12V Conversion Alternator Belt

My question is, what should the belt size be? Should I put the alternator where I want it and measure the distance around the pulleys? Is the length standard enough that you guys can make a recommendation?

You guys give great info. I love reading through problems and your responses. It would be great to see you collaberate on a 9/2/8N tips and tricks manual.

Thanks,

Dave. :-)

All I can say is, duh, why did not I think of that!

How could I ever live without you guys? Also, how can I tell when the front bushing needs to be replaced?

Thanks,

Dave. :-)

While redoing my alternator last November, I hit upon a solution by accident which may help. I anchored the alternator in the same mounting holes as the original generator. After I did, little did I know that the new alternator was a little over a belt width shy of aligned. I tried to remove the pully from the old alternator, and managed to break a big chip out of it. Saturday afternoon, parts stores closed..... you know the story! Well, I had an old alternator a guy had given me for a core refund that had a double sheave on it. In desperation, I tried it, and, lo and behold! it was the PERFECT width, if I used the outer sheave. The alternator sits back a little further because of this, and I have no problems such as you describe. Hope this helps. Good luck!

As far as belt size, I did mine by trial and error.

Possibly contact John.COLO who makes up brackets and might know what belt fits (although this is dependent on the pulley size.)
