I purchaced a very nice lot of new old stock IH parts from a dealer that had went out of business years ago. I am going through the parts slowly, logging the parts numbers and taking inventory of how many of each part. I have found some parts numbers as to there application, on the CaseIH website parts number search. A lot of these parts are probably obsolete, and when I do a search of the number, it comes up most of the time "no matches". Does anyone know of a parts CD that would have the older parts numbers on it? Thanks for any information. I got a bunch of parts manuals also, but it would take a great deal of time to check all the parts numbers the old way.
