Identifies a piston pin retaining ring. It is a small but essential component of the piston-connecting rod assembly and is typically installed in pairs per piston, one on each side of the pin. Its function is to axially secure the piston pin within the piston seats. Spring-steel retaining ring.
It has a wide range of applications in the Cummins C / ISC / QSC / ISL / QSL / L family.
Piston Ring Set STD Cummins Engine 6C 8.3 – Engine 6CT 8.3 – Engine 6CTA 8.3
This is a set of piston rings. They perform three essential functions: they seal the combustion pressure between the piston and the cylinder, control the oil film on the cylinder wall, and help transfer heat from the piston to the cylinder.
Used on Cummins C Series, ISC 8.3, QSC 8.3, ISL, and QSL/QSL9 engines.
For QSL/ISL/ISC/QSC, it’s always a good idea to check the ESN and CPL, because the same engine may use different pistons and ring configurations depending on the version and model year.
It is mounted in the engine block and directs a jet of oil toward the bottom of the piston, helping to reduce its temperature and lubricate the piston-cylinder assembly. It is located in the cylinder block, where its function is to spray oil under the piston for cooling and lubrication. It is made of metal, primarily steel.
