The crankcase has three cylindrical bores in which a cup with a driving gear, a lid with a driven gear and a tail rotor control rod assembly are installed. There are partitions in the crankcase cavity for installing bearing supports for bevel gears.

The tail gear is attached to the flange of the end beam.
