alternator questions

[rcbeam]

Luvrbus:  I measured the camshaft pulley on my bus and it is 5".  I can't find a suitable alternator pulley anywhere in town.  I talked with a guy from an alternator supply house on the net today (can't remember the company just now) and he looked it all up for me and said there was no suitable size double pulley that would fit the Bosch T1.  I was trying to make it work in a situation it was not designed for.  It would not put out enough low speed power because of the pulley size.  The big reason was the large shaft.  NOW, if i go to a small shaft alternator he said I had tons of options.  Quite a few manufacturers make 24V, 150A small shaft alternators. 

SO, I'm going to take the used alternator back to the tour bus guy and tell him it just isn't going to work and I'll buy a new small shaft alternator.  I really need this problem to be over so i can get on with other problems.  I've wasted several weeks on this so far.

One thing for sure, I've learned about pulley sizes, ratio's, and today I read about pitch.  Not an expert by any means, but I now know more than I knew there was to know about pulleys.

I appreciate everyone's help.
