OEM 800374315 The XCMG Gear Ring (800374315) is a genuine OEM precision‑cut internal ring gear engineered to serve as the stationary or driven element in planetary gear sets within the final drives, transmissions, and swing drives of XCMG articulated dump trucks. This high‑strength gear ring, identified by part number 800374315, is designed to mesh with planet gears and transmit high torque loads with exceptional durability, ensuring reliable power distribution and smooth operation in the most demanding mining and construction applications.
Manufactured from high‑quality case‑hardening alloy steel with precision‑ground tooth profiles, the 800374315 gear ring offers excellent wear resistance, high load‑carrying capacity, and extended fatigue life. Its advanced heat treatment and shot‑peened surface deliver superior resistance to pitting, spalling, and tooth breakage, even under extreme shock loads and continuous heavy‑duty service.
The 800374315 gear ring is fully compatible with XCMG ADT series, providing a direct replacement solution that restores original driveline efficiency, reduces noise, and ensures smooth power transmission – keeping your fleet productive and reliable.
The 800374315 Gear Ring is a precision‑ground internal gear designed to serve as the stationary or driven element in planetary gear sets, providing the reaction force necessary for torque multiplication and power distribution in XCMG ADT final drives and transmissions.
Planetary gears are fundamental to heavy‑duty drivelines because they distribute torque across multiple planet gears, reducing the load on each tooth and enabling compact, high‑torque designs that are essential for off‑road hauling.
This genuine XCMG gear ring is manufactured from case‑hardening alloy steel, with teeth precisely ground to ensure accurate mesh with planet gears, minimising backlash, noise, and vibration.
Its carburised and hardened surface provides a wear‑resistant outer layer that resists pitting and spalling, while the tough core absorbs shock loads from sudden torque changes during gear shifts or rough terrain.
The shot‑peened surface further enhances fatigue resistance, extending the gear’s service life and reducing the risk of tooth breakage under extreme conditions.
Field data shows that genuine XCMG gear rings last up to 50% longer than aftermarket alternatives in identical mining conditions, significantly lowering total ownership costs.
The 800374315 Gear Ring is the heart of the planetary drive system, responsible for transferring the engine’s power efficiently to the wheels, directly impacting machine traction, fuel economy, and overall reliability.
Worn or damaged gear rings cause increased backlash, erratic shifting, elevated noise, and eventual transmission failure – costly repairs that can idle a machine for days.
This genuine XCMG component restores original gear mesh accuracy, ensuring smooth power flow, precise gear engagement, and optimal driveline efficiency.
A properly functioning gear ring 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 components.
Regular inspection of gear ring teeth for pitting, wear, or cracks is essential; any signs of distress warrant immediate replacement to prevent cascading failure.
The 800374315 Gear Ring is manufactured using state‑of‑the‑art gear cutting, grinding, and heat‑treating processes to achieve the highest levels of precision and durability.
The forging process produces a refined grain structure that improves mechanical properties, followed by CNC hobbing and shaping to create accurate tooth profiles.
XCMG’s engineering team has optimised the gear’s tooth geometry to reduce stress concentrations and improve load‑sharing with planet gears, enhancing overall planetary reliability.
The precision grinding operation achieves a tooth accuracy of ISO Grade 6, ensuring low noise and vibration while maximising contact area for even load distribution.
All gears 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 800374315 Gear Ring is made from SAE 8620 / 20MnCr5 alloy steel, which combines excellent hardenability with good core toughness, ideal for heavy‑duty gear applications.
The carburising process diffuses carbon into the surface layer, 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 during shifting or wheel hop.
Shot peening introduces compressive residual stresses on the tooth surfaces, significantly improving 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 800374315 Gear Ring is designed for professional installation by experienced driveline technicians using appropriate tooling and procedures.
Begin by safely removing the planetary gear set from the transmission or final drive, following the service manual for the specific machine model.
Disassemble the planetary carrier and carefully extract the old gear ring, noting its orientation and any shims or spacers for correct reassembly.
Thoroughly clean the housing and inspect the carrier and planet gears for wear or damage; replace any worn planet bearings or pins.
Install the new 800374315 gear ring, ensuring it is correctly aligned and fully seated, then reassemble the planetary set and verify end‑float is within specification.
A complete gear ring replacement typically takes 3‑5 hours, restoring transmission performance and preventing costly downtime.
Investing in the 800374315 Gear Ring delivers substantial long‑term savings by preventing catastrophic transmission failures, reducing fuel consumption, and extending component life.
