Там же на поршне спереди на юбке снизу выемка. т.е. он не симметричный. Или это рояли не играет ❓
На счет поворота на 180 градусов - опечатка 😊
Уже столько раз развинчивал двигун, что все перепутал.
Поршень там действительно по другому не поставиш.
Это я шатун однажды неправильно поставил, отверстием на нижней шейке назад, а в башке засело, что весь поршняк перевернул.
