Failure Symptoms

The first indication of a failing swing motor assembly is often a noticeable reduction in the speed or smoothness of the upper structure's rotation. If ignored, the swing function may become intermittent, with the machine struggling to maintain position under load. Continued operation risks uncontrolled rotation or the inability to swing, significantly impacting operational efficiency and safety.

Installation Tip

Ensure the hydraulic system is properly bled after installation to remove any air that could cause cavitation and damage the new motor. Do not reuse old hydraulic lines or fittings, as they may be contaminated or weakened.

Service Note

Flush the hydraulic system and replace the hydraulic fluid and filter when installing a new swing motor assembly to prevent contamination.
