saving my speed o

I took apart the speed o on my 47 coupe all the guts look pretty clean, but where the speed o cable hooks into the back is pretty crusty. Do you guys think it's fixable?

It shouldn't be a problem. Clean it up and lube the shaft and gears with light oil. If it isn't stuck it should be okay.
 
Also check the turtle gear at the transmission... when I had my trans rebuilt last Nov, I replaced the cable & turtle gear (worn,chipped)... It works perfect now! .... :cool:

I put a lil PB blaster on it last night. Is there a way to bench test it?

I don't even have the speed o cable anyone not sure how long it's been sitting out in the elements before I bought the car
 
that sounds easy enough, I might just use a ratchet and work it loose first. Was the speed-o cable threaded into the assy?

No cable connected.You will see the square opening for the cable end.First carefully try to free it up with a small flat screwdriver tip using some 3 in 1 oil or equivalent.I do it on the bench
 
Here's some better pics

I use Gumout carb. cleaner with the straw in the nozzle and spray into the square end to clean out what appears to be grease and crud from the pictures, also make sure the spring is not broken on the shaft where the speedo needle attaches, picture shows something around that area. But that may not free up the movement, the inner gears may need also cleaned and lubricated if it is stuck.

Here is a 47 I just finished cleaning and lubricating, the speedometer by the way is a King Seeley. I show the gears out and there is a lubricating hole at the top, take out the plug and wick and lube it there too.

You will probably find the last cable end broken-off in the hole. Once it is cleaned and lubricated you can spin the input shaft with your fingers and the needle will move.
 
If I may add to your thread with a similar issue. I have a 51 Ford Custom. Speedo quit working. I bought new cable, housing, and gear from Dennis Carpenter. Installed, still not working. I removed cable end at speedo and it is turning. I removed speedo. Cut end of old speedo cable off and inserted into drill. Tested, and speedo worked great. I feel the problem is the cable tip is not extending far enough into speedo to engage properly. Trying to avoid the rebuild if not necessary. Any suggestions appreciated.
