Noisy alternator belt - the saga continues ****
Ok I need help!!
RV10 with PP alternator. I pulled the prop to replace the front seal. I decided not to replace the alternator belt while the prop was off because it had been changed about 50 hours before. Re-installed everything ran up the engine all was well. Test flew the plane and while taxing back to hanger belt started making noise at lower RPM's but not at idle. Checked alignment and that was not the problem, tried belt dressing, that didn't help. Bummer!!! Pulled prop back off cleaned belt dressing off of everything, checked the alternator pully and flywheel for any signs of problems and found none, put a new belt on and the prop. Ran up the engine and the darned belt started making noise at lower RPM's but not at idle again. Anybody have this problem before or have some good ideas because I'm tapped out and bummed.
