When I had the rotor inspected by the tool & die instructor I asked him about the bearings. He looked at me and said .."what bearings?"  If you think about it he is right.  The 2 internal rotor surfaces in contact and ride on the 1/2" hardened steel shaft are machined cast iron.

The Emerson with rotor riding on shaft wear can be a tricky "fool ya" culprit making funky perplexing motor noise. You can have the blade off and front motor cover and grab the rotor firmly for play and good luck finding any.  :D  The culprit appears to be the rear rotor contact surface with excessive wear due to …..the weight of the blade?
