| Subject: | Alternator longevity? |
We have the Motorola 60A alternator S/H offered as an option 20 years ago.
Comes with larger pulley to reduce rotational speed. Still, I have to overhaul
it every 400 to 500 hours.
Have had to replace one case half (fretting), always bearings (upgraded to HD
bearings, but not much improvement), sometimes diodes, and this last time,
the stator failed from vibration. Just about every part has failed at 2600 hrs
except the rotor. Have a blast tube blowing on the alternator for some cooling.
Am wondering what kind of time between overhaul you all are seeing on
alternators? What lasts the longest? I'd switch to the Nippon everyone seems to
use,
but we have an old narrow deck engine, and I have a funky, custom bracket that
I'd rather not re-engineer.
Thanks,
Mike Palmer <><

Bruce,
I have a fixed gear tricycle GII. Upon crossing a cross runway intersection noted
for its bump, the front wheel pant came loose [my bad - didn't have it tightened
like I thought I did] and chewed up the fiberglass and foam fairing around
the front strut near the wheel pivot point.
Question: Is there a quick way to purchase a new fairing, or should I just repair
the damage?
I already purchased a new pant from Glasair.
Thanks,
John Markey

Hi Mike, you probably aren't going to have much luck
with your question. Very few people on this list have
enough hours on their aircrft to wear one out. ;<)

It shouldn't be that difficult to fix the old one. Or buy another from
Glasair Aviation.
