What Is a Komatsu Swing Motor?

A Komatsu swing motor is a critical hydraulic component responsible for rotating the excavator’s upper structure (house). It works together with the swing gearbox and swing bearing to provide controlled, stable, and powerful rotation.

A failing swing motor can result in:

• Jerky or uneven rotation

• Loss of swing power

• Hydraulic oil leaks

• Excessive noise or overheating

• Increased downtime and safety risks

Replacing or repairing the swing motor promptly ensures maximum productivity and machine safety.
