LIUGONG 04Y0072 Motor Grader Circle Turn Worm Gearbox Assembly

● LIUGONG 04Y0072 Worm Gearbox Technical Support

● Part number 04Y0072 (bidirectionally interchangeable with former part number 04E0057) is the genuine heavy-duty worm reduction gearbox assembly engineered for LIUGONG motor grader blade circle rotation systems.

● Material number 04Y0072 is mounted on the motor grader drawbar frame assembly, directly coupling the hydraulic circle drive motor to the circle turn pinion. Driven by hydraulic fluid power, the high-ratio internal worm and bronze worm wheel convert hydraulic motor rotation into massive reduction torque, enabling smooth, non-slip 360-degree rotation and precise angle holding of the heavy grading moldboard.

● Maintain correct heavy-duty industrial gear oil levels in the worm housing and periodically inspect output shaft splines, backlash tolerance, and housing seal integrity to prevent leakage and gear wear under severe rock grading loads.
