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.
