Hi..I have a 1864 and it too had tons of play in the steering. I found the adjusting screw was missing it's jam nut and had backed way out. In the diagram in the above reply I see the jam nut but the screw is out of the picture..Find yours,loosen the jam nut and adjust screw in and turn wheel till it gets a added drag in it and little or no play..1-2 inches in the wheel and tighten jam nut.Don't /forums/images/graemlins/smile.gif forget to grease the box. there's a grease fitting on it.
