Feeling pretty good about the possibilities with theses CD ROM drives, I dove right into remotoring this switcher. It required removing the armature, rear bearing and brush plate and field magnet. On the opposite side, the other bearing was removed then opened up a bit for the new pinion gear. Then it was simply a matter of lining the gears up and securing the motor with Gorilla Glue. The new gear itself came from the scrap box and was from an old toy.
---Something to note: The motors and drives sometimes need a bit of experimenting to orient the polarity properly. In the case of the switcher, the positive side of the motor lead went to the negative side of the model so that it would go in the same direction as the other models when the power pack was set to "Forward".
This remotor and the second TYCO 2-8-0 drive in action...note the flywheel action of the TYCO drive, something most of the salvaged motors have but does not always come through when finally assembled...
