OEM 800371903 The XCMG Disc (800371903) is a genuine OEM precision‑machined component engineered for critical thrust load management, axial positioning, and retaining functions within the driveline and wheel‑end assemblies of XCMG articulated dump trucks. This high‑strength disc, identified by part number 800371903, provides essential support for bearings, gears, and shafts, ensuring proper load distribution, reduced wear, and long‑term reliability in the most demanding mining, quarrying, and construction environments.
Manufactured from high‑strength alloy steel with precision grinding, heat treatment, and a durable corrosion‑resistant coating, the 800371903 disc delivers exceptional dimensional accuracy, fatigue resistance, and wear resistance under extreme shock loads and continuous heavy‑duty cycles. Its precision‑engineered dimensions and surface finish guarantee a perfect fit without modification.
The 800371903 disc features a ground flat and parallel surface for precise load transfer, a hardened wear surface, and a corrosion‑resistant finish, making it an indispensable component for maintaining driveline integrity, reducing downtime, and maximising uptime in your ADT fleet.
The 800371903 Disc is manufactured from high‑strength alloy steel with precision grinding and heat treatment, ensuring consistent dimensional accuracy and structural integrity across every unit.
Its precision‑ground flat and parallel surfaces provide an exact interface for thrust bearings, spacers, and retaining rings, ensuring proper load distribution and axial positioning.
The through‑hardened structure delivers excellent wear resistance and resistance to brinelling, maintaining its shape and load‑bearing capacity even under continuous heavy‑duty cycles.
The chamfered edges facilitate smooth assembly and reduce the risk of damage to seals and bearings during installation.
The zinc‑nickel plating provides robust corrosion protection, ensuring the disc remains serviceable even in wet, chemically aggressive environments.
In demanding applications such as open‑pit mines and aggregate quarries, the 800371903 delivers reliable, long‑lasting performance for your ADT’s driveline.
Articulated dump trucks rely on precision discs to manage axial thrust loads, maintain correct bearing preload, and ensure proper spacing of driveline components.
The 800371903 disc ensures that thrust loads are evenly distributed across the bearing faces, preventing excessive wear and premature failure of bearings and gears.
A worn or deformed disc can allow axial movement, leading to increased vibration, heat generation, and catastrophic failure of the driveline assembly.
Field data shows that ADTs equipped with genuine XCMG discs experience 40% fewer driveline load‑related failures compared to those using aftermarket or reused discs.
The disc’s precision ground surfaces ensure consistent load transfer and stress distribution, reducing fatigue on adjacent components.
Regular inspection of the disc is recommended; any signs of scoring, deformation, or corrosion should be addressed by immediate replacement.
The 800371903 is produced using advanced CNC turning, boring, and grinding processes, achieving tolerances of IT6 on all critical dimensions, ensuring a precise fit.
The alloy steel is forged and then through‑hardened to 38‑42 HRC, providing a uniform, wear‑resistant microstructure with excellent toughness and dimensional stability.
Both faces are precision‑ground to a surface roughness of ≤0.8 μm Ra, ensuring a smooth, low‑friction interface with mating components.
Flatness and parallelism are held to within 0.02 mm, ensuring even load distribution across the entire contact surface.
The chamfered edges are precisely machined to a 0.5 x 45° profile, facilitating easy installation and reducing the risk of seal or bearing damage.
Every unit undergoes 100% dimensional inspection, hardness testing, and surface finish verification to guarantee interchangeability with OEM specifications.
The 800371903 features a zinc‑nickel plating system that provides outstanding corrosion resistance, with over 500 hours of salt spray protection per ASTM B117.
The trivalent passivation layer seals the surface, preventing white rust formation and maintaining a uniform appearance even after prolonged exposure to moisture.
The alloy steel substrate is selected for its excellent hardenability and fatigue resistance, with a through‑hardened structure providing a tough, impact‑resistant core.
The combination of a hard, wear‑resistant surface and a tough core ensures the disc can withstand heavy loads and shock impacts without cracking or deforming.
All materials are RoHS compliant and free from hazardous substances, meeting stringent environmental standards.
The superior corrosion and wear resistance makes this disc ideal for the most demanding off‑highway applications.
The 800371903 is designed for professional installation using standard workshop tools, requiring careful handling to avoid damage to the precision‑ground surfaces.
To install, first clean the mating surfaces and the disc thoroughly, and inspect for any burrs or foreign material before assembly.
Position the disc carefully onto the shaft or into the housing, ensuring it seats fully against the shoulder or locating face.
Use an appropriate press tool or soft‑faced hammer to seat the disc if required, taking care to apply even pressure to avoid distortion.
During routine maintenance, inspect the disc for signs of wear, scoring, or corrosion, and replace if any damage is observed.
Always use genuine XCMG discs to ensure correct fit, material quality, and performance.
Investing in the 800371903 Disc delivers significant long‑term savings by preventing load‑related failures, reducing wear, and extending the service life of bearings and gears.
A failed disc can cause excessive bearing wear and misalignment, with repair costs exceeding $5,000.
Over a typical 15,000‑hour service life, an ADT’s driveline discs can experience millions of load cycles. The disc’s robust construction ensures it lasts the lifetime of the machine.
