I have another 416 enroute to me now, it is from the same batch as mine, and is also a torque version. I got the OK to tear it down completely and see what it is all about.

I did notice though when both gearboxes were open, the bevel and sun gearin the FCC did not sit solid, but would wobble. The Systema would not. That tells me that the gears did not sit precisely in a precise hole, and the lateral movement that ensued under load accelerated gear wear.
