(8) Pitch Change Links.
The pitch change links, mounted between the swashplate assembly (180
apart) and the pitch horns of the tail rotor blades, incorporate two self-aligning bearings, and are nonadjustable.
(9) Drive Links.
The drive links, attached between the rotating swashplate and the tail rotor head
assembly, drive the rotating swashplate and are made of aluminum alloy and have sleeve bearings.
(10) Fork Assembly.
The fork assembly, mounted to the output shaft of the tail rotor gearbox, provides
mounting points for the tail rotor hubs and is made of titanium steel. The inboard section of the fork assembly
consists of two integral clevises 180 apart which provide attachment for the drive links, and a curving coupling to
provide positive interface with the tail rotor gearbox output shaft.
