The cylinder liner forms the cylindrical surface along which the piston and piston rings slide. It maintains the correct geometry of the cylinder, transfers heat to the engine block, and allows the engine to be rebuilt without having to replace the entire engine block. It is specified as a flanged cylinder liner and is supplied without sealing rings.
Cummins 6C-Series engines are also used in power plants, including the ISC 8.3, QSC 8.3, ISL 8.9 / 9, and QSL 8.9 / 9 models.
ESN – Engine Serial Number, CPL, Cummins QuickServe/OEM catalog, complete engine model and CM, stamped/cast number on the old liner, dimensional comparison of inner diameter/flange/length, or confirmation from Cummins.
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.
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.
