XCMG Loader Spare Part 231200114 (XDH080J.02‑2) Pinion Gear​ is a high-strength, genuine drive gear developed specifically for the XCMG XDH080J and other designated drive axle or reduction gearbox systems.

XCMG Loader Spare Part 231200114 (XDH080J.02‑2) Pinion Gear​ is a high-strength, genuine drive gear developed specifically for the XCMG XDH080J and other designated drive axle or reduction gearbox systems. It is typically manufactured from premium alloy carburizing steel (20CrMnTi or higher grade) forged blanks, precisely shaped via CNC gear hobbing, and then heat-treated through carburizing, quenching, and tempering processes. This achieves a tooth surface hardness of HRC58‑62 while maintaining a tough and ductile core. The tooth profile is finished using high-precision grinding or shaving for optimal tip relief, effectively reducing meshing noise and impact stress. Strict manufacturing controls are applied to limit cumulative pitch error and tooth alignment deviation, ensuring resistance to tooth breakage or chipping during heavy-load starts, braking, and directional reversals.

It is primarily installed at the input or intermediate shaft position of the drive axle main reducer or wheel reducer, where it smoothly transfers power from a high-speed shaft to a higher torque output stage. Application scenarios center on XCMG large loaders, mining dump trucks, and certain special engineering machines equipped with XDH-series transmission systems. It is particularly suited to harsh, low-speed/high-torque, fully-loaded operating environments such as open-pit coal mines, metal mines, hard rock stripping operations, and heavy-duty bulk material handling at ports. This gear is an essential genuine replacement component during major drivetrain overhauls or when replacing gear pairs, restoring the machine’s climbing ability, traction, and operational stability.single piece or full container bulk export available with one-stop customs, inspection & certificate of origin service.
