Frequently Asked Questions

What Cat D3 undercarriage parts does Broken Tractor carry?

We carry single flange (281-8339) and double flange (281-8338) bottom rollers for the Cat D3, D3B, D3C, D3G and D3K, along with the 4K7038 track bolt for D3 series dozers. For the D3 Next Gen with SystemOne undercarriage, we offer wear plates 310-7375 and 310-7376. Fitment varies between D3 versions, so match the part number on your old part before ordering.

What undercarriage parts fit a Cat D3B?

For the Cat D3B, Broken Tractor carries single and double flange bottom rollers, the 6S7220 track adjuster idler plate, the 4K7038 track bolt, and track link pin seals 7K9203 and 8G3732. These same parts also list fitment for the D3C. Because two different pin seals fit the D3B, compare the number on your old seal or call (800) 909-7060 to confirm the right one.

What Cat D3G and D4G undercarriage parts do you offer?

The Cat D3G and D4G share several parts we carry, including the 281-8339 and 281-8338 bottom rollers, the 6S7220 track adjuster idler plate and the 4K7038 track bolt. Both models are also listed for Duo-Cone final drive seals 9G5343 and 6Y-0859. Since more than one seal fits these machines, match the part number on your existing seal to get the correct one.

What are the parts of a dozer undercarriage?

A dozer undercarriage is the track system the machine rides on, made up of track shoes, track links with pins and seals, bottom rollers, idlers and the bolts that hold the track together. For Caterpillar dozers, Broken Tractor offers track shoes, single and double flange bottom rollers, track adjuster idler plates, track link pin seals, track bolts, Duo-Cone final drive seals and SystemOne wear plates.

What track shoes fit a Cat D6 dozer?

We carry a 20 inch single grouser track shoe (CR2084/20-CAT) that fits the Cat D6C, D6D, D6E and D6G. For the Cat D5H and D5H XL, we also offer a 22 inch single grouser track pad (CR4392/22). Single grouser shoes are designed for standard ground conditions.
