QUOTE: Originally posted by webrer i bought a Brass alco SD40 a few months ago, but when i ran it. I found that it was extremly slow and loud. i opened it up and found that the motor was an open frame motor that powers a set tower drives. I lubed it and tried to give it some tlc, but still sounded the same. Has anyone else tried to repower these locomotives? I would like to upgrade it with a better drive system, (replaceing the tower drives and motor) Any ideas how i could do this?
