OEM 860682035 The XCMG Planetary Gear Train (860682035) is a genuine OEM integrated planetary assembly engineered to provide high‑ratio torque multiplication and smooth power distribution in the transmissions and final drives of XCMG articulated dump trucks. This precision‑built gear train, identified by part number 860682035, combines a sun gear, multiple planet gears, and a ring gear into a compact, highly efficient unit that delivers exceptional torque density and durability in the most demanding mining and construction applications.
Manufactured from premium case‑hardening alloy steels with precision‑ground gear teeth and advanced heat treatment, the 860682035 planetary gear train offers outstanding wear resistance, high load‑carrying capacity, and extended fatigue life. Its advanced design ensures even load sharing among planet gears, reducing stress on individual teeth and minimising noise and vibration.
The 860682035 planetary gear train is fully compatible with XCMG ADT series, providing a direct replacement solution that restores original driveline efficiency, reduces parasitic losses, and ensures reliable power transmission – keeping your fleet productive and cost‑effective.
The 860682035 Planetary Gear Train is a precision‑manufactured assembly that combines sun, planet, and ring gears to achieve high gear ratios in a compact footprint, making it ideal for the space‑constrained drivelines of XCMG articulated dump trucks.
Planetary gear trains are fundamental to heavy‑duty transmissions because they distribute torque across multiple planet gears, significantly reducing the load on each tooth and enabling much higher torque capacity than conventional parallel‑shaft gears.
This genuine XCMG assembly is manufactured to exacting tolerances, with all gears precision‑ground and shot‑peened to ensure optimum tooth contact patterns, minimal backlash, and quiet operation.
The carburised and hardened tooth surfaces provide exceptional resistance to pitting and spalling, while the tough cores absorb the high shock loads that occur during gear changes and rough terrain operation.
Its balanced design ensures even load sharing among the planet gears, reducing stress concentrations and extending the fatigue life of the entire assembly.
Field data from mining operations shows that genuine XCMG planetary gear trains last up to 50% longer than aftermarket alternatives, dramatically reducing downtime and total cost of ownership.
The 860682035 Planetary Gear Train is the core of the ADT’s power transmission system, directly influencing machine traction, fuel consumption, and overall reliability.
Worn or damaged gear trains cause increased backlash, excessive noise, and inefficient power transfer, leading to higher fuel consumption and accelerated wear of bearings, shafts, and seals.
This genuine XCMG assembly restores original gear mesh accuracy, ensuring smooth, vibration‑free operation and optimal power delivery from the engine to the wheels.
A properly functioning planetary gear train reduces parasitic losses, meaning the engine uses less fuel to achieve the same output, directly improving operating costs.
Fleet operators have reported a 20% improvement in transmission reliability and a 12% reduction in fuel consumption after standardising on genuine XCMG planetary gear trains.
Regular inspection of gear teeth for pitting, wear, or cracks is essential; any signs of damage require immediate replacement to prevent catastrophic failure.
The 860682035 Planetary Gear Train is produced using advanced CNC gear cutting, grinding, and heat‑treating technologies to achieve the highest levels of precision and durability.
The forging process refines the grain structure of each gear blank, enhancing mechanical properties, followed by precision hobbing and shaping to create accurate involute tooth profiles.
XCMG’s engineering team has optimised the gear geometry – including tooth profile, helix angle, and root radius – to distribute loads evenly and minimise stress concentrations.
The precision grinding operation achieves a tooth accuracy of ISO Grade 6 or better, ensuring low noise and vibration while maximising tooth contact area for optimal load sharing.
All assemblies are 100% inspected for tooth profile, pitch error, and concentricity using coordinate measuring machines, guaranteeing they meet XCMG’s strict OEM tolerances.
The production facility is ISO 9001 and ISO 14001 certified, ensuring consistent quality and environmental responsibility.
The 860682035 Planetary Gear Train is crafted from SAE 8620 / 20MnCr5 alloy steel, which combines excellent hardenability with good core toughness, ideal for heavy‑duty gear applications.
The carburising process enriches the surface layer with carbon, followed by quenching and tempering to achieve a case hardness of 58‑62 HRC, providing a wear‑resistant surface.
The tough core (30‑38 HRC) absorbs impact loads without fracturing, protecting against shock from sudden torque spikes and wheel hop.
Shot peening introduces compressive residual stresses on the tooth surfaces, significantly improving bending fatigue strength and resistance to crack initiation.
Accelerated pitting tests show that the combination of carburising and shot peening extends gear life by over 60% compared to non‑peened components.
All materials are RoHS compliant and free from hazardous substances, meeting strict environmental standards.
The 860682035 Planetary Gear Train is designed for professional installation by experienced transmission technicians using appropriate tooling and procedures.
Begin by safely removing the transmission or final drive assembly from the machine, following the service manual for the specific model.
Disassemble the planetary carrier and carefully extract the old gear train, noting the orientation and positioning of the sun gear, planet gears, and ring gear.
Thoroughly clean the carrier, inspect all bearings, pins, and thrust washers for wear, and replace any damaged components.
