I need the bearing the flail/chipper shaft runs on. It is the one on the "outside" by the limb chute.

I think the number is 525MST,it is hard to read. The pat # is 4207659 on the housing. It looks like the bearing can be pressed out of the housing and a new one installed.

I am going to try the local auto parts stores but don't have much faith in that working unless I can locate a NAPA store.

Any suggestions or help will be greatly appreciated. I also want to purchase a new chipper blade while I have this torn down.
