  • Posi-Drive Starter Drive
  • I'm attempting to remove the nearly new posi-drive starter drive from my failed (junk) Indian made aftermarket starter to install it on my OEM starter which has now been rebuilt.

    The new type starter drive does not use the spiral spring which can be collapsed in order to remove the pin holding the drive to the armature, and I find no way to move the washer back toward the starter in order to remove the pin.

    Moreover, in attempting to remove the drive, it has become extended and spinning it on a rotary wire wheel has no effect.

    So, two questions: What is the pricedure to remove the pin and how does one retract the drive?

    Thanks, in advance.

  • You have to get it spinning pretty fast to get the weights to sling out far enough to release the catch and allow the gear to retract. I believe the rectangular metal bits are the weights.

    You just have to squeeze the thing enough to get that pin out. Vice, C-clamp, whatever. The way I do it is I put a vice on the floor, open the jaws wide enough to let the shaft pass through, then place the drive on the vice jaws. Then I kneel over the starter and push down with my chest while pulling up on the vice with my left hand and pushing the pin through with my right.

  • Still unable to move it.

    Will try again when I can get a helper.

  • Thanks.

    I'll give it another try.

    Apparently, my small bench grinder will not spin it fast enough but I have a larger one. I'll try it.
