Piston compression ring

A piston compression ring for sealing cylinder pressure, cataloged under PN 41-0092 in the cylinder and crankshaft section.

PN · 41-0092

This is a piston compression ring, listed in the catalog under part number 41-0092, appearing in the CYLINDER AND CRANKSHAFT section of the parts books. Compression rings ride in the top grooves of the piston and do the job of sealing the combustion chamber against the cylinder wall, keeping cylinder pressure where it belongs during the power stroke instead of leaking past into the crankcase.
