Home › Knowledge Base › Cat Parts Quotes Made Fast: Part Number vs Serial Number vs Photo
Quick answer:Fastest quote: CAT part number. Most accurate for engine and driveline parts: model + serial number — the same model can take different parts across serial ranges. No numbers left? Three photos lock the part.

Engine parts warning: on C4.4 / C6.4 / C7.1 / C9 engines, injectors, high-pressure pumps and ECUs can differ across serial ranges of the same model. Sending the serial number avoids a wrong-part round trip. See our serial-prefix guide in this knowledge base.

FAQ

Can you quote with only the machine model?

Yes — send model + serial number or photos, we reverse-look-up the factory configuration and quote, usually the same day.

My old part number is half worn off.

Send a clear photo of the stamp, or the model + serial number; superseded CAT numbers are cross-matched on our side.

How fast for urgent parts?

In-stock parts are quoted and can ship the same day once details are complete; air-freight transit is quoted with the offer.
