CumminsPiston Ring Set Cummins Engine 6C – Engine 6CT – Engine 6CTA
Piston Ring Set Cummins Engine 6C 8.3 / GTA 8.3 – Engine 6CT 8.3 – 6CTA 8.3
Used on Cummins engines in the ISL/QSL family and in 8.3–9 L applications. Located in the piston. Its function is to seal against combustion pressure, control lubricating oil, and transfer heat from the piston to the cylinder wall. Made of special steel/cast iron for piston rings.
Engines: Cummins ISL9, ISL/ISLe, QSL/QSL9; 6C8.3/GTA8.3 in some applications.
When purchasing a replacement engine, I recommend checking the ESN and CPL, because Cummins may use different piston/piston ring configurations within the same ISL/QSL family.

CumminsPiston Ring Set STD Cummins Engine 6C – Engine 6CT – 6CTA
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.

CumminsConnecting Rod Bushing Cummins Engine 6C 8.3 – Engine 6CT 8.3 – Engine 6CTA 8.3
Connecting Rod Bushing Cummins Engine 6C 8.3 – Engine 6CT 8.3 – Engine 6CTA 8.3
The bushing is pressed into the connecting rod foot and forms the sliding surface between the connecting rod and the piston pin. It serves to maintain proper piston alignment, reduce friction and wear, and distribute the loads transmitted from the piston pin to the connecting rod. Some aftermarket versions require boring or finishing after installation to achieve the correct pin tolerance.
It is used in various Cummins applications in the C, ISC, ISL, QSC, and QSL families.
Final compatibility must be verified using the ESN (Engine Serial Number), CPL, and the QuickServe/Cummins parts catalog, because not all configurations of the same engine necessarily use the same connecting rod or bushing.

CumminsConnecting Rod Bolt Nut Cummins Engine 6C – Engine 6CT – Engine 6CTA
Connecting Rod Bolt Nut Cummins Engine 6C 8.3 – Engine 6CT 8.3 – Engine 6CTA 8.3
It is a connecting rod bolt nut used to secure the connecting rod cap to the connecting rod body. It holds the connecting rod bolt—and thus the connecting rod cap—tightly in place on the crankshaft; it is a critical component of the connecting rod assembly.
Used on 6C / 6CT 8.3, 6CTA 8.3, ISC 8.3, and QSC 8.3 motors, as well as certain ISL, QSL, and M11 applications.
However, this must be verified using the ESN (Engine Serial Number), CPL, and the QuickServe catalog before placing the order.

Rocker Lever Assembly Cummins Engine 6C 8.3 – Engine 6CT 8.3 – Engine 6CTA 8.3
The rocker arm is part of the valve train. It receives motion from the camshaft via the rocker arm and pushrod and transfers it to the valves, enabling the intake and exhaust valves to open and close properly. It thus maintains proper synchronization between the valve train and cylinder operation.
Compatible Engines: Cummins 6C 8.3, 6CT 8.3, 6CTA 8.3, ISC 8.3, QSC 8.3, ISL 8.9, QSL9.
However, I recommend checking the ESN (Engine Serial Number), CPL, and engine configuration, because within the 6C family, there may be different rocker arm variants depending on the model year and cylinder head configuration.

CumminsNew Cylinder Head Cummins Engine 6C – Engine 6CT – Engine 6CTA
Cylinder Head Cummins Engine 6C 8.3 – Engine 6CT 8.3 – 6CTA 8.3
It is identified as a Cummins cylinder head for diesel engines. 6 cylinders, 24 valves. It is mounted at the top of the engine block, above the cylinders. It is secured to the engine block using cylinder head bolts, with the cylinder head gasket positioned between the cylinder head and the engine block. It seals the top of the cylinders and forms the upper part of the combustion chambers. Its main functions are to allow air to enter through the intake valves, to expel exhaust gases through the exhaust valves, to house and guide the valves, to support the fuel injectors, and to allow lubricating oil and coolant to flow through dedicated internal passages. Valves and springs included.
It is recommended for use with Cummins ISC 8.3 CM2150, QSC 8.3-500 HO CM850/CM2850, ISL 8.9 CM850, QSL 8.9 CM850/CM2850, QSL 9 M CM2250 L106, and 6C 8.3 series engines.
Always double-check; I wouldn’t assume the number is universally interchangeable on every QSL/ISL without verifying the ESN and CPL.

CumminsValve Cover Gasket Cummins Engine 6C – Engine 6CT – Engine 6CTA
Rocker Cover Gasket Cummins Engine 6C 8.3 – Engine 6CT 8.3 – Engine 6CTA 8.3
It is located at the top of the engine, under the valve/rocker cover. It is installed between the rocker/valve cover and the top of the cylinder head, creating the seal needed to prevent oil leaks from the valve train.
Fitted with Cummins 6C 8.3, 6CT 8.3, 6CTA 8.3, ISC 8.3, QSC 8.3, ISL 8.9, ISL 9, QSL 8.9, and QSL 9 engines.
Before making a purchase, I recommend always verifying the part using the ESN (Engine Serial Number) and, when available, the CPL in the Cummins catalog. Alternatively, you can verify it using the valve cover number, casting/stamped number, exact engine model, machine serial number/VIN, OEM parts catalog, or by comparing dimensions with the original gasket.

CumminsValve Cover Gasket Cummins Engine 6C – Engine 6CT – Engine 6CTA
Rocker Cover Gasket Cummins Engine 6C 8.3 /L – Engine 6CT 8.3 /L – Engine 6CTA 8.3 /L
The gasket is installed between the valve cover (rocker/valve cover) and the cylinder head. Its function is to seal the top of the cylinder head, preventing oil leaks and the entry of contaminants into the valve train area.
Used on Cummins 6C/L Series, ISC 8.3, QSC 8.3, ISL 8.9, and QSL 8.9/9 engines.
It should not be purchased based solely on the engine model. In particular, for ISL/QSL applications, you must verify the type of valve cover; one source specifies that it is intended for use with 8-bolt valve covers. For definitive confirmation, I recommend verifying at least one of the following: ESN (Engine Serial Number), CPL, the Cummins QuickServe catalog, the valve cover number, the number of bolts, the VIN/vehicle serial number, the parts manual, and a dimensional comparison with the original gasket.
