Frequently Asked Questions

How do I look up Caterpillar parts by serial number?

Matching parts by serial number helps confirm the correct fit, since many Cat components changed across production runs. Locate the serial number on your machine data plate and compare it to the part fitment, or contact our parts team to verify. Call (800) 909-7060 for help confirming the right part.

Do you carry aftermarket Caterpillar replacement parts?

Yes, Broken Tractor offers both aftermarket replacement parts and quality used Cat components. Aftermarket parts provide a lower cost option, while used salvage parts are ideal for older machines. Both are matched to fit the model and serial range you provide.

Can you help me find the right Caterpillar part if I do not have a part number?

Yes, our parts team can help identify the correct component using your machine model, serial number, and a description of the part. Sharing photos of the old part also helps us confirm the match before you order.
