Looking forward to the teardown to reassembly. I have an old Zenith cleaning unit that I to am going to have to do the same thing to my motor. Always looking for tips. In my case I may take it to a nearby company to have it done. I could not stand the down time very long. I use this machine almost daily. Looking for an old standby. I wish I had another “cheep” unit just to fall back on. In time.
