Our hotrod season is over for the year, so I pulled the '36 into the shop. Early in the summer the speedometer quit working so I started taking it apart to diagnose the problem. Probably an broken speedo cable and possible wrecked housing. I unhooked the top end and turned the speedometer head by hand and it worked nicely, good. The top end of the cable felt alright to me, Hmmm, [first pic]. I undid the bottom end of the cable, and it felt good too, Oh, Oh, [pic two]. Once I pulled out the cable and checked it I found it , as good as gold. Then I pulled out the drive mechanism and tested it, nothing the matter, OH, Oh. So I reached in through the speedo drive hole in the extension housing with one finger and tried to turn the plastic gear on the output shaft. This was really hard to do and also very hard to determine whether your finger is slipping on the oily plastic spiral gear, or your finger is actually turning the gear on the output shaft. I guessed the latter. Now I have to take the extension housing off the main case and move the plastic gear back and check the clip that holds it in place. Pic three is all of the stuff taken off to facilitate the removal of the extension housing.
