OEM 800371907 The XCMG Ring Gear (800371907) is a genuine OEM precision‑manufactured internal gear engineered for high‑torque, low‑speed power transmission within the wheel‑end planetary hub assemblies of XCMG articulated dump trucks. This precision‑hardened ring gear, identified by part number 800371907, serves as the stationary outer gear element in the planetary gear train, providing the reactive torque path that enables smooth, efficient torque multiplication and speed reduction under the most severe mining, quarrying, and heavy construction conditions.
Manufactured from high‑quality alloy steel with precision gear shaping, case‑hardening, and profile grinding, the 800371907 ring gear delivers exceptional wear resistance, high load‑carrying capacity, and long‑term reliability under extreme shock loads and continuous heavy‑duty cycles. Its precision‑engineered internal tooth geometry guarantees a perfect mesh with planetary gears without modification.
The 800371907 ring gear features a precision‑ground internal tooth profile for smooth, quiet operation, a case‑hardened surface for outstanding durability, and a corrosion‑resistant finish, making it an indispensable component for maintaining driveline power, reducing wheel‑end stress, and maximising uptime in your ADT fleet.
The 800371907 Ring Gear is manufactured from high‑quality alloy steel with precision gear shaping, case‑hardening, and profile grinding, ensuring consistent tooth geometry and structural integrity across every unit.
Its precision‑ground internal involute tooth profile provides smooth, quiet operation and efficient torque transfer, minimising power loss and reducing stress on the planetary gear train.
The case‑hardened surface (58‑62 HRC) offers exceptional wear resistance and resistance to pitting and spalling, maintaining tooth integrity under continuous high‑load operation.
The gear’s precise internal tooth geometry ensures proper mesh with planetary gears, distributing loads evenly across the tooth flank and extending service life.
Its corrosion‑resistant coating provides robust protection against moisture, salts, and chemicals, ensuring reliable operation in harsh environments.
In demanding applications such as open‑pit mines and aggregate quarries, the 800371907 delivers reliable, long‑lasting power transmission for your ADT’s driveline.
Articulated dump trucks rely on planetary gear sets at each wheel end to multiply driveline torque, enabling the machine to move heavy loads and climb steep haul roads.
The 800371907 ring gear works in conjunction with the sun and planet gears to achieve the required reduction ratio, delivering high torque at low speed for maximum tractive effort.
A worn or damaged ring gear can cause increased noise, vibration, and reduced torque capacity, leading to costly downtime and potential driveline failure.
Field data shows that ADTs equipped with genuine XCMG ring gears experience 50% fewer wheel‑end failures compared to those using rebuilt or aftermarket gears.
The gear’s precision‑ground tooth profile and hardened surface ensure consistent performance throughout its service life.
Regular inspection of ring gears is recommended; any signs of pitting, wear, or tooth damage should be addressed immediately.
The 800371907 is produced using advanced gear hobbing and grinding processes, achieving AGMA quality grade 10 or higher on all gear tooth profiles.
The alloy steel substrate is case‑hardened using a controlled carburising process, providing a uniform case depth and hardness profile for optimal wear resistance.
The internal teeth are profile‑ground to achieve a surface finish of ≤0.4 μm Ra, ensuring smooth, quiet operation and minimising friction losses.
The root fillet is precisely radiused to reduce stress concentrations, improving the gear’s fatigue strength and resistance to tooth breakage.
All edges are deburred and chamfered to prevent stress concentrations and to facilitate safe handling during installation.
Every unit undergoes 100% dimensional inspection, hardness testing, and magnetic particle inspection to guarantee interchangeability with OEM specifications.
The 800371907 features a case‑hardened surface (58‑62 HRC) that provides outstanding wear resistance and resistance to pitting and spalling.
The tough, ductile core (30‑35 HRC) provides excellent shock resistance, preventing tooth breakage under impact loads.
The gear is coated with a zinc‑nickel plating or phosphate and oil finish, providing excellent corrosion protection, with over 500 hours of salt spray resistance.
The combination of a hard, wear‑resistant surface and a tough core ensures the gear can withstand heavy loads and shock impacts without premature failure.
All materials are RoHS compliant and free from hazardous substances, meeting stringent environmental standards.
The superior wear and corrosion resistance makes this gear ideal for the most demanding off‑highway applications.
The 800371907 is designed for professional installation using standard workshop tools, requiring careful handling to avoid damage to the precision‑ground tooth surfaces.
To install, first clean the gear and mating components thoroughly, and inspect for any burrs or foreign material before assembly.
Carefully align the ring gear with the planetary carrier and housing, ensuring proper mesh with the planet gears before securing the assembly.
Apply a thin layer of clean gear oil to the tooth surfaces before assembly to ensure proper lubrication during initial operation.
During routine maintenance, inspect the gear for signs of pitting, wear, or tooth damage, and replace if any defects are observed.
Always use genuine XCMG ring gears to ensure correct fit, material quality, and performance.
