If Scott greases and lubes everything, and she still screams, he can swap out the 550 motor for a 555, it won’t cure it, but it may make it a lot more tolerable,…..auction sites sell them for small money, and that’s a direct bolt on swap….

I keep a couple of the Mabuchi 550 motors on hand, they're cheap and I see a surprising number of Weaver and Williams steam with defective motors. If free-running they draw more than around 2x what the free-running 550 draws, I swap them out. I've found motors that draw several amps free-running, I expect more like 200-300 milliamps.
