can any of you please tell me how you get the lead screw gear off the
lead screw on a craftsman 109.20630 lathe? i've got the retaining
bolt out, and there seems to be nothing holding the gear onto the
shaft, but i can't get it off. the gear can be wiggled around a bit,
but doesn't pull off. i don't want to apply much force yet, in case
there's something i'm overlooking.

i assume the gear must come off somehow, since a threading chart i
looked at shows different gears on the screw for different
threading/turning conditions.

thanks!
