Seems like a dumb question, but I can't find the answer anywhere.
When bolts (or clevis bolts) are used in controls that rotate (no bearings), you obviously couldn't torque the whole thing tight as it would not be free to move. I thought about using a bolt that is slightly too long, and torquing the nut till it stops but the hole for the cotter key would be several threads outside the castellated (or clevis) nut.
So my assumption is you just leave the nut slightly loose, and insert the cotter pin. I can't find any other answer, or any answer. Since clevis pins work the same way, This is my assumption.
Also, some of the thimbles used require bushings (flap drive). I think I remember reading here that the bushings should be slightly proud of the thimble, and then torque down the bolt onto the bushing. I couldn't find that in AC43, or anywhere else, either.
