Internal odo failure... the speedo and the odo work both separatelly but of course reaction on the same main worm.

The main worn is attached to the driveshaft which makes work the axle to move the magnet assembly.

Then outer gears are geared to this driveshaft worm to make the speedo to spin. Usually two other worms to reach the odo gear.
