Here's what the problem probably is:  The sleeve that fits over the peg coming out of the rotar is probably loose.  You can cut a small sliver of thick plastic baggie and fold it over the peg.  Then add the sleeve, and screw the screw through the plastic.  This is an old repair man trick...saves a LOT of money and time.  You may have to change it every few months, but it works.  If you do not understand this procedure email me.
