    Does anyone know where I can get a speedometer drive gear for this tranny? The gear has 8 starts and is left hand pitch. The I.D. of gear is 1.375+ and O.D. is 1.930 +/- and width is .007. It could be steel or plastic. Any help would be greatly appreciated. Thanks

    I suspect that the gear there will be peculiar to the brand of car that the trans came from...the T-85 was used by quite a number of companies.

    I believe 55 56 Ford used that trans. The gears were different colors of plastic for the different tooth counts. If I am remembering correctly.

    this is what you need to consider...and since you didn't tell us what the transmission is from, or provide pics, it's hard to help!
     
  6. I'll go look at the one I have when I find it.Probably has the gear.

    Tire size, rear end, some mathematics. Do you want the drive gear or the driven gear? Correct me if I'm wrong but the drive gear is on the output shaft, the driven gear is the replaceable colored insert that you change to match tire size. Anyways, talking to a human being at a transmission shop gets this figured out real quick.

    You'll have to figger this all out if you are going to use an OEM speedometer, but if it's going in something with a custom dash, maybe one using round dial instruments like Stewart Warner or similar, consider the satellite/GPS speedo from Speed Hut.
    I have one in my roadster, and the difference in appearance is almost impossible to see, except the small logo on the dial. They have a deal on their website that allows you to choose dial face, Font, needle, etc. Considering all the research and parts chasing it eliminates, if it's compatible with your remaining instrument panel, it's 5he way to go IMO.

    I need the drive gear because it drives the governor for the overdrive. Transmission shops today have no idea what a R11 overdrive is. :mad: OH, I made a mistake on width dimension I original post...it's .700" not .007.

    Oop0's!!!!!!!!!!!!! You're correct, I was forgetting about the OD, unless you can wire it up to work off switches manually instead of using the governor.

    IIRC, the T85 used the same speedo gears as the T10 and they're still readily available.

    Studebaker International stocks quite a few. www.studebaker-intl.com
