I recently bought a lot of junkers, Tyco- Mantua diesels. i did manage to get the engines running, they were rusted up pretty bad, however, they run erratically not smooth. There are two brass bands that cover the bearings, they are riveted. I need to pull the armature out to clean the inside, is ther a way to do this ? I'm afraid that if I pull the rivets I'll never find anymore. And finally, is this old engine worth the effort can I use the body shell and re power with a newer motor. Thanks for any advice.

I don't think those brass straps are held down by separate rivets. They are usually pins that are part of the white metal truck casting that are peened over the brass. I don't recommend removing the armature anyway, since you'll lose a majority of the magnetism. You can use a steel keeper on top of the magnet to prevent this, but it's not always 100% effective.
It's better to soak the truck/motor assy. in 90% alcohol for a while, then scrub the old grease and dirt out with an old toothbrush, being sure to clean any gunk from the gaps between the brass plates of the commutator. You can also blast it out with some plastic safe contact cleaner that is available at Shadio Rack.
If the armature and pole pieces are really badly rusted, Liquid Wrench may loosen it up, but remove the brushes beforehand. Soak the motor in alcohol afterwards to remove the oil.
Relube and reassemble. They're very simple, and should run better afterward.

Thank you for the recognition, I flew the F105 Thunderchief (AKA) the "WILD WEASEL" My job was to go in front of the B-52"s over Hanoi and take out as many Sam Sites (surface to air missles) as I could, setting myself up as a target, once they turned their radar on (fan song) God damn it I had them, due to a new sys that we had at that time called an ECM ( electronic counter measures). Thirty five years later I am finally getting the credit that I earned, when I finally came home I was cursed and spit on litterally at the airport. Since you are interested I'll share a little about the aircraft. I had a bomb bay, the only fighter that had nuclear capability, when my ship was designed it was intended to deliver an A bomb to Moscow only on a one way trip. Thank GOD it never came to that. Now I could fly 2000 mi without refueling at speeds up to1,300 mph(2.5 Mach) Any other questions, please feel free to cotact me at thaughawout@yahoo.com Thanks for your interest. Thunder55
