RV-7/8/9 builders don't apply, you have a different bellcrank set up. Anyway, I was installing this for the last time tonight and ran into a problem. The bellcrank installed in the mount with its quarter inch bolt (and washers/spacers) ok. But when I installed the AN3-10A bolt in the hole in the where the pushrod (rod end) goes, (and installed a thick washer and nylock nut), the amount of bolt sticking out of the nut created interference with the bottom (angle aluminum) mounting rail and the bellcrank couldn't move full travel. The bellcrank mounting rails, if you recall, are 1.5 inches apart and the bellcrank is centered between them. Van's old plans call for an AN3-10A bolt, thick washer and stop nut but that's obviously wrong. I checked my rail spacing just to be sure and yes I built them to the plans. So...I switched the bolt to an AN3-7 and with the thick washer and stop nut there is 2-3 threads sticking out of the stop nut. The bellcrank rotates freely but looking at the clearance between the end of the bolt and the bottom rail I would guess about 1/16 of an inch is all I have. This makes me nervous, the bellcrank mounting rails are 1/8 inch thick and that area is pretty stout but, the rod ends mount into the outer ends of the bellcrank itself (two pieces of 1/16 plate spaced apart by thick AN3 bolt washers in 4 places plus the center bearing mount acting as a spacer). If there is much flexing in the outer ends of the bellcrank in flight then it might be possible for the bolt end to come in contact with the mounting rail and ruin my day (life). I looked at going to an AN3-6A bolt but it doesn't look like there will be ANY threads sticking out of the stop nut when it's tightend (if I'm lucky and use a thin washer, I might get the threads to edge of the nylon in the end of the stop nut). Also if I used the -6A bolt I'll be violating the "grip length rules" (unthreaded bolt shank will not go all the way through the parts I'm bolting). Anyone remember having this problem? Did you use the -6A bolt or.... the -7A and live with the close clearances? How critical is it to adhere to the "grip length" rules?
