On mine, I removed the c-clip and removed both bearings and reassembled. Instead of adding an extra washer, I've just tightened the thumb screw down. I've been riding it off and on for the last 4 months without any problems, although adding an extra friction washer does sound like a good idea while you've got it apart. I love mine, operating a rapid-rise XTR RD across a 9spd cassette.

BTW, I've also done the same mod to a set of 7 spd XCPro thumbies without any problems.
