operates smoothly and efficiently, unlike a worn kit that allows fluid loss and ingress of dirt. Operators may notice slow or jerky swing movements, or visible hydraulic fluid leaks around the swing motor housing if the seals fail.

Failure Symptoms

The initial symptom of a failing swing motor seal kit is often a gradual loss of swing speed or power, accompanied by visible hydraulic fluid leaks around the swing motor. If ignored, the leaks will worsen, leading to insufficient hydraulic pressure for smooth rotation and potential internal damage to the swing motor. The ultimate consequence is the inability to effectively slew the upper structure of the excavator.

Installation Tip

Thoroughly clean all internal and external surfaces of the swing motor housing before installing new seals to prevent contamination. Ensure all seals are properly seated and lubricated with hydraulic fluid to prevent tearing during assembly.

Service Note

When replacing the swing motor seal kit, inspect the swing motor gears and bearings for wear and contamination.
