Frequently Asked Questions

What rubber tracks fit a Cat 301.8?

Broken Tractor carries 230 millimeter rubber tracks for the Cat 301.8 in both long pitch and short pitch styles. The long pitch track is SKU Caterpillar-RT100204-WI, and short pitch options include SKU Caterpillar-RT100204S-WI and SKU Caterpillar-RT100206S-WI. Long pitch and short pitch tracks are not interchangeable, so check the pitch, width and link count on your current track before ordering.

What Cat excavator rubber tracks does Broken Tractor carry?

We carry conventional, short pitch, long pitch and interchangeable rubber tracks for Cat mini and compact excavators, in widths from 180 millimeters up to 400 millimeters. Coverage runs from micro machines like the 300.9D and 301 series through the 302 to 306 series, plus Cat MM, ME, MH, MS, MX, MXR and NS models. Bolt-on double grouser rubber pads are also available for select 303 to 306 series machines.

How do I know which rubber track fits my Cat mini excavator?

Match the track pitch, width and link count on your existing track, then confirm it against your exact Cat model. Cat model designations change by generation, so the right track can differ even between similar names. For example, the 303 CR 1st Gen and 2nd Gen do not share the same set of track options. If you are unsure, call the Broken Tractor parts team at (800) 909-7060 to confirm fitment before you order.

What is the difference between Cat rubber tracks and bolt-on rubber pads?

Rubber tracks are complete continuous tracks, while bolt-on rubber pads attach individually to the track. Broken Tractor offers bolt-on pads for 303 to 306 series machines that work on paved or sensitive surfaces. Examples are the 300 millimeter double grouser pad for models such as the 303.5E2, 304E CR and 303 CR, and the 400 millimeter pad for the 305.5E CR, 305E2 CR, 306E, 306 CR and 305.5D CR.

What other undercarriage parts are available for Cat mini excavator rubber tracks?

Broken Tractor also carries top carrier track rollers and drive sprockets for select Cat mini excavators. The top carrier roller, SKU 4392416-C, fits the 303CR, 303.5C, 304CR and 305CR. The 19 tooth, 12 bolt drive sprocket, part number 260-6341, fits models including the 304C CR, 305C CR, 305.5D, 305E2 CR and 305.5E2 CR, so match the part number to your machine before ordering.
