This swing motor is the hydraulic actuator responsible for rotating the upper structure of the excavator relative to the undercarriage. It is built to Volvo's exacting standards, offering robust performance and longevity over a worn motor that may exhibit slow or jerky rotation. Operators will typically observe a loss of swing speed, inability to hold position, or audible grinding noises from the slew ring area when this component is failing.

Failure Symptoms

A failing swing motor will first manifest as a noticeable reduction in the speed of upper structure rotation or intermittent jerking during swings. If ignored, the rotation may become progressively slower and weaker, potentially leading to the inability to swing the boom or hold the load in position. The worst consequence is the risk of uncontrolled movement or inability to maneuver the machine effectively in a work environment.

Installation Tip

Thoroughly flush the hydraulic system and clean the hydraulic tank before installing the new swing motor to prevent contamination. Ensure the motor shaft splines are properly lubricated before attempting to engage them with the slew drive gear.

Service Note

Inspect the hydraulic pump, slew ring, and hydraulic control valves for proper operation and signs of wear when replacing the swing motor.
