The 860171386 flange is produced using advanced forging, heat treatment, and precision machining processes, achieving tight tolerances on all critical dimensions, including flange diameter, bolt hole positions, and face flatness.
The alloy steel (SAE 4140 / 42CrMo4) is carefully selected for its high tensile strength, toughness, and fatigue resistance, with the quench and tempering process achieving a uniform hardness of 28–32 HRC while maintaining excellent ductility.
The mating face is induction‑hardened to ≥ 55 HRC to resist wear and deformation, while the bolt hole positions are precision‑drilled and reamed to ensure accurate alignment with mating flanges.
The face is precision‑ground or fine‑turned to a surface finish of Ra ≤ 0.8 µm, providing an optimal sealing surface that minimises gasket creep and prevents leakage.
After machining, each flange 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 torque testing, fatigue testing, and dimensional verification to validate long‑term durability and performance.
Articulated dump trucks rely on flanges to connect shafts, housings, hydraulic lines, and structural members, making the quality and precision of each flange vital to overall drivetrain performance, efficiency, and reliability.
The 860171386 flange serves as a critical connection point in these assemblies, ensuring that torque is transferred efficiently and that loads are distributed evenly across the joint.
A substandard or worn flange can lead to joint loosening, misalignment, fluid leakage, and premature failure of connected components — risks that are eliminated by using genuine XCMG flanges.
Field data from mining operations shows that ADTs equipped with genuine XCMG flanges experience significantly fewer connection‑related failures and a marked reduction in drivetrain downtime, directly improving machine availability and productivity.
The flange’s precision‑machined surfaces and accurate bolt hole positioning minimise stress concentrations and ensure even clamp load, extending the life of bolts and mating components.
Regular inspection of flanges for signs of wear, corrosion, or bolt hole elongation is recommended; any compromised flanges should be replaced promptly with genuine 860171386 components.
The 860171386 flange is manufactured from high‑grade forged alloy steel that provides an exceptional combination of strength, toughness, and fatigue resistance, ensuring reliable performance under the most severe operating conditions.
