I am Lionel O gauge guy. After 40 years I just got back into trains. My wife dragged me to the Grand Strand Model RR club in Myrtle Beach, SC in October 2016. I know only Lionel trains. Not very proficient, but I do get by. Two weeks ago the president of my club hands me a newly acquired donation telling me it has a bind and see if I can get it to run. It's an American Flyer O gauge tin plate engine and tender without any markings, I was told it is a 3162 engine. We have 65 members in the club and no one is familiar with AF so it's basically me and the internet. There is isn't a lot of info on this engine.
After disassembling the unit I found that the drive wheels are rotted and rubbing against the engine frame. I removed the armature and I cleaned and tested it. (I never saw an armature go through the side of an engine) I did find that one of the brush springs consisted of 2 smaller springs to make one and the other spring looked normal. I also found steel rivets with the springs. All the gearing looked good. I didn't want to order parts to rebuild till I was sure the motor would work.
My first problem was trying to get the brushes and springs to stay in place while reassembling the brush plate onto the motor frame. I know I am doing something wrong or there is a secret way to reassemble the motor.
It would be greatly appreciated if someone here could tell me how to get the brushes and the brush plate mounted to the motor.
Thank you,
Bob C
