Remove dash, unscrew speedo cable from speedo, drive car. If cable turns, repair speedo. If cable does not turn, pull cable out from inside to see how much is left inside cable housing, remove cable housing from turtle, pull partial cable from housing, replace cable with new cable from top, lube new cable liberally with molly style grease upon reassembly. Drive car.
If cable is good, send speedo to professional for repair.You wana look waaay far up da road and plan yer route because the brakes are far more of a suggestion than a command! -
The first thing i do is remove the cable from the turtle on the trans and spin it counterclockwise with a drill. If the speedo moves its in the cable connection at the turtle or a gear issue. If it does not move pull the dash and proceed from that point, also make sure the cable did not burn on the muffler. I have seen that many times because of a missing bracket at the frame3~ Tudor's & 1~ Coupe

I have found that if the speedo cable has been routed wrong it will place a slight kink right at the back of the gas tank and will be the place to break the inner cable due to the strain and wear at that point. Since you will not be able to pull the cable out from the bottom unless it IS broken, I have found it much easier to pull the cable from the top to find the break, if there is one. If the cable is not broken, you can still only pull it from the top, and this would be the best time to regrease it as you shove it back into the cable housing.
If the cable is broke then the pulling it out from the top will tell you how far away your problem is by the length of the pulled cable. It may indeed be that the clamp on the frame under the floorboard is missing or broken and allowed the cable housing to rest on the muffler cooking whatever grease you did have in the housing breaking the cable. This will also be shown by the length of cable coming out the top. Only after checking to be sure the cable does not turn will you need to crawl around under it to check the turtle and gear assembly.
If the first test by driving the car to see if the cable turns proves the cable is indeed good, then it won't hurt to grease the cable, and you now know the speedo itself is at fault and now that you already have the dash down, can easily be removed to be repaired.
Sorry I wasn't more descriptive earlier, wasn't quiet awake and mind was still muddled.
OH GEEZ, just thought of something I should have asked first......Was the speedo working then suddenly not?Last edited by DaWizard; 10-28-2017, 01:39 PM.You wana look waaay far up da road and plan yer route because the brakes are far more of a suggestion than a command!Comment

I have my speedometer removed for repair. While driving the car with the speedo cable disconnected and the cable hanging on the lip of the instrument panel, there is lubricant at the end of the open cable sheath and seeping out. Any ideas why the lubricant is climbing up the cable?07-19-2021, 02:20 PM -
Henry tells me in his "Model A Instruction Book" that I should lube the speedo cable every 5,000 miles. I don't know if mine has ever been lubed but I want to do all "Henry" says. What is the most effective way to perform this vital fete?
He also tells me that I should lube and re-calibrate the speedo itself every 10,000 miles?? Newby that needs some help!

I have a round face Northeast speedo, it has male threads for the cable. Apparently all the other speedos have female threads and I can't find a source for a cable. The pick-up is a '30 and has the keyed cable end at the torque tube. I am building a Pick-up basket case and don't have every little piece for it. Yes I could put in a different speedo, but at one time the part I need must have existe...11-24-2021, 12:47 PM -
Where the cables connect are they the same? My OD extension is for the early cable for the flag cable, my cable is squared cable. Looking to just replace the cable and get the speedometer working, gps is slow to react....03-15-2022, 09:22 AM -
On my Town Sedan the speed indicator wheel in the speedometer will frequently whip back and forth. I suspect the cause is a dry speedometer cable. I was fortunate to receive a fairly complete collection of Model A News and Restorer magazines. I remember reading about using STP to lubricate the speedometer cable/housing. I found two technical tip articles that were printed in Model A News written by...10-18-2021, 07:56 AM -
Since this is the second speedo cable I have purchased from Moss, I was informed they get them from Snyder's, so I am sending out this warning. The internal cable for the 28/29 is too short if you use the stock outer cable!!
It will fit but when pushed all the way into the depth of the turtle, it is short in making it all the way into the speedo square and you need it all the way into...09-18-2017, 09:30 PM -
Ok so I went for a short cruise as my vehicle is not DMV approved yet. The rebuilt speed does not work. It bench tested beautifully with a drill. I insert cable in speedo first and then the underside. I have rear on jackstands and it will go for a second and its like the cable jumps out. I'm assuming the speedo end. Any suggestions?11-22-2017, 09:17 PM -
Trying to get my speedometer working on my '31 Vicky. I assembled everything took a drive, speedometer worked for a couple of miles then quit. Changed nothing except to install a speedometer cable ordered from Mike's.
Troubleshooting, took the cable off the speedometer in the dash, a quick drive and clearly the inside cable spins. Took the speedometer out and ran it with my drill and...09-21-2018, 02:21 PM -
Does anybody know if the speedo cable clamp for the inside of the firewall is the same or different from the A17265 frame clamp??10-28-2022, 07:33 PM -
I am having a dickens of a time getting the speedometer end out of the transmission on my 57 bird. The clip came off with ease but adapter is stuck tight in the tranny. I’ve pre soaked with PB blaster but still won’t budge. I will try some heat. Just don’t want to destroy it.12-13-2019, 08:39 AM
