The tail rotor drive shaft consists of five drive shafts and three hanger bearing assemblies. The drive shaft sections are constructed of aluminum alloy tubing with curvic couplings riveted to each end. All shafts are made and balance to a master shaft for interchangeability. Each hanger bearing assembly consists of couplings on a short splined shaft mounted through a single-row, sealed ball bearing in a ring-shaped hanger, equipped with mounting flanges for attachment to the tailboom. The assemblies, 42 degree gearbox, and 90 degree gearbox connect the transmission tail rotor drive quill to the tail rotor.
