one could be built, or found......... 70+ amps is a lot at 24 volts, it is like having 150 amps at 12 volts, lots of power

which model? 27si, 21si, or 22 si? I am going to stick with the newer units, they are more reliable, and the price is right

I wish i had a dyno for comparison, it does run great, free revving, and charges like crazy.....

post pics man!

post pics when you get it, group brainstorming works great for coming up with inventive mods

A, and C, are the rear mount, and the front mount, the bracket needs clearance between b, and c for the water pump hose...... right under the area marked B is a bolt which is in the way of the tab on the rear of the new alternator, and the bracket would have to be notched to clear the rear...

Here is a pic of the lower block mount for the alternator I have labeled points of interest a,b,c....

you have to re index the rear of the alternator....... the cast iron bracket is in the way, you could remake the whole lower bracket, why i did not do that I have no idea, maybe it is just because i had bar stock....... you will see, take the bracket off of the block and try it in a vise, you...

lemme know if you need any help, info, or parts, i will do what i can, no cost.....

this will work with the 115 dollar alternators which can be rebuilt very cheaply a person could make the spacer, or get one form me, and use a section of flat stock drilled for the arm, and not have a lot of money invested for what is a better, more powerful alternator which can be found or...

Here are some pictures of the whole thing, simple, easy, and rock solid, I used a more expensive alternator than i had to, why? I have no clue, but the unit has the same mounting as the lester number listed above..... simple j-mount unit The unit mounted with the longer of the two brackets...

OK, Mine is up and running, there are some changes........ First the shaft size is wrong, the std deuce alternator has a 5/8 shaft, the alt I used (22SI) has a 7/8, so i bought a pulley...... You MUST use the deuce pulley spacer from the std deuce alternator to get the correct pulley...

that would be a nice group buy for sure........

obsolete parts Cinci Ohio 513-731-4134 I already have a new unit on the way, I will repair this one for a spare

I called them first, they sent me to the place in ohio, the place in Mi near me will sell regulators to me, but want to sell me 30 at a time minimum, I do not get favor with them being a busines either, I was told on this site to get in touch with them, it was mentioned that someone had gotten a...

I found a company that has the regulators, it is called obsolete parts in cinci ohio 175 each too much finding them is not hard, paying for them is

I just ordered a new, non rebuilt 22SI alternator, 24 volt, 70 amp, current production for big trucks, cheap to rebuild, like 40 dollars for all the rebuild parts...... the deuce pulley works on it, it comes with the fan, and is a 1 wire hookup, all you need to run it is to hook the charge wire...

the pulley from the deuce should be a direct bolt in swap..... I will know more today I am digging right now, it will be nice to have a near drop in swap for the guys who want a cheaper alternative than a stock item

do a search, alternators are categorized by a "lester #" do an internet search for "LESTER 7197" it is a GM/Delco 24 volt, 65 amp alternator that has mounting tabs which are extremely close to the original deuce alternator, very minor wire mod, and about 115 dollars should get you one

nope, no good, gotta convert it all for a 12 volt system those alternators appear to be an add on alternator to supply a 3rd stand alone battery for 12 equipment, in addition to the original truck 24 volt system, not as a replacement
