Used parts can be a practical option when you want to keep an older crawler working without paying for new.

What Caterpillar D4 dozer parts do you carry?

We carry parts for the D4 series, including the D4, D4C, D4D, D4E, D4G, D4H and D4K. Part groups include undercarriage, hydraulic cylinders and hoses, final drive and steering clutch components, and engine accessories like filters and belts.

Can I still get parts for old Caterpillar dozers?

Yes, Broken Tractor carries parts for older Cat dozer models as well as current series. Coverage includes lettered models such as the D6C, D7E, D8H and D9G, along with the base D3 through D9 models. Our used parts selection can help with older machines, and our staff can match parts to your serial number.

Are there Caterpillar dozer parts near me?

Broken Tractor ships Cat dozer parts nationwide, so you can order from anywhere in the U.S. We offer fast shipping from our locations in Baton Rouge, Louisiana and Kimbolton, Ohio. That gives you access to a wide selection of new and used parts even if no local dealer has what you need.

What do I need to order the right Cat dozer part?

You need your machine's serial number and series prefix. Cat dozers within the same series can use different parts depending on the serial range, so the model name alone may not be enough. Matching the part number from your old part or giving our staff your serial number helps make sure the replacement fits.
