Frequently Asked Questions

What size rubber track fits a Komatsu PC35MR-1?

The Komatsu PC35MR-1 takes a 300 mm short pitch rubber track, which Broken Tractor carries as SKU Komatsu-RT100407K-WI. The same track also fits the PC20-2, PC20-6, PC25-1, PC25-2, PC25-7, PC30-6, PC30-7, PC30MR-1, PC30MRX-1, PC30R, PC30R-8, PC30UU-3, PC35, PC35R, PC35R-8, PC35MRX-1A, PC38, PC38-2, PC38-2 Avance R, PC38UU-2 and PC38UU-3. Match your model number and current track width before ordering.

What rubber track fits a Komatsu PC50MR-2?

The Komatsu PC50MR-2 uses a 400 mm short pitch narrow guide rubber track, SKU Komatsu-RT100019A-WI. That narrow guide track also fits the PC40MR-2, PC45MR-3, PC45MR-5, PC50MR, PC55MR-2, PC55MR-3, PC55MR-5 and PC58UU-3. The standard PC50, PC50-1 and PC50UU-1 take a different 400 mm short pitch track, SKU Komatsu-RT100017A-WI, so check the exact model designation on your machine.

Why are there two rubber track options for the Komatsu PC28 and PC15-1?

Broken Tractor lists more than one track for some Komatsu models because the width or pitch can differ within the same model range. The PC28 appears under both a 320 mm conventional track (SKU Komatsu-RTC00606-WI) and a 300 mm short pitch track (SKU Komatsu-RT100405K-WI), and the PC15-1 has two 320 mm conventional options (SKU Komatsu-RTC00606-WI and Komatsu-RTC00607-WI). Measure the width of your current track and check any markings on it, then call (800) 909-7060 if you need help choosing the right one.

Which Komatsu mini excavators use a conventional rubber track instead of a short pitch track?

Broken Tractor carries conventional rubber tracks for the Komatsu PC02 series, PC03 series and PC09 at 180 mm, the PC05-1 and PC05-5 at 230 mm, and the PC08 series and PC15MR-1 at 200 mm. Conventional tracks are also offered for the PC15FR-1 at 230 mm and for the PC10-5, PC15-1, PC28, PC28-1, CD23 and CD30R at 320 mm. Short pitch tracks cover models such as the PC15MRX-1, PC18MR-2, PC26MR-3, PC27MR series and the PC20 through PC58 machines.

Do you carry top carrier rollers and drive sprockets for Komatsu PC35MR excavators?

Yes, Broken Tractor offers a top carrier track roller, SKU 4392416-H, listed to fit the Komatsu PC30MR, PC35MR, PC40MR and PC50MR. We also carry a drive sprocket, part number 2055869, that fits the Komatsu PC27MR-2, PC27MR-3, PC27R-8, PC30MR-2, PC30UU-3, PC35MR-2, PC35MR-3 and PC35MR-5. Because fitment can change between machine versions, match the part number from your old part or confirm with our parts team before ordering.
