Yes, I agree CNH needs and has to make a profit on parts. But when you see the old generation makin a decent happy style of living off of repairing small items...starters, alternators, small engines, propane stuff. You know there is a hell of a mark up, and desire to change stuff just for the sake of change. Mainly so people can not find it, and have to get it OEM you know there is a problem. I know I personally stock close to a dozen alternators... from Niehoff brushless 1480, Many a delco both small and large frame...3 voltage levels, swing arm brushes, one wire, engergized by ign, 3large frame delco, a large frame bosch like on combines, 2-3 Nippondenso (JD),Even have a large frame leece-Neville on hand. And I bet I do not have a $1006 in all of these. One of my large frame Delco came out of a dumpster at one of my unit train grain delivery sites. Please be stupid and stick some more in the dumpsters, I always enjoy a good find. Heck the other Day I seen a whole 55 gal barrel full of no doubt dead alternators. Heck I was even so lucky to find a Ford Powerstroke alt from a guy for $10, Naturally took it to my repair man, was in excellent shape, not a thing wrong. You guys are crazy if you think CNH is the only place that can rebuild their current production alternators. Heck in your case probably only need to stock one version, One-wire, I'd ask rotation so as to know whether or not have correct fan to cool. (This could be this gentleman's problem) Bet your running maintance free batteries so I know what voltage level to choose if I liked you, and bingo, long as know how to disable the idiot light and buzzer you would be good to go, just remember to unhook in the off season so your self-exciting one wire does not slowly drain your batteries, a one wire does pull a few milli-amps, just like a clock. Think of it this way with-out tearing them down, how do you know what is killing them, if there was a way to improve a selection for you app. Is the diod-trio a problem, are the bearing failing, Is the stator flying apart, what is going on that they are junk. Only way to know is to have some good ole boy diagnose and test, bet you can not ask your parts man to let you know what parts it needed. Vibration, heat, dirt, chaff, all play a part, something needs fixed. May have to put a venturi aspirator on the alternator, just like you have on your air cleaner. Just go plug that baby off and see how long your air cleaner will go w_o plugging off.
