I just ordered a new spiral cutterhead from Grizzly for my 6 inch Ridgid jointer (610). The salesman told me that it is easiest to get new bearings, because the cutterhead does not come with them. He says it is easier to use new bearings instead of trying to remove the old bearings and installing them. I found the part number for the bearings ( 820722-5 and 820722-6). I don't know about cost or if I can buy these at my local Ace Hardware.
Has anyone else done this? Can you give me any tips or suggestions?
