It ensures the combustion chamber remains airtight and allows for the controlled flow of high-pressure, high-temperature exhaust gases toward the manifold and the turbocharger. The kit includes an exhaust valve and retaining cones.
Used on Cummins Heavy Duty and Medium Duty engines (industrial, marine, automotive, and construction applications) in the ISC (8.3L), ISL / ISL9 / ISLE4 (8.9L), QSC8.3, QSL9, 6C8.3, B4.5, and ISF3.8 engine series. Models from approximately 2002 to the present.
Always verify using the Engine Serial Number (ESN).

The cylinder liner is installed inside the cylinder block, forming the cylindrical surface along which the piston moves. The kit is designed to provide the piston’s sliding surface, maintain the correct cylinder geometry, rebuild the cylinder during an engine overhaul, and ensure a proper seal using the included sealing elements. The kit includes a cylinder liner and a liner seal.
Installed on Cummins 6C/L Series, ISC 8.3/L, QSC 8.3/L, ISL 8.9/9, and QSL 8.9 engines.
Generally manufactured up to 1990 / before the 1991 block modifications. To avoid errors, I recommend verifying at least one of the following: Engine Serial Number (ESN), CPL, Cummins QuickServe catalog, block casting number, engine production year, original cylinder liner dimensions, and the number stamped on the old cylinder liner. In particular, it is important to distinguish the early pre-1991 block from later versions.
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.
The kit is installed inside the engine block. The cylinder liner fits into the block’s bore; inside the liner, the piston, piston pin, connecting rod, and crankshaft operate. It forms the thermal assembly of the individual cylinder and must contain combustion pressure, guide the piston, ensure compression sealing, control the oil film via the piston rings, and maintain the correct piston-to-liner clearance. The complete Cummins cylinder kit for engines in the C Series 8.3 L family, or industrial/on-highway/off-highway applications using the correct 8.3 L block configuration, with STD configuration, for the late thick-walled cylinder block #3934899, effective 01/05/1998.
It is used in Cummins 6C 8.3 L, 6CT 8.3 L, 6CTA 8.3 L, ISC 8.3, QSC 8.3, ISL 8.9/9, and QSL 8.9/9 engines.
Compatibility varies by engine CPL, ESN, piston configuration, and cylinder block. Verify the engine serial number before ordering. This wording allows you to correctly include QSL, ISL, QSC, and ISC without incorrectly stating that it fits all of these engines. Cummins itself recommends identifying parts by ESN/CPL and piston configuration.

The same Series C family can utilize different bowls depending on the application—road, industrial, or marine—or the position of the sump.
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.

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.

The kit provides a seal at the rear of the crankshaft, preventing engine oil from leaking at the point where the crankshaft exits the engine block toward the flywheel/transmission housing. It is therefore installed at the rear of the engine block, on the flywheel side. The sealing component is typically made of a technical elastomer that is resistant to oil and high temperatures, combined with metal support/reinforcement elements.
Compatible engines: 4B, 4BT, 6B, 6BT, 6C, 6CT, 6CTA, ISB, QSB, ISC, QSC, ISL, QSL
However, we recommend checking the ESN/CPL before the sale: not all configurations within the same engine family necessarily use the same oil seal.
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.
