I can try to get you some I don't have a lift so the pics won't be amazingIf you have any photos, that would be something I'd like to see.
Thanks, Dave
Hello Guest, welcome to the initial stages of our new platform!
You can find some additional information about where we are in the process of migrating the board and setting up our new software here
Thank you for being a part of our community!

just a heads up if you intend on putting a 250amp alternator you are going to need a get a bigger gauge power wire and ground to your battery I learned that lesson the hard way
Eric knows the dirt on them since he helped develop them. I think there was a different in regulator plug on the back between the 140 and the 170's. Mine is also cast DR44 on the front. I believe the ones MM was selling were hopped up 140's. but honestly it's been too damned long. lol
I'd rock a 140 or a 170 on the Dodge anyway, step up from the 116 it has. lol
So yours may be a mystery alternator too.
I think there was a serious lack of solid info when these Mechman were offered. I was told the one I bought was a 140a unit (although I never got any documentation or a part number). It was $300. You were told you have a 170a unit.
I found the below info in a Mechman catalog online. That's my exact alternator (as far as the case anyway). G series 3-phase unit available in 240 or 270 amp.
I asked Mechman and they don't seem to know either. No one knows squat.
I'm not obsessing over it, but just curious. Maybe I'll sell it, but who wants an alternator with so many mysteries.
Dave
Too? There's no mystery, your unit is an AD230. Your unit was custom built for your application, that's why there isn't a lot of information. There was no part number, again, custom built for your application. You got a 170a unit, as tested before shipping.
SO what do you want to know about your alternator Dave?
None of these are "mystery alternators."
The suggestion I have for you to consider is the Gates dual V belts. They sell V belts that are two V belts joined together. There is a measuring tool they use to get the correct spacing. These are used on trucks. I have a 1999 gates catalog that features them. I never tried one because I couldn't find one short enough. I did find the correct spacing that fit the Volvo dual pulley. With the added length of the tensioner there may be one that fits for you.
For a while several companies, including Gates, were selling matched pairs as well. I have to go that route on the Dodge, seen some large variances on the same part number, but the MP seem pretty damned close.
The Gates website doesn't talk about a Dual V-Belt, but they show "PU V-Belts" (pic below). Page here: https://www.gates.com/us/en/power-transmission/v-belts/pu-v-belts/c/114
Maybe the PU belt is their new name for it. As far as length, they begin at 1000 mm, so it could fit my application (I'm using 1060 mm now). The Gates site doesn't seem to have the width specs you have in your catalog.
I do see some places offering Gates "Dual V-Belts" for sale, but so far none of those list any width specs. I like the style, but I have some doubts about it fitting our pulleys, since our pulleys have a fairly wide wall between the belts.
There are some places offering things like Gates Powerband Joined Belts and Polyflex JB belts, which are the same type of belt. But again there is little info on the width specs. http://www.biedlers-belts.com/powerband-joined-belts.html/ And at about $70 I don't want to buy something just to see it up close.
Here's a 300-plus page Gates PDF catalog I found dated 2010: https://www.bearingsandindustrialsupply.com/pdf/heavy_duty_vbelt_drive.pdf It's extensive and it probably has the info you found. I'll look at it closer later.

Few things:
Those belts will require machining on the pulleys. It would be easier to just move the damn alternator to the other side.
If you really want to run that, which will actually have less surface area than the stock arrangement, go buy a pulley for that style of belt and machine your stock pulleys to match.
If you upgrade to the BMW electric power steering pump, youll need to upgrade to a 500 amp alternator.
Alternatively:
Just get a proper sized fan, one of these https://derale.com/product-footer/electric-fans/fan-controllers/pwm-controller/pwm-fan-controller-push-in-probe-detail and a normal 100-140 amp alternator and move on with life
Strange Dave. I've got the 940 fan, no issues running the AC in 110* ambient in traffic, other than the AC doesn't work as well (converted system BS). Never had an issue with overheating and I'm only running the fan on low. Only overheating I had was a 2 mile long grade plus several high throttle pulls while tuning, with the AC on due to 102* ambients. Turned the AC off, heat on, fan bumped to high and it was down to normal in about 45 seconds.
