CAT D10 D10R D10T D10T2 Final Drive Group 110 2656 Heavy-Duty Mining Dozer Planetary Reducer

The Final Drive Group Assembly (P/N 110 2656) is the heavy-duty mechanical power-delivery core engineered specifically for Caterpillar’s D10 large track-type tractor fleet. Built for the 70+ ton crawler class, including the D10, D10R, D10T, and D10T2, this assembly utilizes a multi-stage planetary gear reduction system to handle extreme drawbar pull. Designed for CAT's signature elevated sprocket (high-drive) architecture, it isolates heavy torque delivery from ground-induced impact shock loads in aggressive mining and bulk earthmoving applications.

Maximizing Drawbar Tractive Force for Extreme Overburden The Caterpillar D10 series represents the global benchmark for heavy-duty mechanical pushing and ripping power. While the elevated sprocket design protects the steering clutches and final drives from direct ground impact, mud ingestion, and roller frame shocks, the internal planetary gear sets must still manage astronomical torsional loads. The 110 2656 final drive group is the ultimate mechanical torque multiplier that delivers power from the drive axles directly to the track segments.

Our premium replacement final drive components and full assemblies are built to eliminate common failure points under severe conditions. Featuring deep case-hardened planet gears, precision-ground sun shafts, and robust planet carriers, this unit resists gear tooth pitting and fatigue failure during heavy slot dozing or hard rock ripping. Upgrading a worn or noisy unit with our precision-fit 110 2656 final drive group fully restores the machine's factory drawbar efficiency and prevents sudden drivetrain downtime.

• Global Mining & Quarries: Optimized for high-uptime extraction environments across North America, Australia, and Africa. Ideal for mass overburden stripping, mine site road maintenance, and heavy reclamation work.

• Extreme Thermal Climates: Built with specialized premium sealing compounds to handle wide temperature fluctuations—from the intense radiant heat of open-cast desert pits to sub-zero cold starts in northern coal operations.

• Civil Infrastructure & Aggregate: Engineered to survive repetitive high-shock impacts when pioneering rocky mass cuts, clearing hard aggregates, or managing heavy pipeline right-of-ways.

The High-Torque Lubrication Standard: Unlike excavator drives which are combined hydraulic systems, dozer final drives rely entirely on a dense gear oil film to prevent extreme tooth-to-tooth micro-welding. Always use premium CAT FDAO (Final Drive and Axle Oil) or an equivalent specialized high-viscosity gear lubricant.

• S.O.S. Scheduled Oil Sampling: Sample the final drive oil every 250 operating hours. Monitor parts-per-million (PPM) counts of iron, copper, and lead. A sudden rise in copper indicates thrust washer degradation, which must be addressed before it causes gear misalignment.

• Magnetic Drain Plug Inspections: Clean and inspect the magnetic plug at every oil drain interval. While fine metallic silt is normal, distinct metallic flakes or chunking mean subsurface gear spalling has occurred—shut down the asset immediately to save the planetary carriers.

• Sprocket Segment Bolt Lifecycle: The high torque transferred by the 110 2656 drive will stretch sprocket segment hardware over time. Never reuse old segment bolts. Always use new Grade 12.9 fasteners, torque to factory specifications, and execute the final torque-turn sequence to prevent loose segments from destroying the drive hub threads.

Guangzhou Tieqi Construction Machinery Co., Ltd. (IRON CAVALRY) is strategically located in Guangzhou's Huangpu District, approximately an hour from Baiyun International Airport. We have been a dedicated specialist in engineering machinery hydraulics for nearly 15 years.

Driven by our core values of "Pragmatism and Progress," we are committed to delivering practical solutions and upholding our responsibilities. This principle-driven approach defines all our operations and client partnerships.

In China's excavator hydraulic assembly sector, our efficient execution and rigorous approach to manufacturing every product to meet over 95% of original performance specifications have built widespread trust. This has made us a destination for industry peers and clients seeking knowledge and reliable supply.

Our capability is backed by a ready inventory of over 500 assembly types, providing access to more than 6,000 different parts. Hydraulic pump, control valve, travel, and swing assemblies are our core products, with a distinct advantage in large mining excavator components and hard-to-find items.

Our 4,000-square-meter factory in Guangzhou is equipped for professional manufacturing, precision assembly, rigorous testing, and quality certification, ensuring reliable performance and timely delivery for every order.

For large items, we use sturdy plywood crates secured with metal fasteners for added stability. Inside, the products are cushioned with bubble wrap and secured with wooden braces, while special attention is given to protecting vulnerable parts. Externally, the crates are reinforced with high-strength PET plastic strapping and wrapped in highly waterproof black film.
