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.
