We just did the final assembly of my Grove airfoil gear and noticed that the NAS 6206-36 bolts (supplied by Grove) would turn in the holes after full torque was complete. When I measured the thread from the washer head under the nut to the end of the bolt, it was clear the bolts were a few thousandths too long. We'll have to add another washer.
By the way, these are the two outboard, hardened bolts on each gear - the ones that are hard to get at I've sent a note to Grove, but haven't heard back yet.
If you are installing or retorqueing (have no idea how to spell that) your bolts you may want to confirm the nuts have not bottomed. I'll update after I hear from Grove. I did confirm the thread and bolt length versus specs.
