To do this I had to loosening the two small hex nuts on the handle slightly then turn the handle clockwise (tighten) about 180 degrees. You must hold the back (small nub) of this shaft with pliers or it will turn. This brought everything tighter and voila! No noise anywhere. Perfect function. <o:p></o:p></SPAN></FONT></LI></OL> <P class=MsoNormal><FONT face=Arial size=2><SPAN style="FONT-SIZE: 10pt; FONT-FAMILY: Arial"><o:p> </o:p></SPAN></FONT></P> <P class=MsoNormal><FONT face=Arial size=2><SPAN style="FONT-SIZE: 10pt; FONT-FAMILY: Arial">The pictures show all the important stuff. The last picture shows the space (lost motion) that needed to be removed. That is where the pen is pointing. It took a few minutes to discover this procedure, but it worked well. Too many turns and the wheel won’t turn, too loose – noise.<o:p></o:p></SPAN></FONT></P> <P class=MsoNormal><FONT face=Arial size=2><SPAN style="FONT-SIZE: 10pt; FONT-FAMILY: Arial"><o:p> </o:p></SPAN></FONT></P> <P class=MsoNormal><FONT face=Arial size=2><SPAN style="FONT-SIZE: 10pt; FONT-FAMILY: Arial">I hope this helps someone else.
