To answer a few questions; I have several Dual Voltage 12/24 alternators on LMTV models. All running with success. Last post to me is a customer with 2500 plus miles on several trips. We follow up with a couple calls to check on them.
Paint is only paint. Anyone and $4 paint can change to the color they like. We however, will add a few color choices recommended.
My shop man said I made a error. We are sending out 110 amps at 27.4 volts and not the 70 amp model in our dual alternator. They are custom wound for us. Our cost is close to the standard 70 amp, so now 145 amps at 14.2 v and 110 amps at 27.4 v... Now to up date the web site. double-alt.com
By having two separate mounted alts your have to find, build, install brackets and change belt sizes to match. Yes it can be done but, it is not easy to build heavy duty and get the belts aligned. 2. The belt needs to circle around more than 90% of the pulley which usually requires a idler pulley. All of this adds to time and money. And finally you still do not have a well engineered True Dual Voltage alternator with controlled air flow, nor can you add a Air Filter.
Let me point out what I have heard and what I have seen in mounting. On the LMTV and MTV the bottom bolt is under size.
It allows the alternator to shake in the mount. The top bolt is about 3/8 inch. It breaks off or the top mount bracket cracks off. We use a 1/2 inch bolt on the bottom and 1/2 inch on the top. Case closed. The Military alt is 53 pounds (100 x 100) Ours is 31 pounds. Helps your back. Please check yours for cracks or broken top bolt and let me know.
Old saying pay now or pay later. Not trying to be a smarta---
Here is a cement truck alternator picture. I took my finger to wipe away the dirt to see the model number.
