nu stiu daca are legatura dar, la motorul de broasca, care tot boxer e (ma rog, cu 4 cilindri), pistoanele se pun cu sagetile spre volanta. Un mecanic "priceput" mi le pusese spre evacuari drept care, rapid, mi s-a f...t un cuzinet.
later edit:
"You must first ascertain which is the front of the piston by locating the arrow on the piston head point towards the front of the engine. The axis of the piston hole to receive the pin is displaced by 1.5mm from the pistons diametric plane. "
