The accurately machined splines or drive lugs ensure positive torque transmission without backlash, reducing shock loads on mating components and extending service life.
The disc’s balanced design and precise geometry minimise vibration and rotational runout, improving system smoothness and reducing noise.
In demanding applications such as open‑pit mines, aggregate quarries, and heavy construction sites, the 800374227 delivers reliable, long‑lasting friction performance for your ADT’s brake and clutch systems.
The 800374227 disc is produced using advanced forging, heat treatment, and precision grinding processes, achieving tight tolerances on all critical dimensions, including thickness, flatness, and surface finish.
The alloy steel is carefully selected for its excellent hardenability, wear resistance, and thermal conductivity, ensuring reliable performance under cyclic thermal and mechanical loading.
After forging, the disc undergoes a controlled induction‑hardening process that creates a hard, wear‑resistant surface layer (45–55 HRC) while maintaining a tough, ductile core that absorbs shock loads.
The friction faces are precision‑ground to a surface finish of Ra ≤ 0.8 µm and a flatness tolerance of ≤ 0.05 mm, providing an optimal contact surface for brake pads or clutch plates.
After machining, each disc undergoes 100% dimensional inspection, hardness testing, and magnetic particle inspection to verify its integrity and performance.
Sample units from each production batch are subjected to thermal cycling, wear testing, and friction coefficient validation to ensure long‑term durability and performance.
Articulated dump trucks rely on high‑quality friction discs to ensure safe braking and smooth power transmission, making the quality and precision of each disc vital to overall machine safety, performance, and reliability.
The 800374227 disc serves as a critical friction element in wet or dry brake systems and in multi‑disc clutch packs, providing the necessary friction surface to engage or disengage power flow.
A substandard or worn disc can lead to brake fade, clutch slippage, erratic engagement, and catastrophic drivetrain failure — risks that are eliminated by using genuine XCMG discs.
Field data from mining operations shows that ADTs equipped with genuine XCMG discs experience 40% fewer brake and clutch‑related failures and a 25% reduction in drivetrain downtime, directly improving machine availability and safety.
The disc’s precision‑ground surfaces and optimal hardness minimise wear on mating components, reducing the frequency of replacements and lowering operating costs.
Regular inspection of discs for signs of wear, scoring, cracking, or thermal discoloration is recommended; any compromised discs should be replaced promptly with genuine 800374227 components.
The 800374227 disc is manufactured from high‑grade alloy steel that provides an exceptional combination of thermal stability, wear resistance, and mechanical strength, ensuring reliable performance under the most severe operating conditions.

Before installation, carefully inspect the disc for any signs of damage, wear, or corrosion that may have occurred during storage or transport, and ensure that the mating components are clean and free from debris.
Apply a thin film of clean oil or assembly lubricant to the splines or drive lugs to facilitate assembly and prevent galling during initial operation.
Carefully align the disc with the hub or shaft, ensuring that it is fully seated and that all retaining rings and fasteners are properly installed to prevent axial movement.
During routine maintenance, inspect the disc for signs of wear, scoring, cracking, or thermal distortion, and replace it if any damage is detected.
Always handle the disc with clean, lint‑free gloves to prevent contamination of the precision‑ground friction surfaces.
