The Heavy Duty John Deere 550G Bulldozer Sprocket is a replacement undercarriage component designed to transfer drive power from the final drive to the track chain. As a critical part of the crawler undercarriage, the sprocket engages with the track bushings to drive the bulldozer and maintain consistent track movement.

John Deere identifies T104598 as an original drive sprocket compatible with the 550G, along with selected 450G, 455G, 555G, and 650G machines. This confirms the 550G application for this specific original part reference.

Xiamen Doozer supplies replacement sprockets for John Deere crawler bulldozers, with configurations selected according to the machine model, track chain, mounting arrangement, and operating conditions. The sprocket is manufactured to provide reliable tooth engagement and withstand repeated loads generated during pushing, grading, earthmoving, and other heavy-duty operations.

Different 550G undercarriage configurations can use different sprocket options. For example, aftermarket references identify a 25-tooth, 9-bolt-hole configuration for certain 550G applications, while other listings simply identify the component as a 550G sprocket. Therefore, tooth count, mounting-hole pattern, and dimensions should be confirmed against the existing sprocket and machine serial number before ordering.
