Like it says what's the difference?


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.

I'll start off by saying I'm no Cub Cadet expert. I have been around a lot of them. I've owned twenty or more. I still own several. Your question is a little unclear. I'll assume 71 - 72 refers to the year and not the model. 1971, 1972would be the last of the narrow frames, 73, 106, 107, 126, 127, 147. They had a starter generator like most all the earlier cubs. Their rear bearing was a ball bearing. 1973, 1974 was the first of the wide frames including your 129. Their starter generator had an aluminum rear end, containing a bronze bushing. The generators were typically painted black, the earlier were yellow. Hope this helps.

I want to know the difference in generators from the years 71-72 and 72-74. I found a source of a new generator and they have years (71-74 listed as will work for 129)of the tractor not a part number witch I can't get off my starter generator because it's Mia. I,have no I'd tags on the tractor because it was restored and they never got put back on. So I was wondering if there is a difference in them or if they are the same thing. I do see the specs are the same.

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

I was searching for pictures to illustrate what I told you with words. I looked in Yahoo under starter generator. I clicked on images. I selected one. I happened to look at the tag under the picture and it referred to an article in GT talk. It was a very good article. I think you could get there by searching under: Tech Tips/How To, Article: Taking care of your Delco Remy Starter Generator. Once you find it, the one pictured with the aluminum rear bearing plate would look correct, not the one with two ball bearings.

Compare the business ends of these two Delco Remy starter generators. The first is a cow (counter clockwise) rotation starter needed for a cub cadet.IMG_0384.JPG The second is a cow (clockwise) rotation starter used for nearly all other applications where the belt pulley is on the flywheel.IMG_0387.JPG Compare the centerline of the mounting bolts. The third picture is of a generator that has a second ball bearing in a cast iron housing on the rear. Yours originally came with the bronze bushing in an aluminum rear housing.IMG_0385.JPG

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
