I had the alternator quit on my IV-P at 30 hours. There are no gears
involved precisely to avoid the problems
you mentioned. Instead there is a nonmetallic coupling that is very
expensive to replace.
Fortunately, the warrenty covered it. I fly with a 20 amp backup
alternator, just in case..
BTW, When the bearing inside your Slick mag freezes, you will
experience the same problems you mentioned.
(dont ask me how I know). BUMMER

Hi All,
A buddy of mine recently had some bad luck. He was flying his Cessna 310
back from Calgary and enroute to Thunder Bay, the alternator light went on
just before landing. He landed in Thunder Bay, where he was overnighting,
and contacted his mechanic who told him that it was probably a just a lose
wire and that he had a backup alternator that could get him home (a few hour
vfr flight) the next day. So the next day he starts his plane, does a run
up. Then the RPM starts dropping, then MP drops and all of a sudden the
engine stops. Everything seized up and nothing (the starter or hand) could
move the prop. Anyhow, what the suspect happened is that a bearing or
something got chewed up and the metal all went throughout the engine, turbo
chargers, etc (everywhere the oil went). Long story short, its going to be
about $75,000 by the time he gets out of there flying again (he will
probably get $17k for his core though).... This got my thinking as our
alternators on our IVP planes are at the front with no belts and I don't
want to have the same thing happen --- I have an ALX 9524R alternator ---
what has been the experience of our fleet? Do you guys do preventative
maintenance or do you have any suggestions for me? Or did my buddy just
have some bad luck and I'm thinking too much?!
Regards,
Dico
