Generator re-build questions

Hey all,

So my '52 f-1's generator is all screwed up... it's charging capabilities are unknown to me as of yet because I disconnected it once it started emitting smoke and smelling like burnt rubber.

1) The truck was converted to 12-volt before I acquired it, but is it possible that my generator is (or WAS) fine, and was overloaded because it is (was) still wound for a 6-volt system?

2) Has anyone here rebuilt one themselves? I'm interested in doing it, but I'm still in the 'research' stages of this little job and don't really know what kind of trouble I'm asking for just yet.

Anyone have any tips...? pointers...?
Should I do it myself or have it done...?

My instincts are telling me to dive and learn something in the process,
... and my brain is telling me I don't know what I'm getting into.
 
Get a generator for a 12 volt Ford, something like off a Y block. Use the case, armature, and rear bearing and put everything else from your 6 volt generator together. Then you have a bone stock looking 12 volt generator and you have learned something.
 
I think your instincts are good Dave. The generator rebuild is fairly straight forward. Nothing very complex about them. Taking it apart is easy, 2 external long bolts. If the windings are fried they will have to be replace with 12V windings. To remove the field coil bolts (bolts that hold windings inside the case) you may need to go to a shop that works on generators if you can't remove them yourself. They have a press- like tool that holds the square driver into the bolt while loosening it. If you've got the time, it would be an rewarding learning experience. I was able to snag a helpful book off of ebay. I have no idea what a shop charges for a rebuild but if cost is a factor you should give it a try. Good luck if you decide to tackle it. The pictures are of a diassembled 1 post genny, yours is probably a 2 post. Just as easy to work on. Dennis/Arkansas

I used to do this back in the day. Make sure your commutator is round and concentric with the armature shaft and that the mica separating the bars is below the commutator surface. Also, make sure the brushes slide nicely in their holders. You might have to position them in the holders with the spring pushing on their sides instead of on their back ends when you assemble. Once it's together, kick the end of the spring onto the back side. Make sure there's no arcing at the brushes when it's on the engine and charging. Got a good 12V regulator? It should charge at about 14.2 volts. Good luck!!
PS: Did it smoke with the engine running or off? If off, it might have come from a stuck closed cutout contact in the regulator! Might do it again if you don't get that squared away.

Not to steal this thread, but I heard places offer kits to convert your sock 6v generator to 12v. Anyone know of a place that sells these?
