I have been having problems with the separator in my Rainbow E2 single speed from 2003, and I am wondering if anybody else has had the same problem and what they did to fix it. So, the separator WILL NOT COME OFF THE MOTOR SHAFT! I have tried and tried to get it off, but it will not even move. I tried spraying a small amount of PBBlaster where the shaft and the separator meet, and it still didn't do anything. The vacuum is in amazing condition, both physically and mechanically, all except for the separator! Any and all solutions are welcome. I have fixed a Rainbow in the past that was pretty dirty and the separator came right off. Mine isn't dirty at all. If anybody has any solutions, please share! Thanks!
