The same ISC/ISL family can use different bowls depending on the application—road, industrial, or marine—or the position of the filter housing.
The ESN remains the most important check,
because the same engine model can be fitted with different
parts depending on the year of manufacture or the CPL.
Oil Pan Gasket Cummins Engine 6C 8.3 – Engine ISC 8.3 – Engine QSC 8.3
The ESN remains the most important check,
because the same engine model can be fitted with different
parts depending on the year of manufacture or the CPL.
Some catalogs extend the application to ISC, QSC, ISL, and QSL. Final compatibility must be verified using the ESN and CPL, as the oil pan may vary depending on the configuration and application.
Oil Pump Cummins Engine ISC 8.3-Cummins Engine QSC 8.3
The kit is fitted to the front of the crankshaft, at the front gear housing/front cover. Its main function is to prevent engine oil from leaking around the crankshaft whilst it is rotating. The oil seal is normally made of an oil- and heat-resistant elastomer with a metal support ring.
Used on the 6C 8.3, 6CT 8.3, 6CTA 8.3, ISC 8.3, QSC 8.3, ISL, QSL / QSL 9 engines.
Final compatibility must always be checked using the engine’s ESN and CPL, or the Cummins OEM catalogue. Within the QSL family, there may be variations depending on the year, configuration and CPL; therefore, the engine family alone does not guarantee 100% suitability.
Front end of the crankshaft, pulley/damper side. Prevents engine oil from leaking around the front end of the crankshaft. Oil-resistant NBR nitrile rubber, metal reinforcement, and hardened steel wear sleeve. The kit includes an oil seal, wear sleeve, and dust shield.
Documented applications for Cummins 6C / 6CT 8.3, 6CTA 8.3, ISC 8.3, QSC 8.3, ISL 8.9, and QSL 8.9 / QSL 9 engines.
We recommend always checking the ESN and CPL, because Cummins may use different front oil seal configurations depending on the series, model year, and engine configuration.

Piston Cooling Nozzle Cummins Engine ISC -Cummins Engine QSC
It connects the piston to the connecting rod. It allows the piston and connecting rod to move relative to each other and transfers the combustion force to the connecting rod.
Confirmed applications: Cummins ISC, QSC, ISL, QSL; it is also documented for engines in the 6L/6LT family.
To ensure exact compatibility, I still recommend checking via ESN/CPL, because not all configurations use the same connector.
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.

Retainer – Valve Spring Cummins Engine ISC 8.3-Cummins Engine QSC 8.3
Used on Cummins engines in the ISC and QSC 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 ISC 8.3, QSC 8.3 and ISL G in some applications.
When purchasing a replacement engine, I recommend checking the ESN and CPL, because Cummins may use different piston/piston ring configurations.
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.
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.
transfers combustion force from the piston to the crankshaft, converting piston reciprocating motion into crankshaft rotation.
For Cummins 6C 8.3, 6CT 8.3, 6CTA 8.3, ISC 8.3, and ISL 8.9 / 9 engines. Some aftermarket catalogs also extend the application to QSC 8.3 and QSL 9 Marine / Industrial engines.
Always verify compatibility using the Engine Serial Number (ESN), CPL, and the original connecting rod number before installation.
Secures the connecting rod cap to the connecting rod, ensuring proper tightening around the crankshaft journal. M12 × 1.25 thread. High-strength steel. Grade: 12.9.
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.
To ensure full compatibility, I recommend checking the ESN (Engine Serial Number), CPL, and connecting rod number, because there may be different configurations within the ISC/ISL/QSC/QSL/M11 family.
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.
It is installed between the connecting rod head and the crankshaft connecting rod journal. It creates a lubricated sliding surface that reduces friction and wear and maintains the proper clearance between the connecting rod and the crankshaft. It is used when the crankshaft connecting rod journal has been ground down by 0.010″.
Replacement parts for Cummins C / ISC / QSC / ISL / QSL applications.
Before the sale, it’s a good idea to check the ESN, CPL, and the actual length of the crankshaft.
It is installed between the connecting rod head and the crankshaft connecting rod journal. It creates a lubricated sliding surface that reduces friction and wear and maintains the proper clearance between the connecting rod and the crankshaft. It is a standard (STD) bronze bushing. It should not be confused with undersize or repair versions intended for ground crankshafts.

Before considering them 100% interchangeable, I still recommend verifying them using the ESN (Engine Serial Number), CPL, and QuickServe, because their application may vary depending on the engine configuration.
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.
It transmits mechanical motion to the pumping section of the high-pressure pump, it operates within the fuel pump drive system. The roller follows the control profile and transfers force to the pump, enabling the pump to generate the pressure required for the fuel injection system.
The part is also listed for use in Cummins ISC 8.3 and QSC 8.3 / PACCAR PX-8 applications, while other catalogs also list it for use with ISL 8.9 / ISL 9, QSL 8.9 / QSL 9 and the CCR1600 pump.
However, to ensure exact compatibility, you must verify the ESN (Engine Serial Number), CPL, pump model, and pump part number, because there may be different configurations within the ISC/ISL families.
It seals the rear opening of the camshaft housing, preventing engine oil leaks. An aftermarket catalog also refers to it as the camshaft plug O-ring.
For engines in the C, ISC, QSC, ISL, and QSL families; Cummins specifically lists ISC/ISL 8.9 L Tier 3 applications.
Before considering them 100% interchangeable, I still recommend verifying them using the ESN (Engine Serial Number), CPL, and QuickServe, because their application may vary depending on the engine configuration.
