Mine went out last week - first the odometer could not be reset for a bit, then the speedo quit. Took it out and and inspected everything, the Smith's speedo mechanism locked up and took out the nylon gear in the right angle reverse adapter. I called around and had no luck in finding a repair source, several people told me to just replace it so I did. Got another one from Hillbank and is working fine now. If you find a source that repairs these I'd like to know who/where and any cost estimate. Thanks and good luck
