Frequently Asked Questions

What are the parts of an excavator undercarriage?

An excavator undercarriage includes the rubber tracks or steel track shoes, drive sprockets, top carrier rollers, and the track tensioner hardware. Broken Tractor carries these components for Bobcat compact and mini excavators, including conventional, short pitch, and long pitch rubber tracks, bolt-on grouser pads, sprockets, rollers, and track shoe bolt and nut kits.

What undercarriage parts fit a Bobcat 331?

For the Bobcat 331 we carry a 320 mm short pitch rubber track (SKU Bobcat-RT100605A-WI), a 300 mm short pitch rubber track (SKU Bobcat-RT100405K-WI), a 300 mm bolt-on double grouser rubber pad (SKU Bobcat-DHR101X300B), a top carrier track roller (SKU 4392416-B), a drive sprocket (SKU 6811940), and a track tensioner grease fitting (SKU 6655752). Because fitment can vary by build, match the part number or confirm with our parts team.

How do I find the right rubber track size for my Bobcat mini excavator?

Match your machine model to the track width and pitch profile, since Bobcat excavators use tracks from 180 mm up to 400 mm in conventional, short pitch, and long pitch profiles. For example, we offer a 250 mm track for the X220 and X320, a 320 mm track for the X125, and a 400 mm short pitch track for the E60, E62, and E63. If you are unsure of your width or pitch, call our parts team at (800) 909-7060 to confirm.

What is the difference between short pitch and conventional rubber tracks for Bobcat excavators?

Pitch refers to the spacing of the internal drive lugs on the track, and it must match your machine's sprocket and undercarriage. Broken Tractor carries conventional, short pitch, and long pitch profiles, and some Bobcat models are offered in more than one profile, such as the 320 and 322 available in both short pitch and long pitch 230 mm tracks. Match the part number to your machine so the track engages the sprocket correctly.

Do you carry drive sprockets for Bobcat mini excavators?

Yes, we carry Bobcat excavator drive sprockets, including part 7199008 for the E45, E50, E55, E55Z, and E60, and sprocket 6811940 for models such as the 231, 325, 328, 331, and 334. Confirm the tooth count and bolt pattern match your machine, or contact our parts team if you need help verifying fitment.
