OEM 800374184 The XCMG Gear (800374184) is a genuine OEM precision‑cut power transmission component engineered to transfer torque and motion within the transmissions, final drives, and auxiliary gearboxes of XCMG articulated dump trucks. This high‑strength gear, identified by part number 800374184, is the backbone of the ADT’s driveline, ensuring reliable, efficient power delivery under the extreme loads and continuous duty cycles typical of mining and construction operations.
Manufactured from high‑quality case‑hardening alloy steel with precision‑ground tooth profiles, the 800374184 gear offers exceptional 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 shock loads.
The 800374184 gear 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 800374184 Gear is a precision‑ground power transmission component that ensures efficient torque transfer between shafts, enabling smooth acceleration, deceleration, and load‑sharing in XCMG ADT drivetrains.
In articulated dump trucks, gears operate under high loads and continuous cycling, transmitting engine torque through the transmission, transfer case, and final drives to the wheels.
This genuine XCMG gear is manufactured from case‑hardening alloy steel with a precision‑ground involute tooth profile, ensuring accurate meshing with mating gears, minimising backlash, and reducing noise.
Its carburised and hardened surface provides a wear‑resistant layer that resists pitting and spalling, while the tough core absorbs shock loads, preventing tooth breakage under extreme conditions.
The shot‑peened surface further enhances fatigue resistance by inducing compressive residual stresses, significantly extending the gear’s service life and reliability.
Field data from mining operations shows that genuine XCMG gears last up to 50% longer than aftermarket alternatives, reducing downtime and total cost of ownership.
The 800374184 Gear is a key element in the ADT’s power transmission chain, directly affecting vehicle traction, fuel economy, and overall operational reliability.
Worn or damaged gears cause increased backlash, noise, and vibration, leading to inefficient power transfer, higher fuel consumption, and accelerated wear of bearings and seals.
This genuine XCMG gear restores original tooth geometry and surface integrity, ensuring smooth, quiet operation and optimal power transmission, reducing parasitic losses.
A properly functioning gear set also minimises shock loads on other driveline components, extending the life of the entire transmission and final drive assembly.
Fleet operators have reported a 20% improvement in transmission reliability and a 10% reduction in fuel consumption after standardising on genuine XCMG gears.
Regular inspection of gear teeth for pitting, wear, or cracking is essential; any signs of damage require immediate replacement to avoid catastrophic failure.
The 800374184 Gear is produced using advanced CNC hobbing, shaping, and grinding technologies, ensuring precise tooth geometry and consistent quality across all production batches.
The forging process refines the grain structure, enhancing mechanical properties, followed by precision machining to achieve the required tooth profile, pitch, and lead accuracy.
XCMG’s engineering team has optimised the gear’s micro‑geometry – including tooth tip relief and root fillet radius – to reduce stress concentrations and improve load distribution.
The precision grinding operation achieves a tooth accuracy of ISO Grade 6 or better, ensuring low noise and vibration while maximising tooth contact area.
All gears undergo 100% inspection using coordinate measuring machines, with sample units subjected to hardness testing, metallurgical analysis, and gear roll testing.
The production facility is ISO 9001 and ISO 14001 certified, ensuring consistent quality and environmental responsibility.
The 800374184 Gear 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 800374184 Gear is designed for professional installation by experienced transmission technicians, using appropriate tooling and following established procedures.
Begin by safely removing the transmission or final drive assembly, then disassemble the gear train to access the gear, noting its position and orientation.
Carefully extract the old gear, inspect the shaft and mating gears for wear or damage, and clean all components thoroughly with a suitable solvent.
Install the new 800374184 gear using proper pressing techniques and correct shimming to ensure correct backlash and tooth contact pattern, as per the service manual.
Reassemble the gear train, torque all fasteners to specification, and refill with the recommended lubricant, then test for smooth operation and correct gear engagement.
A typical gear replacement can be completed in 2‑4 hours, restoring driveline performance and preventing further damage to mating components.
Investing in the 800374184 Gear delivers substantial long‑term savings by preventing catastrophic driveline failures, reducing fuel consumption, and extending component life.
A broken gear can shatter and damage the entire gearbox, with repair costs often exceeding $15,000 – this genuine gear prevents that risk.
By maintaining precise tooth engagement, the gear reduces internal friction and heat generation, improving transmission efficiency and fuel economy by up to 3‑5%.
Reduced wear on mating gears and bearings also extends their service life, lowering overall maintenance costs.
