Check where the speedo cable connects with the driveshaft. I had the same problem, the little piece that went from the shfat to the speedo cable sheared off do to a driveshaft bearing failure. Hope this helps. Darren
I have heard that if your speedo stops working due to that key being broke, you have a real short time before that bearing goes out completely. On my Powder Special I actually had the outer race of the bearing broke w/o breaking the key.
I had indication that the bearing was bad besides I heard a weird clicking noise at certain times. Dumped a bunch of grease into that bearing and the noise went away. Tore it down and found that.
in some cases its neither the cable or the bearing going. it could be just as simple as cleaning out the housing that holds the pin in place. i would try cleaning this out before you do anything. once you do this make sure everything spins freely, and if it still breaks or doesn't work after that, you could be looking at a new cable or changing your drive bearing. good luck, keep us posted
