Default Speedometer question

There has never been a cable hooked up to my speedometer. I hooked up a cable to the spedo and tried to turn it by hand. It did not seem to want to turn. Should it? Or does it take more that my fingers to turn? Should I just hook it to the trans and see if it works? The odometer is stopped on a nice round number. So I guess they disconnected it and that it did not happen to break on such a round number. Thanks

The "nice round number" makes me suspect the previous owner was playing "roll-over" with your odometre to reduce the mileage. If done incorrectly, it could seize up and stop your cable.

Mac may be right.

Also, I don't think you could spin it enough by hand to make it register.

Roger that, Bld, I think you are at least looking at having it cleaned and inspected at a speedometer shop. I am afraid that if you try to force it by connecting it up, you are going to do damage that will cost you more to repair, or you are going to break a cable. If the speedometer doesn't turn, then the cable, which is essentially a long, tight coil spring is going to wind up until it breaks.

Had a similar problem on my 66. When I tried to install a new speedometer cable( old one was broken when I bought the car), the new cable broke. When I took out the speedometer and took it apart I could tell that the gears were frozen. I sent my to Corvette Clocks byRoger in Jackson, Tenn. They restored it and it came back looking like new.

Ok Thanks to all who responed! It is stopped on 40,000 To me that is a "nice round number" :lol: I don't think it broke on that number. I have had it almost 17 years with no speedometer. I am gettting better about finishing up details. Like I said I could not grip the cable and turn it with my hand or get it to turn with pliers. So is the concensus to 1) not hook it up with out removal and inspection? Are you saying just this much time and not being used it will destroy itself if I do hook it up. Or will it just free up? Sorry I had not checked the thread in some time work :rolleyes:

In my opinion, no good thing can happen from connecting the cable. I don't know that you will further damage the speedometer, but speedometers are reliable, fairly precision instruments requiring virtually no load to turn. If you cannot turn the speedometer cable freely with your fingers, you have a problem inside the speedometer, and it is unlikely that it is just "jammed" and subject to repair by "cranking it up" some more. Speedometer cables are really not expected to take any load, so if you have more resistance than the cable can take, the cable just winds up and breaks.

It would be better to have the speedometer checked out by a speedometer shop first, rather than just connect it up and hope that it will heal itself. If the speeometer just needs cleaning, you may get by with little expense. If someone has melted the guts by running it backwards at 4000 mph, then you can connect all the cables you want, and it isn't going to change the outcome.

You surely have a speedometer shop in your locale; check the yellow pages. It will be cheaper than sending it off to a specialist. Your old speedometer is probably due for a cleaning anyway after all these years. :D

When I bought my '58 the previous owner said that the speedometer was working but just quite working a couple of months ago.

1. Disconnected the cable from the speedometer and check gear in transmission -- OK No Problem

2. Turned cable by hand and turn freely but could need little lube.

3. Disconnect cable for speedo turn cable and determinded that it was not broke.

4. Reinstalled cable several times making sure it was seating properly and still nothing.

5. Pulled Speedometer and found no guts -- think I found the problem. :eek:

6. Talk to previous owner and he said that was impossible since it was working. Where do you suppose the guts to my speedometer went? :confused:

7. Found complete new speedometer on Ebay and purchased a new cable. I have it installed now but haven't got the gear reinstalled in the transmission. Only took a year!!!

End of Story!!!

No question in my mind- alien abduction. 58 was a very popular year with the Grays; it turns out they like the extra chrome. No doubt some well intentioned BEM (bug eyed monster) 'borrowed' the guts to your speedo so he could replicate it aboard his ship but then he was spotted by some frat boys out drinking in the boonies so the BEM had to depart before he could return your parts.

If only we could get greater access to the alien's technology instead of having it being restricted to so few people. What? You mean you don't believe the BEMs have replicated Vettes? Count the low mileage, highly optioned 67 BB 435s and get back to me, okay?
