Hi, can anyone please explain to me why the vertical cylinder measure point is not in red circle? This is the same place as measure point at horizontal cylinder - between the crankshaft and mobile tensioner. But green circle at vertical cylinder is between crankshaft and immobile roller. This is not same bending (angle) belts. Violet line is not same as yellow line. So why should the frequency be the same? I think that if the frequency should be the same, the vertical belt must be more tight. Thank You.
