Before i pull the top brush plate off, I'd like to get some opinions. Apparently there is a worm gear at the lower end of the armature that should get some lubrication. I noticed, in the K-Line Lionel book on the repair of Lionel Trains, that there is a ball bearing in there. Something to watch for when I pull the armature out. Are there any other surprises or suggestions to getting lubrication to the worm gear ?
