The eccentric arm on the fireman's side got out of sync and tangled with the rest of the gear. The unit is quite new and well lubricated. How can I avoid a recurrence? I sent it in, and Bachmann fixed it for me but I do not want it to happen again.

I need to remotor my first-run Lifelike Mallet. Help, please. Love this engine, but motor seized up.

Can you change brushes in a small motor? How, if so.
