 This happens frequently. All the removable gears on both ends show no obvious signs of wear, and the teeth are all in good shape. For additional troubleshooting,​ the next thing to do is (with the green cap end still opened up) put a shaft with a wheel on it into the motor and turn the wheel by hand and see what the green-cap-end gears are doing. Do they turn evenly and consistently or do they wobble? Do they stay connected to the teeny gear that's being driven by the actual DC motor, or do they move together and apart as the wheel is turned (indicating a shaft mis-alignment)?​ (This process requires a few people to hold the various parts in place and turn the wheel.) This happens frequently.

-And sometimes it's never clear exactly where the problem is, but when that wheel is cranked, the motor still makes that clicking sound. At this point, one may conclude that (a) there is indeed something broken, ​(b) its exact location is not known, and (c) in the end it doesn'​t matter, because the motor is a goner.+And sometimes it's never clear exactly where the problem is, but when that wheel is cranked, the motor still makes that clicking sound.
