?The motor you're looking for is very common and used in most Mantua Tyco steam locos. from 0-4-0's to decapods and includes old time 4-6-0's and 4-8-0's. For quite a while both the locos you mentioned used the same motor. Only older 0-6-0's had a slightly different frame, and that's the real old ones. I am surprised they both went bad and you need replacements for both. If you built a kit you know about how to align the gears so they don't lock up or wear out to quickly. You should also know about keeping the electrical pick-up surfaces clean and oiled. That includes the motor shaft and bearings. Being as you know all this stuff you should be able to get at least one of you motors turning.? You should say where your from. Maybe someone close to you has what you're looking for.
