Dear Group,

I have read many old threads dealing with using auto alternators on
certificated engines but have been unlucky in finding specifically what I am
looking for regarding an answer to my question. So help me please or send
me in the proper direction to find help. I have an O-320-E2D for my Hatz
biplane and wanted to put an automotive style alternator on it as right now
there is no alternator or mounting hardware. How do I go about getting a
matching set of mounting hardware that will adapt an auto alternator to the
O-320? Is there an after market manufacturer of such a conversion? I can't
see forking out the dough for a whole new set of Lycoming mounting hardware
and a new alternator if I can get good serviceability with the automotive
setup. Saving some money and some weight would be a win win. OK let me
know what you think. I'm sure my newbieness is showing through loud and
clear but I have to start somewhere.

Go to the airport and look at the Cessna 172 alternator setup. You
could bash up a bracket like it out of 1/8" steel plate to mount the
alternator to the crankcase. The adjustment arm could come off an
automobile at the junkyard.
A mid-70s 172 is a good one to examine. You could use a flashlight
and a mirror to see the bracketry without even taking the cowl off.
