    Im looking for someone to get my 56 olds Speedo calibrated, cleaned , and new digits put on the odometer wheels. It works, but its acting funky after so many years of sitting.
    I have some leads to spedo shops, but wondered if there were some guys on here that are into this stuff?
    Or anyone who has a good functioning 56 olds speedo..(it comes out of the pod)

  3. I just repaired the speedometer in my Safari and it really isn't too much to do.Don't know what yours is doing but on mine the bushing dried up and the speedo started squealing and the needle jumping wildly around.

    Pulled it out and found that there was a little br*** expansion plug(at least that is what it looked like)on the side of the housing where the shaft goes through.Popped it out with my pocket knife without damaging it and applied a little graphite suspended in a liquid(which evaporates almost immediately leaving just the graphite);re-installed the plug and re-installed in the car.Works great!
    A NOTE OF CAUTION:Be careful you don't put any pressure on the needle(mine is a disc)as it will cause it to rub against the housing and it won't function.Don't ask how I know that lol.
     
  4. I'm running a Harley "Police Special" speedo in the roadster from a T-5. Sent the works to North Hollywood Speedometer. They made a cable and added a domed gl***. All seems to work well...

    Never did any actual repairs, but revived a few. Are your odo wheels decal covered or are they the plastc kind with numbers molded in? This is something I've posted before:

    Here's my speedo repair technique: remove bezel and gl***, get speedo out of case. Get a tin can or something that allows you to set the speedo down with face up and secure balance, and study how you are going to hold the thing so neither your fingers nor the liquids to be used can touch the face or odometer. That stuff is VERY delicate and easy to destroy.
    Near the cable end, on what amounts to the speedo's main bearing, is a tiny br*** plug. Get it out--I usually manage to extract them unhurt by threading a tiny machine screw into the cup--and extract the piece of felt within.
    I then repeatedly flood this lube well with first kroil then WD40 as it frees up, sometimes liquid wrench if I feel something thinner is needed. You want lots of fluid to go in there and then leak out the bottom to dissolve and wash out the petrified lubricant and crud.
    When the shaft will spin freely by finger twirl--you should be able to get 5-10MPH easily by finger--soak several times with carb cleaner and then brake cleaner to remove all those miracle solvents. When drained and dry, I fillerup with Marvel Mystery Oil, based on my scientific observation that the only real speedo tech I ever saw in action used something that sure looked like MMO. Stuff felt&cap back into hole, well soaked. Let drain, re***emble.
    The multiple screwdriver tip sets you can get at discount stores contain a Canadian Robertson tip (square) that fits early Ford speedos and allows you to motor them up. You can also do a very rough test based on the supposed RPM of your electric tool, based on the speedo's calibration of 1,000 RPM=60 MPH.

    Here's a ratio test page:

    well mine is working..it just needs to be claibrated, cleaned, and new numbers put on the odometer wheels..

    Yeah they can be touchy little things..lol

    I can get by with it, i just thought if someone was into this sort of thing i would entertain sending it off to see if they could bring it back to the way it should be

    Model A odo decals are available in about 4 different sizes due to the multiple suppliers... you night well luck out, as sizes of odo wheels don't vary by a great deal.
    The decals are kind of a nightmare to install...some transfer them to sticky label stuff via computer magic, which would also allow sizing.

    Yes...what I am saying here is that there probably isn't anyone making '56 Olds decals, and all the odometers I know of are fairly close to the same size...only a few makers, and no great reason to change that particular bit over the years. With several different sets, one is likely to be right, and I think any geek could figure out the resizing if actually necessary and transfer from decals to stickies. I have installed the decals and it was absolutely no fun. Getting the results perfect would require several trials, while stickies would be very controllable.
