What Is a CAT Swing Motor?

A CAT swing motor is a hydraulic drive unit responsible for rotating the excavator’s upper structure (house). It works together with the swing gearbox and swing bearing to provide controlled, stable rotation during digging, loading, and positioning.

A failing swing motor can cause:

• Slow or jerky rotation

• Loss of swing power

• Overheating

• Oil leaks

• Abnormal noise or vibration

Replacing or repairing the swing motor restores safety, productivity, and machine control.
