Thanks Rotorque,
I had rocked the shaft but not known the correct tolerances to look for. Problem solved. I have found with worn sprags the aircraft losses its crispness (if ever a bell can have crisp handling) and lags that little bit longer than usual to control inputs
I suppose if with worn lateral sprags and a shunt felt fore and aft (90 degrees later); if the aft sprag was worn the shunt would translate to the lateral plane in flight.?.
Cheers Mate
