It seems like it does need to rotate the full 180* to engage/disengage. There seems to be a spring/detent at either end of the stroke.
That is good to know to pay attention to the gears. This pto isnt even from this transmission and hasnt been engaged to my knowledge. Is there a good way to double check that it will work? Measure angle of teeth and spacing?
