I have a 2 6 0 Prairie locomotive that wobbles. I had to tear it down to clean all the smoke oil that was in it and replace the copper wheel contacts as it was corroded. My question is, is there a specific line up of the wheels upon reassembly?
I learned the hard way, when you take something apart, photograph every step of the way down. And put every screw back into where it goes, but without whatever it was holding together, of course.
