PKO Stroke Adjustment
・Normally, modification of the PKO stroke is performed by replacing the PKO cam. However, replacement of the PKO cam requires fixing the PKO lever at the stroke end and in the case of large machines the machine cover has to be lifted up, and it becomes work that takes a lot of time.
・Because of this, Sakamura is developing a method to modify and adjust the PKO stroke without replacing the cam.
