One New Aftermarket Replacement Final Drive Bull Gear Fits John Deere Crawler Dozers, Excavators, and Tractors

This aftermarket replacement bull gear fits the final drive assembly on Fits John Deere (Fits JD) 350-series crawler dozers, 690-series excavators, and the 990 tractor. The bull gear is the large ring gear in the final drive that receives torque from the pinion shaft and transmits it to the drive sprocket, delivering tractive power to the tracks. Replacing a worn or damaged bull gear restores proper final drive function and helps prevent costly drivetrain damage.
