If you’ve dealt with a failure of the alternator drive coupling on a Continental engine, you now understand the importance of the coupling inspection. Massachusetts-based Approach Aviation initially came out with a tool kit (ADCKIT1) designed for the proper removal, testing and installation of the alternator drive couplings found on Continental IO-520/550 series engines.
Now the company has a new kit—the ADCKIT2—that supports the inspection and installation on a wide variety of Continental engines. This includes the C-75/85/90/115/145, the E-165/185/225, the O-200/300 and the IO-240/360 series engines. It also works with IO-520/550 drive couplings.
