If you run Shacman heavy trucks or mining vehicles with Hande HDZ300 axles, you may know this: a persistent whine from the rear axle that worsens under acceleration, or metal particles in the differential oil.
These symptoms usually point to a worn bevel gear pair — the component that transfers torque from the driveshaft to the differential and changes rotation direction by 90 degrees. When gear teeth wear, pit, or break, the axle loses smooth torque transmission. The result is noise, vibration, power loss, and eventually complete axle failure.
We are Shaanxi Tolizer Machinery Equipment Co., Ltd., a China-based supplier of heavy-duty powertrain and drivetrain components, including Engine Electrical Parts, Turbo Kits and Pipes, and Hydraulic System parts. We serve global distributors, fleets, and aftermarket workshops.
Our HD90149320031 Bevel Gear Pair is a direct replacement for the original Hande component. It fits the HDZ300 middle and rear drive axle with a gear ratio of 28/21 (i=1.333) and weighs approximately 23.5 kg. Commonly used in Shacman X3000, F3000, and M3000 trucks. Each gear is forged from 20CrMnTi alloy steel and precision-ground for smooth meshing and long service life.
Choosing this gear pair means choosing a ready-to-fit set that restores torque transmission and eliminates differential whine — so your trucks stay on the road.

Note: If you are unsure about compatibility, share your axle model, VIN, or a photo of the old gear set. We will confirm fitment before your order.
Compatible with Hande HDZ300 axles in Shacman, Foton, and other Chinese heavy truck platforms. We also supply Crankshaft Kits, Valve Train Parts, and Engine Gasket Kits for Shacman, SINOTRUK, LiuGong, FAW, and other major brands.
