CAT D5 D5C III D5G Final Drive Group 113 1760 Compact Dozer Planetary Reducer

The Final Drive Group Assembly (P/N 113 1760) is the high-torque, mechanical power-delivery core engineered specifically for Caterpillar’s small track-type tractor and loader fleet. Built for the 8 to 10-ton crawler class, including the D5, D5C Series III, D5G (XL / LGP configurations), and the 939C track loader, this unit utilizes a multi-stage gear reduction system to handle rugged drawbar demands. It translates core power directly to the tracks, providing the relentless pushing power and fine-grading stability required for high-precision site development.

Restoring Finish-Grading Power and Machine Agility The Caterpillar D5C Series III and D5G are industry benchmarks for fine grading, residential site preparation, and light clearing operations. Because their value relies entirely on smooth maneuvering and consistent ground push, a worn final drive can completely ruin site productivity. The 113 1760 final drive group serves as the vital torque multiplier at the end of the power train assembly, ensuring engine power is efficiently converted into aggressive drawbar pull.

Over thousands of operational hours, the relentless forward-to-reverse cycling of dozing puts massive shearing forces on the internal spur and planetary gear sets. Our premium replacement final drive gearboxes are engineered to eliminate tracking lag, noise, and power loss. Built with induction-hardened gears and high-load tapered roller bearings, this assembly restores factory-standard climbing ability and guarantees zero tracking drift across unstable soil conditions.

• North America & Europe: Essential for the Residential Construction, Landscaping, and Finish Grading sectors where dozers experience constant high-frequency forward/reverse directional shifts.

• Southeast Asia & Central America: Tailored for Agricultural Engineering and Land Clearing projects. Equipped with ultra-robust mechanical floating seals to prevent the ingestion of loose volcanic soil, wet paddy mud, and sand.

• Global Rental Fleets: Offers a reliable, highly cost-effective replacement solution to minimize fleet downtime, quickly returning the asset to service with long-term component lifecycle reliability.

• Gear Oil Cleansing Intervals: Dozer final drives endure extreme load shearing. Change the planetary gear oil every 500 operating hours. If the fluid looks "milky," water has breached the Duo-Cone seals—reseal the unit immediately to prevent severe bearing race pitting.

• Magnetic Plug Diagnostics: Inspect and clean the magnetic drain plugs at every preventative maintenance service. While microscopic steel fuzz is normal, distinct metallic shards or flakes mean gear spalling has occurred—shut down the asset immediately to protect the planetary carriers.

• Sprocket Segment Maintenance: The D5G/D5C utilizes bolt-on sprocket segments. The intense torsional forces transferred by the 113 1760 drive will stretch mounting hardware over time. Never reuse old bolts; install new Grade 10.9 or 12.9 fasteners with a high-strength thread locker to prevent the segments from tearing out the hub threads.

• Hydraulic Motor Cohesion: Ensure the matching hydraulic travel motor is performing to proper system relief pressure settings. Low hydraulic flow can occasionally cause a false diagnosis of mechanical binding inside the final drive gearbox.

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.
