Info needed for alternator size

Postby staninlowerAL » Sat Dec 26, 2020 9:35 pm

I need the info on a one wire alternator that is max 4 inches diameter and about 5 inches long max. Most of the info that I have found does not give the physical size. Any direction where to find one is appreciated. Stan

A little more searching and I found the Mini Denso 4 in x 4.5 in. This might work.

The Mini Denso is an excellent choice. It's small size, modest amperage output and low price tick all the boxes for me. There were some smaller alternators used on the compact diesels but they are not very reasonably priced and some require a separate regulator. I assume this would not be for a Cub installation?

Delco 10SI clone, single wire, fits under the Cub's hood. Inexpensive.

Have several installed on tractors. No diode needed.
I have an excuse. CRS.

That's correct Gary, it's a YM1500 and the available space is about the size if a man's fist. Thanks for all the responses, I think I've about got a plan in place to make the mini denso work which retains the dynamo housing/fan shaft for cooling but eliminates the dynamo internal coils/components and rectifier for cost reduction and more reliable parts. Replacing the dynamo and rectifier would be about $350 parts, no labor. Added to that is another $300 to replace the radiator and fan which was destroyed when the dynamo failed and came apart. :shock: :roll: I'm sure you can see what's driving this repair! :)

Sure do, Stan! My oldest Kubota has that setup. Lots of years and no problem with it, but it's there swimming in my brain. My others have water pumps and stand alone alternators. If I had your failure, I'd do exactly as you're hoping to do.

Re: Info needed for alternator size

Glad to know that my idea seems to make sense. I got this tractor when the dynamo had failed and damaged the radiator but was able to repair it with minimum effort and expense. I hope to avoid a 3rd time by changing the setup since the dynamo seems to be not repairable anyway and replacement is around $200. I'll let you know how it works out. BTW, there is a water pump conversion that is available using parts from another Yanmar tractor. It's rather pricey, in the range of $400. If you're interested, google the topic. It's offered by HOYE.
EDIT: Reviewed your profile and saw KUBOTA, not sure about the water pump conversion. I've only looked at YANMAR. Sorry!! :oops:

Mine could be converted, using later parts for the same D850 engine model but a lot has to be changed. It works just fine, as is but if I had a failure, I would certainly look for other ideas.

Agreed, the one I decided to purchase was in the $40 range, including shipping.

This might be a silly question, but if you want a alternator, then why not use the same model that IH used on the late model Cubs?

I dont know the model, but it looks like a GM Delco!
