Overhauled alternator drive couplings for the gear driven TCM alternators.
Additional core charge added to purchase at time of checkout
Living in VA, I received it in one day from Aero Performance (warehouse) in Pennsylvania. Good quality, worked fine but the core charge too large, $300.
The drive coupling is supposed to be checked every 500 hours per service bulletin, but Im sure most people dont. Mine started slipping, then gave up all together. You could turn the old coupling by hand, the service bulletin tells you how to check it.. I havent received my core credit yet, they must really want them back since its $300.00.
Im waiting for the address when send the core.
The drive coupling I received would not pass the torque check. It started slipping at 116 in lbs vs 180. I had to return it and get one from a different vendor in Montrose CO. This isnt the first time Ive had problems with something from Quality Aircraft Accessories.
