Not sure if this is the correct forum - but here goes. I just acquired a 'lot' of Futaba 3004's and 148s. They all seem to work fine, no travel issues, but I'd like to visually inspect the interanls for any broken / damaged gears, etc.

Can I just remove the screws and take the top off? OR are there issues with doing that.....almost like taking an old spring wound watch apart....BOING!! There go gears and springs flying all over the place...ouch....My eye.
