What's the difference in a 71-72 and 73-74 cc129 starter gen
Posted January 16, 2018 - 05:31 PM
My cc129 has no readable tags to tell a year engine was replaced with a oe replacement. And the original starter generator is long gone. I tryed to get a used one but waisted my money on the wrong rotation.

Or if anyone can help with a part number for a new one that would help!

Looked in my old parts books and the Delco number for the starter/generator was 1101691 and said to use 1101692 and IH gave it their number IH-529721-R92. That number is the same for all the wide frame Cadets and according to the where used list in the back of the parts book it's also the same for the 73, 106, 107, 126, 127, and 147.
As for differences for the years your asking about according to the parts book the only difference is the armature. They give 2 different numbers for it but everything else is the same in them. These guys list both Delco numbers: https://www.dbelectr...01996-9190.html According to them the different armature numbers are due to the fact that the 691 is 15 amp and the 692 is 12. From that I would say the 71-72 is probably 15 amp and the 72-74 is 12 amp.
Basically as long as you're positive it came off a Cub Cadet any starter/generator will bolt on and work, doesn't matter what model tractor it came from. As far as I can remember there is 2 differences in the starter/generators from 1961 to 1974 when they stopped using them. The first is the early Cadets up to around 1969 had a ball bearing on the back end of them then changed to a bushing and the other is the size of the pulley changed. I don't remember if they early one was smaller or bigger, but they changed it on the later ones for easier starting. Hope this helps. Stewart
