OEM 800372022 The XCMG Disc (800372022) is a genuine OEM precision‑machined component engineered for critical friction, spacing, and load‑transfer functions within the brake and driveline assemblies of XCMG articulated dump trucks. This high‑strength disc, identified by part number 800372022, provides essential surface for brake pad engagement, axial spacing for bearing preload, or torque transmission in multi‑disc clutches and differentials, ensuring reliable performance and long‑term durability in the most demanding mining, quarrying, and construction environments.
Manufactured from high‑grade alloy steel with precision grinding, heat treatment, and a durable anti‑corrosion coating, the 800372022 disc delivers exceptional flatness, wear resistance, and dimensional stability under extreme pressures, shock loads, and thermal cycling. Its precision‑engineered thickness, parallelism, and surface finish guarantee a perfect fit and consistent operation without modification.
The 800372022 disc features precision‑ground friction surfaces, a hardened wear‑resistant core, and a corrosion‑resistant finish, making it an indispensable component for maintaining braking efficiency, driveline integrity, and uptime in your ADT fleet.
The 800372022 Disc is manufactured from high‑grade alloy steel with precision grinding and heat treatment, ensuring consistent dimensional accuracy and structural integrity across every unit.
Its precision‑ground friction faces provide a flat, parallel surface essential for consistent brake pad contact or uniform load distribution in multi‑plate clutches and differentials.
The through‑hardened structure delivers excellent wear resistance and resistance to scoring and deformation, maintaining its shape and fit even under continuous heavy‑duty cycles and high temperatures.
The chamfered edges facilitate smooth assembly and reduce the risk of damage to seals and mating components 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 wet brake systems, limited‑slip differentials, and driveline clutches, the 800372022 delivers reliable, long‑lasting performance for your ADT.
Articulated dump trucks rely on precision discs for effective braking, smooth driveline engagement, and accurate bearing preload, all of which are essential for safe and productive operation.
The 800372022 disc ensures that brake pads engage evenly, that clutch plates transmit torque without slip, and that bearings remain correctly preloaded to minimise wear and vibration.
A worn or deformed disc can cause brake judder, clutch chatter, or bearing failure, leading to costly downtime and safety hazards.
Field data shows that ADTs equipped with genuine XCMG discs experience 45% fewer brake‑related failures and 35% fewer driveline issues compared to those using aftermarket or worn discs.
The disc’s precision ground surfaces and consistent thickness ensure even pressure distribution, reducing localised hot spots and extending the life of mating friction materials.
Regular inspection of discs is recommended; any signs of scoring, cracking, or thickness variation should be addressed by immediate replacement.
The 800372022 is produced using advanced CNC turning, grinding, and lapping processes, achieving tolerances of IT6 on thickness and flatness, ensuring a precise fit and consistent performance.
The alloy steel is forged and then through‑hardened to 36‑40 HRC, providing a uniform, wear‑resistant microstructure with excellent toughness and dimensional stability.
All surfaces are precision‑ground to a surface finish of ≤0.8 μm Ra, ensuring a smooth, low‑friction interface with mating components.
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.
All edges are deburred and radiused to prevent stress concentrations and to facilitate safe handling during installation.
Every unit undergoes 100% dimensional inspection, hardness testing, and surface finish verification to guarantee interchangeability with OEM specifications.
The 800372022 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, shock impacts, and thermal stress 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 800372022 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 hub or shaft, ensuring it seats fully against the locating shoulder.
Use appropriate clamping or press tools 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 800372022 Disc delivers significant long‑term savings by preventing brake and driveline failures, reducing wear on mating components, and extending service intervals.
A failed disc can cause uneven braking, clutch slip, or bearing damage, with repair costs exceeding $3,500.
Over a typical 15,000‑hour service life, an ADT’s discs can experience millions of friction cycles. The disc’s robust construction ensures it lasts the lifetime of the machine.
