The 859829241 reaction plate 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 (SAE 4140 / 42CrMo4) is carefully selected for its high strength, toughness, and hardenability, with the induction‑hardening process creating a wear‑resistant surface layer (55–60 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, providing an optimal surface for clutch disc contact and ensuring consistent friction characteristics.
The drive lugs and locating features are precision‑machined to exacting tolerances, ensuring proper fitment and alignment within the clutch housing.
After machining and heat treatment, each plate undergoes 100% dimensional inspection, hardness testing, and flatness verification to ensure it meets the required specifications.
Sample units from each production batch are subjected to fatigue testing, wear testing, and thermal cycling to validate long‑term durability and performance.
Articulated dump trucks rely on the C4 clutch reaction plate to provide a stable backing surface for the C4 clutch pack, ensuring consistent torque transfer and smooth gear engagement.
The 859829241 reaction plate serves as a critical component in the C4 clutch assembly, reacting the clamping force of the hydraulic piston and distributing it evenly across the friction discs.
