  • 1949 Harley "45" Speedometer Drive Unit

    Upon undoing the speedometer cable from the rear wheel unit....
    How does one remove the speedometer drive unit?
    I saw the 1 small screw that allow the retainer clip to drop away.
    But then what?

    I suspect the drive unit is not 100% good; as the cable spins intermittently.
    Thanks for any help.

    After the clip is removed it pulls straight out. That is all.

      Hell...Of course it's that simple! Thanks!

      PS - Anyone know if its common for these reproduction drive unit gears are prone to fail? Or if I need to also be concerned with the gear the drive unit meshes up to?

        They were all somewhat a problem, original or replacement.

          I have replaced these a few times on my 45 and still can't get the speedo to accurately show my speed.

            Craig,
            What speedo is on there , original or repop? Not all internal ratios are the same.

              Hi Robbie,

              Sorry for the delay as I'm spending time on the Panhead side since I acquired a new toy.
              Anyway, don't think my speedo is original but not sure if it's a repop either. My needle moves around quite a bit too.
