We split a bearing race and used it to support the steel inner part of the 
worm gear wheel.  The shaft pressed out easily.  It did take a bit more work 
to get the inner race for the top bearing off, but it still was no big deal. 
OTOH The sealing surface for the upper oil seal is pretty well shot.  The 
surface for the bottom seal is a bit rough but I think that could be 
salvaged. Still I have to be able to use both ends of the gear.

There are now five and I have reduced the size to 100K per file, give or 
take a tad. I added two that show the upper and lower sealing surfaces.


There's a bit more information at the bottom of my tower project page
