Greetings All from a newbie in PA! Was recently given a Lionel #154 loco and 3 passenger cars. It appears that this set was given an amateur restoration some time ago. Looks OK (not as original) but on inspection, the motor needs to be replaced. One broken wheel flange, all bushings badly worn (wheels, armature wobble), armature windings have bare spots, looks like armature laminations make contact with field laminations (bright spots). Motor runs for a few minutes then dies. Seeking a reasonably priced good running 150 series hump back motor. Any suggestions, etc. would be most helpful. Thanks for your indulgence.
