Default Who pays follow-up

Dave,
My bonanza has a 70A alternator that is belt driven off the back of the
engine, IO470.

Toyota already offers what Detroit is promising - actually I think Ford
does too. My Camry Hybrid has electric power steering, electric power
assist brakes, electric AC, etc. The engine only runs when it needs
to. Very clever car. I've put about 1400 miles on it and so far so good.

If it's easy to get at, and all other things being equal, can you swap
alternators with a known good one (meaning pulley)?


I've wondered about the whole idea of belt drive; given that you must pull
the prop to change same.

I've pondered a smooth pulley in place of the existing one, then a
rubber drive wheel on the alternator/vacuum pump etc.... I suppose
icing may be an issue, as well as having to locate the accessories
directly adjacent to the engine axis.

The other way would be driving the belt with the back of engine
pulley, but that has other issues...

BTW, Real Soon Now, Detroit is promising everything will be
electric-driven; water pump, power steering, air conditioning, you
name it. They'll build a starter/ alternator into the flywheel/bell
housing area. The engine won't idle; it will stop at red lights
and restart when you hit the gas...
