Found Serial Number on D7 - Please help I.D.

What part of MN? There are several of us in Mn. Maybe one of us is close and can help out. D7C 17A series. Should be a 1958. 123-125hp.

Cat is in Ortonville, Mn. Boy, if anybody is close, it would be great to have an expert come and take a look at it, or at least provide me with a phone number so we could talk.

Thanks, Jim 612-963-2758

So I found the number 17A10407.

Is there a model number for the pony motor? I am so new to the Cat world, I see all these various model numbers, say for example, a D7 17A, but when referencing just those numbers, I find that they apply to many many years of Cat models. Thus, thank you for informing me that my cat looks like it may be a 1958 123-125 hp. But, as I understand it, the number "17A10407" should tell me everything I need to know about my cat, including, the specs, what op/svc manual I need to get, the pony motor model and specs, and how to order parts for the pony and the cat.

Thanks again, Jim

Your D17A serial number is the magic number that will get you all the information you need. That number will let you know which books you will need for parts and service manuals. Opposite side of the stated for me.

Kracked1, thanks for feedback.

I was first in contact with Bill Amaducci (VP ACMOC), several days ago, who told me where to find serial number. He said that once I got that to him, he could provide me with all the info I needed. Since I have not heard from him in several days, I figured he could be on vacation, etc., thus I re-posted today in general discussion forum. I am sure he will get back to me soon.

Thanks again.

it appears to be a 1958 machine:

Ebay is a good start for manuals
https://www.ebay.com/sch/i.html?_odkw=Caterpillar+D7&_osacat=0&_from=R40&_trksid=m570.l1313&_nkw=Caterpillar+D7+17a&_sacat=0

or Cat
https://www.cat.com/en_US/support/maintenance/service-manuals.html

or Jensales
https://www.jensales.com/products/caterpillar-d7-crawler-operators-manual-sn-17a-and-up.html

Jensales is copies of manuals. I have had their copies be not very good/clear.

looks like cat service manuals used range from 45.oo and up on ebay.

Go ahead and get the real thing instead of copies but every persons budget is different.

The poney motor has no model and for order parts you give the poney motor parts number and he is rear carburator and if I can help am still have some poney parts and more
