Apparently you want to keep us in the dark about your equipment. We need valid numbers from the equipment to know what you have. So since you think it is not necessary I am stepping of this thread as I got more important things to do than to guess at what you have. Its your baby now.

BTW this is for increasing the crankshaft OD size to fit a larger ID pulley, not to reduce the crankshaft OD size to fit a smaller ID pulley. And that particular adapter also extends the length of the crankshaft PTO end.
