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 alignment
A large washer could be made to work, or i can make you one if you do not have one
the front mounts are fine, the rear mount is off, the j-mount alternators have a 4 inch spacing between the front and rear mount
The rear housing of the alternator is in a bad spot, you must rotate it counter clockwise to clear the std deuce block mount with the std deuce diameter pulley
If you have a pulley which is aftermarket and smaller than the std unit you will need to completely filp the rear housing of the new alternator, yup, a 180 degree spin
No wiring harness mods are needed
I can bore your pulley for free, you pay shipping, boring the pulley would be the best and cheapest route to go, I will experiment on Mine first
Mine charges at 27.5 volts and puts out 75 amps
I made 2 aluminum brackets from round stock to secure the rear of the alternator and get rid of the flexing action........
I will post pics later today
I can make brackets for you if you need them, there is an arm that will be longer, or shorter depending upon the degrees of rotation/pulley used
the bushing in the rear of the new alternator has to be removed to use my brackets, nice and solid
need any more help call me 734-682-5107, and i can get the alternators at cost
