Hi all I found a fairly new oreck air cleaner at the thrift store last week. I turned it on and the fan was rubbing,so i took it apart and found the rubber coupling that holds the fan to the motor shaft was worn out.My oreck dealer in Tucson gave me a new coupling for free,so I gave it the spa treatment installed the coupling and she runs like new. I decided to put this on Ebay since we have a whole house system.
