Installed the replacement guide system this morning. Operation was not too bad, took about 2 hrs including blade change and bearing adjustment. Bearings are larger and much easier to adjust but still a pain. Lower ones are defiantly easier to access. The bearings are pushed into place and then locked down while being held in place. I was hoping for a threaded adjustment for moving the bearing.
Couple of observations: If you have a newer model saw with a slotted hole in the frame for the lower bearing adjustment block, the lower wheel does not need to be removed. I found the lower bearing installation easier with the table removed which the directions do not address. I think this would also make elongating the hole in the frame of older models easier also instead of removing the wheel and drilling from below.
