Ok, seems the worm comes out very easily from the thrust bearing end, just as one would expect.
The idler bearing on the worm at the brake end of the machine is pressed in, and the worm won't go out that end, unless you pull that pressed-in bearing. So if your machine thrust-end is facing a wall, you have to unbolt it from the bedplate, and spin the machine around.
As far as "backlash", I'm referring to the gap between the crown and worm teeth. Maybe it's just confusion of terminology.
As I read your post, I think you are describing the "end play" of the worm, the distance it can slide back and forth horizontally within the machine. At any rate, my 22CT machine worm gear does not have a threaded end, no spanner nut, and no bolt to adjust it in any direction. It has a retainer plate, that locks the worm gear into the thrust bearing inner race. It's held on with three allen bolts, then safety wired.
Someone said that there are no adjustments for the wrom-to-ring engagement.
Going back tomorrow to finish up.
