Has anyone replaced arbor bearings on a Unisaw? If so, did you do it without
removing the table top, or did you remove it first?

This article makes it sound fairly simple without removing the top OR the arbor
bracket, only the arbor shaft:

The procedure on sawcenter.com has the top removed AND he removes the whole
arbor assembly as well.

My Unisaw is a model 36-844, circa 2001. I changed the belts yesterday, and
while the belts were off, I could hear the sound of dry clicking bearings when I
spun the blade by hand. There is no slop and they still spin freely but I
figured it would be best to go ahead and change them out.

I'll be replacing the originals with 2 quality Nachi bearings:

Any input?




I have never ever done this but here is something to think about.

I highly suspect that after removing the arbor and replacing the
bearings that the blade is not going to end up exactly where it was
before the bearing replacement. If you are worried about upsetting
blade alignment by removing the top you may not be making things easier
by not removing the top if the alignment still has to be reset.
