My 78 speedo isnt working, tryed new cable , which didnt help it, the needle bounces about like a mad man, and then sticks, and bounces again, so where can I buy a new speedo or a rebuilt one?

thanks

Willcox or ZipProducts would be my first 2 places to check.

Do you have cruise control. There would be 2 cables to check. If its bouncing around, it sounds like a cable problem.

 

Could the nylon gear in the transmission be stripped? Sounds like a speedo, but I"d take a look. Hook a drill to the speedo cable at the transmission and see if the speed is steady on the dash. Or, just pull out the nylon gear and take a look.

 

If you have cruise, it's probably the lower cable.

 

sorry guys, but ive had a new gearbox installed with new speedo gear and a new single cable bypassing cruise control

 

Then I'd say your original question is valid. Eckler's has an ad for $135 plus parts and shipping for restoration. Seems like a lot of money, haven't seen any listed for sale. Did you try taking yours out and lubing the movement? Don't know if it's possible, but I'd try before I paid that much. Just to be sure it's not in the transmission, I'd still hook a drill to the lower end of the cable if I were testing.

 

On a car with cruise control, you can un-screw the cable between the cruise unit and the speedometer and run it with a drill to see if it works. If the speedometer works, then move to the lower cable and test it in the same manner.

When cruise control transducers lock up, they usually wipe out the lower cable. If you have movement with the upper cable and nothing when you test the lower cable you can remove and install a new cable, but if you do this test it with your fingers before you hook it to the transmission. If the new cable feels the slightest bit hard to turn or if you feel a drag in the cable the cruise transducer is causing your problem and hooking up the cable will only eat up the new cable.

If you test the top cable, the bottom cable and everything appears to work properly, then you can go to the transmission for the problem.

If the transducer is bad, we can rebuild them or you can purchase the non cruise control cable and bypass the cruise control all together.

If the speedometer is bad, we still have the parts in stock to rebuild them.
