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.

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.

Very few people on this list have enough hours on their aircrft to wear one out. ;<) --- MPPalmer@aol.com wrote: > 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.
