Ed - the speedo and odo are 2 different animals, the number wheels have tiny plastic tabs on the sides of the wheels that catch the wheel next to them and pull it along when turning past 0 - after many years if the shaft gets gummy, the force needed to turn the adjacent wheel can be enough to break off one of the tabs, usually toward the right so all the numbers stop turning
