[Healeys] Smittys and Speedo

[Bob Spidell]

I had the exact same problem with my speedo, except it manifested itself with a periodic jump from an otherwise solid indicator. I was able to glue the crack and glued a nylon washer on the outside for reinforcement. Had to file the gears a bit with a jeweler's file to get smooth meshing.

In speedometers that have failed on me, the problem you describe has been 
due to the small 'nylon' or plastic gears that drive the numbers splitting 
on their shafts causing two teeth to have a wider gap between them. The 
driving gear then jams up where split because it can not mesh properly. 
Replacement of the broken gear has solved the problem.
