Thanks Terry and bapguy! The set from Amazon is a more than I need, but the Athearn springs look like what I need. I appreciate it!

Thanks, Len! I'll try that but I think those springs are too small. I'll let you know.

I know this is a long shot because pancake motors haven't been around since the 80's, but I am trying to find the tiny springs that apply pressure to the motor brushes. Anyone have any ideas?
