About this part

Genuine Cummins piston ring, top for the QSK50 diesel engine, part number 2891820. The top piston ring seals the combustion gases above the piston and carries heat from the piston into the liner. Rings are renewed as a set at an overhaul: top, intermediate and oil ring for each piston.
