Piston -MALOSSI- MHR 47,6 with piston pin Ø 13 and rectangular piston ring - class 0

TIP: Always fit piston rings carefully. Piston rings made of cast material are only elastic to a limited extent and break relatively quickly. Some pistons have trapezoidal profiled piston rings (so-called keystone rings), these only fit in one installation position. If the ring does not move freely, please remove it carefully and reinstall it 'upside down'.
