14 is where the pitch change arm and the TR servo attachment is on a 365.
Gray - what they call a duplex bearing is what allows you to superimpose horizontal pitch change movement onto the rotating drive shaft - you probably already knew that but I though I'd clarify just in case.
I'm well aware of the function yes. I've overhauled alot of 120 and 130 TGB's.
Its likely a similiar position to it enough that I can relate it to the 169 at least.
They use a double row ball bearing that seems undersized for it's function. Only seen a couple failures though, but nothing catastrophic.
I just wasnt sure where it was located and how it was connected to the nut issue previously.
I am not familiar with the 169 directions of rotation, or left/right hand threads for that nut. but can anyone say for certainty what could happen if the bearing seizes? will it rotate that shaft and un-thread the nut with enough force to overcome the torque, and safety locks?
