I was gifted a Lionel 313 Bascule Bridge for my birthday. I cleaned it up and straightened it out.  The motor works fine. I am having trouble getting the mechanical linkages from the 3rd reduction gear shaft to the bridge axel and to the far tower cam.  I also do not have the spring tension right.  I am looking for someone who knows the correct orientation of the cams and axel tabs or has a picture of them in the proper positions. It is harder than it looks.
