IH construction equipment serial numbers & engine xrefs

62 posts in this topic

This thread contains IH construction equipment serial number lists and engine cross reference information. Excellent info for ascertaining the year of manufacture of your crawler tractor and the engine it uses, not to mention the other machines that use the same engine.

If you have questions about your machine, post them as new topics. If you have additional info pertaining to this topic, please feel free to add it.

Starting this off with this web site link to a set of very nice serial number lists.

Two thumbs up & an extra slice of raisin pie to Magic Mikey for putting up these numbers. My one finger would be worn to a nub after all that typing :o

I started this about ten years ago..., and gave up about 3 years ago. Because I was on dial up it was just to frustrating to try & post the pages I had on here & untill they created this section there really wasn't a good place to put it. Well YEA HA ,This section exists & I now have Hi Speed. so I will put the individual pages here for anyone who wishs to save a copy of the info for a particular machine(s).

I make no gaurantees that this info is "carved in stone accurate". I collected numbers from as many documents & publications as possible & cross referenced those numbers, using those that came up the same throughout them. The serial numbers should be fairly accurate, although the numbers for the very early machines ( ie T20, T&TD 30 & 40 ) varied widely depending on when/who published them. The hard numbers to varify were the horsepower & weight numbers, these seemed to be different no matter where I looked, I don't remember whose numbers I ended up using for these. Also just to clarify the weight under the heading Blade is for the blade attachment only, where as the weight under the heading loader is for the complete machine configured as a loader.

The complete document is in Microsoft Works spreadsheet format (the cheapo version of Excell) If anyone would like a copy of the complete document to play with, fill in the blanks, correct, or what ever, send me a PM or email with your email & I'll send you a copy.

Enjoy

Doug
