Thanks to all for the replies. I did indeed get the bushing off using two screwdrivers. I cleaned it up a bit - just enough to keep me working - while i await the arrival of replacement parts. And I will be making a bronze bushing, at least, eventually.j

I'd say to just think of the replacement part as a kind of reverse
Murpy's Law: If it no longer matters whether or not you can get the old
bushing off without mangling it all up, it will of course come off with
no real drama. /Only if there is no replacement easily available/ does
Murphy's Law apply. Similar to the "butter-side-down" rule for dropping
your toast or the fact that it is exceedingly rare for your car to
conveniently break down right in your driveway, or perhaps in front of
your favorite local garage.
When mine seized up I used two flat screwdrivers to force it off, then
I lightly round filed the ends to clean up the prying marks, and
wetsanded the shaft down a bit until it was a sliding fit again. Since
then I have made a point of using lots of white lithium there ever
since. This isMurphy's Law <>
exception to the /mostly/ true opinion from those you may have read
about here who have decided those plastic gears need no lubricant...
except for that metal on metal bushing you discovered, that too is only
/mostly/ true... :-)
Good Luck!

I should be more specific. In addition to suggestions to keep it from
happening again, are there any recommendations for non-destructive
ways of separating the stuck bushing from the shaft?

polish shaft and use more lithium grease?

I was doing some general turning under power feed yesterday,
nothing elaborate, and all of a sudden the lathe stalled. After much
investigation I finally diagnosed the problem: the B/C gear bushing
has somehow fused or stuck itself to the B/C gear shaft on which it
rides. Seems absolutely welded. Right now I have it soaking in wd40.
Anyone had a similar problem and can give any advice?
Thanks,
Paul
