  • Speedo Cable

    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!
    Thanks, Phil

    If the speedo is working, I would leave it alone, or send it to a professional to have it lubed. The cable on the other hand is easily greased by removing the dash, unscrewing the cable, pulling out the center cable and stuffing it with a moli grease as you shove the cable back into the sleeve.
    You wana look waaay far up da road and plan yer route because the brakes are far more of a suggestion than a command!

    I give the housing a squirt of oil, then slide the inner cable through some grease in my palm as I push it in the housing.

    Make sure the housing is properly routed and doesn't have any kinks.

      Make sure the speedo cable frame bracket is present and that it is mounted properly to the top of the rail.. Many cars have these missing which causes the cable to hang close to the exhaust

        If the speedometer is tight to turn, then I remove it from the housing and lubricate the bushings and gears. I use an Exacto knife and some rare earth magnets to remove the oval cover to clean out the old yellow hard grease, then give it a few drops of motor oil and some Mystik JT-6 High Temp red grease. I put a drop of oil on each bushing and gear.

        The last picture shows a speedometer I bought at a swap meet because the numbers were perfect, but a bushing had come out of place and was picked up by the speed dial magnet, which then jammed and snapped the shaft holding the wheel. These pictures are small and low quality because I had to use Google to go to photobucket to retrieve them, as photobuck now holds pictures for $400 a year ransom, if you want to see them as they were downloaded.

          Thanks all. I really appreciate all of the pointers.
          I have all of the support clamps in place. Do I have to disconnect the cable at the drive line to pull the shaft out to lube it?
          Sounds like more than my capabilities (or patience) on taking the speedo apart, Tom.

            post #2 remove the dash to pull it out the top

            disconnect the battery first
            remove the hold down clamp on the inside of the firewall this will give you more play when pulling the dash back to access the cable

            Newbie question: since I'm already working under the truck, can I pull the cable thru the sheath from the transmission end to lube it? TIA!

              Part Warning
              by DaWizard
              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

              Speedo not moving...
              by Beauford
              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?

              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.

              '34 Speedo Cable Routing Help
              by Reconnoiter
              Hi, new member here....I am in the tail end of restoration of my 34 Fordor and I need some help with routing the speedo cable before I start closing up the floorboards.

              Does the cable go through the same grommet in the frame as the grounding strap and out the same location as the fuel and battery cable? Or does it go just like I have it, underneath the frame edge and anti-chatter rod?...

              by KB9JLO
              OK I give up. Where does the speedometer cable go? I don't have one so I can't see where it should be...
              I assumed it went to the transmission but I don't think that's correct.
              I'm just curious - Got the Mike's email today for the speedometer cable special - figured out it's not the one for me. And then got to wondering where the heck it went.

              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...

              Pop out cable clamp
              by Aretino
              Does the pop out cable clamp that is secured by a head nut serve any significant purpose other than holding the cable?

              Speedometer Suddenly Siezed
              by Jedmundcars
              Took Clarabelle out the other day and during the ride the speedo quit. I checked it out and found broken inner cable. I ordered a new one and I thought I should check the speedo for fear of seizing. Cut about 3" off of the broken cable to test it and sure enough can't move it barehanded and would hate to use a drill for fear of tearing it up.
              I don't trust myself to disassemble it but thought...
