See one of the many You Tube videos on replacing bearings on a Delta Unisaw.
It is necessary to remove the cast iron top to get to the bearings and thus takes considerable time to realign the table top afterwards. See You Tube video.
Pay particular attention to remove the threaded inside "nut" holding the outboard bearing in place (on some Unisaws) (My model is 34-801) and be sure to install the locking washer (with little tab on it) the correct way (flared side out not in). It locks the outboard arbor nut in place.

I found the correct bearings on this site, ordered them and when they arrived I replaced them. This is a Delta Unisaw and it was much easier to remove the top to gain access to the arbor and remove it to reach the bearings. The saw hums like it should. Thank you.
