You may want to take a look at the starter section in the Vanguard service manual. When you do look at the plastic gear starter. I think you will find that the helix is what moves the pinion gear into place to engage the ring gear and once started the speed of the ring gear, the starter motor slowing and the spring is what retracts the pinion gear.
