Had a similar problem with the "H" drive one touch system on a Performer. I must add the that solution in the linked thread is the ticket. The pictures are still gone, but the jist is still there.
You wedge a flathead screw driver between the rod and washer on the bottom of the bowl, in between the tabs of the "H" drive. This creates just enough room for you to twist the rod and get the ridge on the rod out of the groove on the washer. You then line up the ridge and pull it through the tab of the "H" drive. Customer service tells you just to "wiggle" it. Wiggling it will do nothing but drive you batty.
George, you're talking about the "Hex" drive one touch system which does have the thumb screw attaching the rod to the "Hex" drive. Not sure what year they made the switch from "H" drive to "Hex" drive.
