I've had to use a different screw and extra washers for the reduction lever between the flybar and mixing arms. Irwin said to just locktight it because the radial bearing in the lever would pinch when the screw was tightened. Some washers and a longer screw fixed that.
A spacer between the bearings and then a small washer on bolt on each side. Then you can tighten the bolt as tight as you want and not pinch the bearings. That is how it is done on most helis.

Here is an example of what I am talking about. Look at the bell mixer and the bolt going thru it. You will notice there is a spacer between the two bearings and then a small washer against the head of the bolt. Then a small washer between the mounting surface and the bearing.
