Might want to check agrisupply or shoupe farm parts and do a search for seed disc or disc coverer. Should be able to find a disc with the bearing already installed.
remove the grease fitting and it was a 1/4 allen bolt inside remove lock nut on the other end of bolt need to heat around bolt to unscrew it that come like an assembly disc and bearings
