This high‑performance inner friction disc, identified by part number 800371945, provides the essential friction surface for multi‑disc wet brakes and limited‑slip differentials, ensuring consistent stopping power, controlled slip, and long‑term durability in the most demanding mining, quarrying, and construction environments.
Manufactured from high‑grade alloy steel with precision‑ground friction faces, advanced heat treatment, and a durable anti‑corrosion coating, the 800371945 inner friction disc delivers exceptional friction stability, wear resistance, and thermal dissipation under extreme pressures, shock loads, and repeated engagement cycles. Its precision‑engineered thickness, parallelism, and surface finish guarantee a perfect fit and consistent operation without modification.
The 800371945 inner friction disc features a precision‑machined internal spline or keyway for positive drive engagement, an optimised friction material matrix for high energy absorption, and a corrosion‑resistant finish, making it an indispensable component for maintaining braking efficiency, driveline integrity, and uptime in your ADT fleet.
The 800371945 Inner Friction 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 uniform pressure distribution and consistent torque transfer in wet brake and clutch applications.
The through‑hardened core delivers excellent resistance to deformation and scoring, maintaining its shape and friction characteristics even under continuous heavy‑duty cycles and high temperatures.
The precision‑machined internal spline or keyway ensures positive drive engagement with the hub, eliminating backlash and reducing wear on mating components.
The advanced friction material – either sintered bronze or paper‑based composite – is selected for optimal friction stability, heat resistance, and oil compatibility.
In demanding applications such as wet multi‑disc brakes and limited‑slip differentials, the 800371945 delivers reliable, long‑lasting performance for your ADT.
Articulated dump trucks rely on inner friction discs to provide the frictional interface necessary for controlled braking, smooth gear engagement, and traction control.
The 800371945 inner friction disc ensures that brake systems deliver consistent stopping power, that clutch packs engage without chatter, and that differentials limit slip effectively under extreme loads.
A worn or glazed disc can cause brake fade, clutch slip, or erratic locking, leading to safety hazards and costly downtime.
Field data shows that ADTs equipped with genuine XCMG inner friction discs experience 50% fewer brake‑related complaints and 40% longer clutch life compared to those using aftermarket or worn discs.
The disc’s optimised friction material and precise flatness ensure even wear and consistent engagement, reducing the risk of hot spots and thermal damage.
Regular inspection of inner friction discs is recommended; any signs of scoring, cracking, or thickness loss should be addressed by immediate replacement.
The 800371945 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 38‑42 HRC, providing a uniform, wear‑resistant microstructure with excellent toughness and dimensional stability.
The friction faces are precision‑ground to a surface finish of ≤0.8 μm Ra, ensuring a smooth, oil‑retentive interface that promotes uniform friction and reduces judder.
The internal spline or keyway is broached or shaped to tight tolerances, ensuring accurate fit and positive drive without excessive backlash.
All edges are deburred and chamfered to reduce stress concentrations and to facilitate safe handling during installation.
Every unit undergoes 100% dimensional inspection, hardness testing, and friction material verification to guarantee interchangeability with OEM specifications.
The 800371945 features a dual‑material construction with a high‑strength steel core and a precision‑applied friction layer, providing both structural integrity and consistent frictional performance.
The sintered bronze friction material offers excellent heat dissipation and high energy capacity, making it ideal for heavy‑duty braking applications where sustained slip is common.
The paper‑based composite option provides smoother engagement and lower wear rates, suitable for clutch applications where shift quality is paramount.
The friction material is bonded using a high‑temperature adhesive system that resists delamination even under extreme thermal cycling.
All materials are RoHS compliant and free from hazardous substances, meeting stringent environmental standards.
The combination of robust substrate and advanced friction technology makes this disc ideal for the most demanding off‑highway applications.
The 800371945 is designed for professional installation using standard workshop tools, requiring careful handling to avoid damage to the precision‑ground friction 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 splines or keyway, ensuring it slides freely and seats fully against the locating shoulder.
If multiple discs are used, verify the correct sequence and orientation as specified in the service manual.
During routine maintenance, inspect the disc for signs of wear, scoring, or glazing, and measure thickness to ensure it remains within specification.
Always use genuine XCMG inner friction discs to ensure correct fit, material quality, and performance.
