67 GTO Speedo issue

cmunson · 04-20-2008, 10:09 AM

I have a 67 GTO that has a speedo that works but the odometer does not move. Does anyone have any advice on sorting this out? I don't know if there is anyplace out there that repairs them or is getting a replacement the best thing to do? Also wondering if anyone has any clues on how difficult it is to get one out.

Another thing, when my speed changes rapidly the needle gets real jumpy varying about 10 mph up/down/up/down. I am pretty sure this is just the fact that it is old technology but wondering if anyone knew if the reproductions available suffer from this same thing?

The speed juming up and down is more then likely a bad speedo cable. You may be able to lube the inner cable, but most of the time they just need to be replaced.
The odometer not working with the speedo working fine is going to be the speedo head needs to be repaired or replaced.

There is a zeroed out speedo head for sale on ebay now....cables are easy to find. Eric

Thanks for the feedback. That seems to be what I need. Now I need to figure out how difficult it is to get out/in. . . Thoughts on this subject are appreciated. . .

Rukee is right about the gears in the speedo head. (I just went through the same problem with the Vette). The Goat dash is easier to work on, but save your back and pull the driver's seat out before you go under the dash. Use some masking tape and mark all the wires and connectors as you disconnect them; its amazing how fast one can forget!

Yeah I did a speedo cable a while ago in my 67. Defintely easy dash to work on but just take your time a mark everything out. I think you can get the cable from Performance Years or Year One. Not that hard to find.

I know there are about a dozen screws that I found that circle the dash. Are there any other gotchas that you can think of or is it just 'keep removing screws until it frees up'. Good tip about the wires. . . .I missed the eBay auction on the speedo but am wondering if anyone has any clue about how difficult it might be to fix an odometer. I am sure it depends on what is wrong but it seems that there wouldn't be many moving parts. . .

It`s probably one of the tiny gears inside stripped out.
That`s one way to keep the miles low.

If you take your's out of the dash, i am sure that there is a bunch of gouy advertising in Hemming,s that repair speedo/odo's. then you will know that you have a nice refurbished unit......E
