On my 2001 400ex, on the right side where my clutch is there is a bearing that goes over this collar then the clutch basket goes over it. I attached a picture of the diagram. But the bearing only comes up on a 2005 and up and below 2005 it will show up on the diagram but not on the list. I ordered the bearing because I couldn’t find it anywhere and the diagram showed it, but it doesn’t fit. The clutch basket fits on their with no play without the bearing. So should I go without the bearing?
