This is really helpful. We have several units that aren't functioning. On the only one I've pulled apart so far, the threaded part of the gear was stripped. I called our Trane dealer a couple of weeks ago asking for a kit just like this but they say they are no longer available. I found the motor and drive gears alcomech mentioned but I'd like to get a few complete kits in. Do you have a source for these kits?
There isn't a kit per say. I always order the backplate assembly, actuator motor, and capacitor. The part numbers will vary with box size.
