Hyundai R250LC-7 R250LC-7A 31N7-40020BG Replacement excavator travel motor assy

The excavator travel motor is a hydraulic-driven component that converts hydraulic energy into mechanical rotation. High-pressure oil from the pump enters the motor, actuating pistons or gears to generate torque. A built-in reduction gear (often planetary) increases output force while reducing speed, driving the sprocket and tracks.

List of spare parts

Key features include:

• Bi-directional operation (forward/reverse via hydraulic flow control)

• Integrated brakes for slope stability

• Multi-speed control (some models)

Maintenance focuses on seal integrity, bearing wear, and hydraulic fluid cleanliness to prevent leaks and ensure efficiency. These motors provide high torque for rough terrain while enabling precise movement.
