I am questioning what I have done regarding the attachment of the short aileron pushrod to the aileron bellcrank. The plans (W02) show a (3/16" ID x 5/16" OD x 3/8" long) flanged bushing inserted into the end of the short aileron pushrod, then a thrust bearing between the pushrod and the bellcrank. The plans note to file/sand the the thrust bearing to get a .005" - .015" clearance between the thrust bearing and the pushrod when the bolt is tight.
It seems to me that the 3/8" long flanged bushing is too long, and so when the bolt is tight there is way more than .015" between the thrust bearing and the pushrod. Not sure what I am missing here,
I had to shorten a lot of those bushings. I think I found a piece of steel that was the right thickness for the bushing, drilled a hole in it, slapped the bushing in and used the angle sander to sand it flush with the steel.
I also had to shorten those two bushings a lot.

Thanks, good to know I am not using the wrong bushing.

Interestingly, my kit came with mis-labeled parts. They were supposed to be SF610-6 flanges, which are 3/8" long. But what was actually in the hardware kit was SF610-4 flanges, which are only 1/4" long. Too short.
I ordered the correct ones from Aircraft Spruce and had to file away at them to get them to fit properly - this link will take you to the timestamp in a video clip where I worked on mine (though Iām sure you already know what to do):
