The generator isn't under the hood on a Super A. Frankly, I don't think there's an alternator small enough to fit up in there even if you wanted to hide it.

Well I can tell you this: I replaced the generator on my 450 with an alternator from an early 1970's Chevy, and it works great, but it really doesn't fit well under the sheet metal....so you probably would want one that is smaller than what I've got. It works great, it's just not pretty!

I'm sure someone here will have it - I got a Hitachi number from some folks on here. It works really well on the M and I have one on my A also. With the M the installation was easy. With the A I had to weld up a mounting bracket. Still works really nice there.

If no one comes up with that Hitachi number I can go out to the shed and get it. I've been meaning to find a reason out of this house anyway.

Just get your gen serviced and good cables and also the starter and you wont need to worry about Alt mountings or maybe you will like starter problems you can have going to 12v . SA sure doesent need 12v.

I used an alternator form a 1980 Chev pick up no power any thing no AC on my A and it fit just fine but then the gen or alternator on the A, B, Super A sit below the hood not under it. Once the weather gets a bit nicer I will be doing a 12 volt conversion on a friends Super A

The Hitachi fits under the hood nicely on the H, I think the super A is outside. Don't worry about converting it to 12V if you want to. It is very convenient having all equipment at the same voltage.

The Hitachi alternator number is 14231 and was orginally used on the Nissan 1978-1980 model 620 and 720 pick-ups with the 2 liter engine. It fits nicely on a Farmall H but your application is below the hood so other alternators will work fine for you as noted earlier. Remember the Hitachi is in metrics so the fasteners won't be compatible with both the tractor and alternator. You will probably have to drill some of the mounting holes larger for bolts that fit your tractor. You will need a metric bolt for the adjustment strap as that hole will be threaded in the alternator. Good luck with your conversion, Hal.

Yup, Hitachi 14231. Got mine from Rockauto.com. Converted my SMTA. Works great. Nice to not have to worry about the peculiarities of the old generator system. Gonna switch all my tractors, keep one spare alternator on the shelf, just in case.

If done right a Delco 10si will fit under the hood of an H or M I know I have done so more then once. Ya the Hitachi being smaller give more room but the other fits also

I did use the Hitachi on my Super H.

On my Super C's I use Delco alternators as you can't get them under the hood of a SC/SA anyway.

I changed my C and Super C to a six volt alternator years ago. They are just Delco alternators with a six volt regulator. The alternator hangs out from the block a lot more than the original generator. The shop that built the alternators told me that they could get one with a longer shaft, that would tuck in behind the water pump boss and fit more like the generator did. That was another forty bucks i didn't have at the time. I also made a cover to guard the belt, and protect the alternator from the weather.

Even the Hitachi 14231 will NOT fit under the hood of a Super A. It is too large.
