          The next step is to disassemble the “guts” of the locomotive.
        
        
          Here is where you will really appreciate the details on my video
        
        
          (see photo 11).
        
        
          Corral the parts in a box or something that can be covered,
        
        
          especially if you are sending the frame off to be milled and
        
        
          won’t be reassembling the loco in a few hours.
        
        
          Remove the copper pick-up strips and the headlight board.
        
        
          They will not be used in the final loco assembly.
        
        
          Remove the screws and nuts.
        
        
          Split the frame slightly and mark the motor as explained in
        
        
          section 2.1
        
        
          Set the trucks aside. Some folks like to mark front and rear
        
        
          trucks for reassembly in the same location. I haven’t
        
        
          seen much variation in these locos; so I don’t worry about it,
        
        
          at least with this model.
        
        
          Remove and store the pieces of the drive train – don’t over
        
        
          look or lose the adapter bushings inside the flywheels.
        
        
          Remove the insulating bushings from the frame halves.
        
        
          Remove the (copper) bearing retainer clips from the right
        
        
          frame half.
        
        
          You should now have two pieces of gray metal (the frame
        
        
          halves) with nothing on them. Now is a good time to use some
        
        
          denatured alcohol and a stiff brush and some Q-tip(s) to clean
        
        
          the frame halves of built-up lubricants and dirt.
        
        
          The frame halves are ready to be machined.
