The primary transmission is composed of a pulley directly bolted to the
engine output flange, a poly-V belt transmitting the power, and an upper
pulley connected through a freewheeling unit to the gearbox input.
The power is transmitted :
• forward to main gearbox, and
• aft to the tail rotor transmission.
The main gearbox contains a splash-lubricated spiral bevel-gear set
which transmits power to the rotor mast. It is equipped with a filler plug /
breather, a sight gage and a self-closing magnetic chip detector.
The main gearbox upper and lower casings act as a tough central
structure, rigidly bolted in the middle of the fuselage structure.
