Axle gear unit 4.Z3.2.00B80020000 (clockwise)

Product Introduction

This 4.Z3.2.00B80020000 clockwise axle gear unit is a complete main drive assembly for wheel loader drive axle, also known as the axle main reducer assembly. It adopts clockwise spiral bevel gear pair design, which converts horizontal power from the transmission into vertical driving torque and transfers power to the wheel side planetary reduction mechanism. It is the core power distribution component of the loader drive axle, bearing heavy torque load during earthmoving, loading and mining operations.

The assembly housing is made of high-strength cast iron, with thickened wall structure to resist impact and vibration on construction sites. The spiral bevel gear pair is forged from premium alloy steel and processed through precision gear cutting and carburizing heat treatment. The gear tooth surface reaches high hardness, ensuring smooth meshing, low running noise and excellent overload resistance. The whole unit is pre-assembled, adjusted and tested before leaving the factory, including bearing preload and gear meshing clearance calibration. It can be directly installed on the drive axle without complex repeated debugging, greatly shortening equipment overhaul time.

We strictly follow OEM dimensional and assembly standards for production, fully interchangeable with original spare parts. We supply OEM equivalent and premium aftermarket quality grades. Every finished axle gear unit undergoes no-load running test and leakage inspection before shipment. Export-grade packaging and complete customs documents are available for overseas construction machinery repair shops and equipment distributors.
