?Replacement is only $3.84 from .

?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 is 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... :-)

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?

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.
