One New Aftermarket Replacement Final Drive Sun Gear for Caterpillar (Cat) Construction Equipment
This 18-tooth planetary sun gear is a key component of the final drive assembly on Caterpillar (Cat) construction equipment. The sun gear sits at the center of the planetary gear set and transmits rotational power from the travel motor through the planetary carrier to drive the tracks. Worn or chipped sun gear teeth cause reduced travel speed, uneven track movement, and accelerated wear on mating planet gears -- replacing this gear restores proper power distribution through the final drive.
Specifications
- Teeth: 18 (sun gear) x 37 (total gear profile per Cat OEM data)
- Location: Final drive planetary gear set
- Qty: 1
Compatible Models
Caterpillar: Verify fitment against your machine model and serial number before ordering -- final drive components can vary within the same model line depending on production date and build configuration.
