Hello, I have my piston in the appendix. The side you see is the side to which the small arrow (the triangle) points on the piston bottom, or the opposite side of the two locking noses in the respective ring groove. I would like to know if this is the pressure side or the counterpressure side of the piston shaft, as this side is a little bit more worn out. My question (I did not remove the piston): – the arrow certainly points towards the outlet channel – the motor turns clockwise , if I stand right next to the vehicle ? Thanks for your answers cm
