Unfortunately Northern Tool hasn't carried that gen head for a few years.
Yes, the Northern Tool gen head does fit on the Yanmar in the 831A. I have one on an 831 in my garage. Pic below.
The equivalent gen head can be purchased from Mecc Alt. I've bought a few of them from them the last couple of years to do conversions.

FYI - I produce conversions kits to do the swap which includes a custom governor controller to maintain 60 Hz, current sensors for overload protection and a transformer assembly to restore battery charger operation and all needed hardware.

I suspect shipping the gen head to PR by MeccAlte could be expensive.
Here is the contact info to get a price quote and a picture of the packing list with the specific gen head to order.

Kurt: I just purchased a governor control and Fault Module from you. I would also like to purchase one of the conversion kits for future use. What is the best way to contact you? On this forum, email or some other method? Thanks - Dave

The Main Gen swap looks great. Hope it works out for you well. The A8 and governor control set up on these was an issue from the start. I have in black and white but you folks don't need that stuff. The A8 had issues with moisture, input wiring, and internal issues. 4 phases and a battery charging winding in the main gen at 274VAC no load and this was the answer, the A8 and A9. The A9 was OK, but not ready for GIs and their charging the vehicle batteries with it, or forgetting and hitting the vehicle starter. Thing runs at 2 speeds. No load and full load. This was hard for folks to understand, and then the new style valve cover led to more. Please do not use it. Use a funnel and the side port for the oil. I got introduced to the new valve cover in 2008 at Mosul. The Soldier said it seemed like the right thing to do as he actually filled the crank case all the way to the oil fill port on the valve cover top. Then he hit the starter. Hydro lock did the rest. Can't count the number of calls of It won't stop. Units always wanted to get 5KW from a 3 KW set. This also did not help the A8s. They are 3KW at best. You run it more than that , borrowed time. I made a drop box system for a Platoon SGT where he ran these out to his platoon of tracks so his soldiers could charge their tooth brushes, game boys, and laptops. This worked great and it spread and each Platoon SGT in his Brigade had a 3KW in the back on Log runs with fuel and chow. GIs loved it and the gens ran great. Still lost a couple as cables were run over by tracks.

We asked units to run them on a pallet. keeps dirt out better as there is a A8 Cooling fan on the bottom sucking moisture and dirt right up into the A8. Really helps. The coating inside seemed to be busted from the factory. In 2010 they started a new coating and it actually helped a little. You got 2 field problems instead of the usual 1. Don't laugh this was real. The governor setting was touchy at best. What I put out is what we got from factory folks. Touchy at best. The rep even had issues on one he was using to show us. It stopped if you got the bail distance close to correct, but you always had the ones that fluctuated and there was not much to get them to stop. Worked a lot of these, and each one runs a little different. The exhaust had bolts break and the things caught fire. Changed the bolts and this helped, till the welds broke. Then came systems out that needed to run 24/7 365 and they wanted to use these. OK, start the lawn mower, and start cutting, 24/7 365 and see how long it goes. This finally got MEP to think about it. I had a bad name for a while, but they conceded. Had a cannon they wanted the 501 to keep batteries charged on it and run 24/7 365 and this was also not a good idea at another site. They had a slave cable and a 5KW so guess what, all got better. Some star thanked me from the states, but I was knee deep in other issues and had no time for such frills. I am a bad source as I got the idea if you wanted small, run a lot, go buy a Honda and save money. I was not the only one thinking this. Please excuse me on this, it is just too many issues on little ones eating the time needed to fix big ones that ran things that saved body bags.

I looked at my MEP831A to see if it was an 8 or a 9.....I didn't see anything that gave me that information.....my was built in 2009.

What am I looking for to determine if my unit is an 8 or a 9?
