Just a wee tip on assessing the rolling element bearings - thoroughly clean the one that appears to be good, and inspect the surfaces of both inner and outer races for any evidence of spalling (tiny bits missing). Do the same with the balls, too (you don't want spalling of the balls). If you find ANY evidence of it, change the bearing - it's in the early stages of failing.
It might be wise to change both bearings anyway, as a matter of course. That cutter block is a big lump, and the better the condition of the bearings, the better the finish you'll get in service.
