Doug,
On the M14 it is a shear coupling, not a shear pin. The two halves of the coupling are held in place by shear pins. Since the compressor on the Huosai engine is identical to the Russian compressor and the drive section of the compressors are identical, I would believe there is a shear coupling. The shear coupling mates the compressor drive to the accessory drive. Should the compressor seize during operation or there be a serious backlash, the couple halves shear apart and thus prevents serious damage to the engine accessory drive.
I also went through the IPB and could not find anything that resembles the shear coupling. I guess you will have to take a compressor off an engine to see.
