Here's a photo showing the two odometers all taken apart. You can see the thin metal divider plates with their little gears. The wheels have a full "ring gear" on one side, and a very short section of teeth between "9" and "0" on the other side. The little gears have "extended" teeth on one side that engage that short section of teeth on the wheel to advance the next wheel one place. It's a very clever design.
