Use this PTO directly to your Zenoah engine tappered crank shaft. Comes with a 6mm threaded shaft that is screwed to the mid-point of the engine PTO tapered shaft. Using a small amount of medium thread lock on both ends screw the Cluth-less Adapter onto the threaded stub and tighten. Designed to self-center and lock in place onto the tapered shaft. PTO end uses standard 1/4" square-ended cable.
Note: When measuring a square end cable, always measure between the corners point to point and not on the flats. The 0.250" measurement is taken from point to point, where-as if measured on the flat surface the incorrect number of 0.187" will be apparent.
