Caterpillar 247-1459 Planetary Gear Assembly

The 247-1459 planetary gear is a critical component within the final drive assembly of Caterpillar small track-type tractors. Manufactured to OEM specifications, this 44-tooth gear transmits rotational force from the sun gear to the ring gear, enabling speed reduction and torque multiplication for track propulsion. Constructed from forged alloy steel with case-hardened gear teeth, the component withstands high contact stresses and shock loads inherent in dozing and grading applications. It serves as a direct replacement for Caterpillar OEM part numbers 247-1459 and 2471459, compatible with D3K, D3K2, D4K, D4K2, D5K, D5K2, and Next Generation D1, D2, D3 models equipped with C4.4 engines. Precision machining ensures correct backlash and meshing alignment with mating sun gears and planetary shafts.
