The genuine XCMG Reducer with OEM number 800172704 is a high-performance power transmission component engineered for XCMG articulated dump trucks and heavy off-highway machinery. This reducer delivers reliable torque conversion and speed reduction, ensuring optimal drivetrain efficiency under extreme loads and harsh operating conditions.
The XCMG reducer 800172704 is built to withstand the punishing demands of mining, quarrying, and heavy construction. Its planetary gear train distributes load across multiple teeth, reducing stress per gear tooth and eliminating premature failure.
Each unit undergoes 100% dyno testing before leaving the factory. Test results confirm that the 800172704 reducer maintains constant torque output even after 5,000 thermal cycles from -30°C to +80°C.
All internal gears in OEM 800172704 are carburized and hardened to 58-62 HRC, then finish-ground to AGMA Class 12 precision. This produces a mirror-like surface finish that minimizes friction and wear over decades of operation.
The housing is stress-relieved after casting to prevent distortion under heavy shock loads. Finite element analysis (FEA) optimizes rib placement for maximum stiffness-to-weight ratio.
Dust and water ingress are the main killers of heavy-duty reducers. The 800172704 features a triple labyrinth seal combined with a spring-loaded FKM lip seal. This system keeps abrasive particles out even when the axle is submerged in muddy water.
A magnetic drain plug captures ferrous wear debris, allowing technicians to monitor internal health during oil changes. Breather vents include a desiccant filter to prevent moisture condensation.
Beyond AD-series articulated dump trucks, the 800172704 reducer also fits XCMG wheel loaders (LW700KN, LW900KN) and certain motor graders when using optional adapter plates. Always verify your equipment’s original part number before ordering.
For fleet managers, standardizing on OEM 800172704 reduces inventory complexity. The same reducer can be used on front, center, or rear axles in most XCMG rigid dump trucks manufactured after 2015.
Proper installation of reducer 800172704 begins with cleaning the mounting flange and inspecting the input shaft splines. Apply a thin layer of anti-seize compound to all bolt threads and torque mounting bolts to 450 N·m in a cross pattern.
Fill with approved synthetic or mineral gear oil up to the middle of the sight glass. Run the unit for 10 minutes at low speed, then re-check oil level. First oil change at 500 hours, then every 2,000 hours or annually.
Always replace the seal ring and o-rings when reinstalling the reducer. Using genuine XCMG gaskets prevents leaks and ensures proper crush tolerance. Never reuse old locking nuts or spring washers.
Field data from 120 XCMG AD60 trucks shows that using genuine OEM reducers (800172704) reduces drivetrain-related downtime by 62% compared to rebuilt or aftermarket units. Each avoided breakdown saves approximately $8,500 in lost production and repair costs.
Furthermore, the superior efficiency of original gearing reduces fuel consumption by 1.8% on average. For a fleet hauling 1 million tons per year, this translates to over 12,000 liters of diesel saved annually.
Every XCMG reducer 800172704 comes with a laser-etched serial number and full traceability report. This includes raw material certificates, heat lot numbers, and final inspection data. Counterfeit reducers often lack this documentation and fail catastrophically.
All genuine components are backed by XCMG’s worldwide warranty. By choosing OEM 800172704, you protect your equipment investment, maintain resale value, and ensure compliance with factory maintenance schedules.
