If I remember correctly there is a collar on the shaft that the gear and a
small spacer fit on. The collar has two keys spaced 180deg apart. Once the
screw is out the gear and spacer should come off of the collar. The collar
is pinned to the end of the shaft. Depending on how it's currently geared
the spacer may be on the outside with the gear behind it or the reverse.

There's a pretty good image of the gears on one variety of that lathe near
the bottom of this page:

You're right to be careful with it because those gears are not very stout.
If it's tough to get off you might want to use something thin to get as near
as you can to the shaft to pry it off. Maybe a hacksaw blade?

On 2nd thought, I believe there is a bracket mounted behind it that holds
other change gears, similar to the one pictured he

It's locked on the outside of a collar the leadscrew shaft goes through and
is behind the gear. If you loosen the screw that clamps it on you can
probably use it to pull the gear off.

om...
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!
