Sprockets & Segments
Replacement Sprockets and Segments
Drive sprockets and bolt-on segments transfer power from the final drive into the track chain. Tooth profile, pitch, bolt pattern, machine model, serial range, and compatibility with the installed chain all affect fitment.
Where Sprockets and Segments Are Used
- Excavators and mini excavators
- Crawler dozers and loaders
- Other tracked equipment with chain-driven undercarriages
Use the undercarriage parts hub to review track chains, rollers, idlers, and shoes. Sprockets and chains wear together, so replacing a new component against a severely worn mating surface can shorten service life.
Confirm the Correct Drive Component
Provide the machine make, model, serial number, tooth count, bolt pattern, dimensions, part numbers, and photos through the Part Finder.
Match Sprocket Teeth to the Track Chain
Check Pitch and Wear Pattern
Hooked teeth, sharp points, uneven wear, and poor chain engagement can indicate that sprockets, segments, and rails should be evaluated together.
