Speedo Quit

...when is the last time you lubricated the inside of the cable? If they bind-up, they'll just snap in half! Perhaps your drill is just spinning the 'Free' half...

...you might get the generator that fits the ZF output, and install/wire-in the Electronic Speedo. No more Cable!...

...I see Now that You spun the SPEEDO with the Drill. Don't know if that is repairable...

Thanks,

I spun the ZF end of the cable to see if the needle would move. It's possible the cable is broken somewhere in between. I'll pull the end off the guage and see if it spins at both ends. If it's broken can I get just the insert or do I have to get the whole cable?

...I would look for a 'Speedometer Shop' in My area. They would have every fitting needed to make up a new(Inside)cable. Be sure to take ALL of Your Broken Cable(if this is Your case)into the Shop, so they can Get the Length correct! You would NOT have to remove the Outside 'Sheath'. But check to make sure there are No sharp bends or kinks in the sheath that caused your problem in the first place! Then just lube it up as you slide it in, Fixed! I use 'Teflon Grease', or a very thin Oil. Good-Luck with it!...

Doug,

With the cable disconnected from the speedo head, you should be able to turn the speedo (not the cable) by hand. Give it a "spin" by hand and watch (or have someone else watch) for needle movement. If the needle moves, then the head is probably ok. I forget if it is clockwise or ccw.

Depends entirely on whether the speedo cable broke or its something else thats gone wrong. If the inner cable did break, it could simply have worn through the polyethylene cable liner, which themcatches the inner cable and snaps it. Adding a new inner cable into a worn outer, greased or not, will very likely break the new inner cable too. When I did this many years ago, the new inner cable did not survive a ride around the block. Complete new speedo cable assemblies are now teflon lined and work much more smoothly, likely also living longer.
