This is a diesel engine piston from the Cummins C-Series 8.3 L family, specifically for 6CTA8.3 turbocharged/aftercooled configurations. It is located in the engine cylinder/cylinder block. Its function is to transfer combustion pressure through the connecting rod to the crankshaft. It is made of an aluminum-alloy diesel piston; it features ALFIN’s reinforced ring-area configuration.
Engine: Cummins 6CTA8.3 / C8.3, selected CPLs
Verification using CPL/ESN is particularly important because, within the C-Series 8.3 family itself, there are pistons that look similar but have different applications and combustion geometries.
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.
