CumminsRectangular Ring Seal Cummins Engine ISL – Engine QSL
Water Inlet Seal Cummins Engine ISL 8.9 – Engine QSL 8.9
Water inlet connection for the cooling circuit. It seals the joint between the components of the cooling circuit, preventing coolant leaks and maintaining the system’s proper seal. It is an elastomeric gasket designed to withstand coolant, temperature, pressure, and thermal cycling.
Observed on 6C 8.3, 6CT 8.3, 6CTA 8.3, ISC 8.3, QSC 8.3, ISL 8.9, QSL 8.9 engines.
It is advisable to always verify using ESN + CPL, the Cummins QuickServe catalog, or the original part number installed. This prevents errors caused by differences in model year, water inlet configuration, cooling system, and part replacements.

CumminsSealing O-Ring Cummins Engine ISL – Engine QSL
O-Ring Seal Cummins Engine ISL 8.9 /9 – Engine QSL 8.9 /9
It is located between the oil pump and its housing or fitting, providing a static seal between mating components and preventing leaks of oil or other fluids in the circuit where it is installed. It also appears in the section on the lubricating oil system/oil pump, but the exact location may vary depending on the CPL and configuration.
Observed on 6C 8.3 / 6CT / 6CTA, ISC 8.3, QSC 8.3, ISL 8.9/9, QSL 8.9/9, QSB 6.7, and ISB 6.7 engines.
We always recommend checking the ESN and CPL in the Cummins OEM catalog, because the same O-ring is used across different engine families, and the quantity and location may vary depending on the engine configuration.

CumminsSealing O-Ring Cummins Engine ISL – Engine QSL
O-Ring Seal Cummins Engine ISL 8.9 – Engine QSL 8.9
It seals the joint between mated components, preventing fluid leaks and maintaining circuit pressure. It is installed in a circular seat between two mated components of the fuel system, where it creates a seal that prevents diesel leaks and pressure loss. It is not an external engine block gasket. Some sources refer to this family of seals as Fuel Shaft O-Rings, so the application may be associated with the shaft/fuel system circuit area.
Observed on 6C 8.3 6CT 6CTA, ISC 8.3, QSC 8.3, ISL 8.9, QSL 8.9 engines.
We always recommend checking the ESN and CPL in the Cummins OEM catalog, because the same O-ring is used across different engine families, and the quantity and location may vary depending on the engine configuration.

CumminsSealing O-Ring Cummins Engine ISL – Engine QSL
O-Ring Seal Cummins Engine ISL 8.9 /9 – Engine QSL 8.9
Used primarily in the fuel pump system, at the point where the pump connects to its housing or mounting surface, Cummins officially specifies it primarily for 8.9-liter ISC/ISL Tier 3 engines. It creates a seal between the mating surfaces of the fuel pump system, preventing leaks and maintaining proper circuit integrity. Made of Viton/FKM, 75 durometer, a material resistant to fuels, oils, and high temperatures.
Observed on 6C 8.3, 6CT 8.3, 6CTA 8.3, ISC 8.3, QSC 8.3, ISL 8.9, ISL9 e QSL 8.9 engines.
Before selling or installing an engine, I always recommend verifying the engine’s ESN and CPL, either using Cummins QuickServe or the OEM catalog, or by checking the original number that was removed. The C/ISC/QSC/ISL/QSL family includes numerous revisions to the fuel system, and a cross-reference may only be valid for certain CPLs or configurations.

CumminsFront Crankshaft Seal Kit Cummins Engine ISL – Engine QSL
Front Crankshaft Oil Seal Kit Cummins Engine ISL – Engine QSL / QSL 9
The kit is fitted to the front of the crankshaft, at the front gear housing/front cover. Its function is to prevent engine oil from leaking around the crankshaft whilst it is rotating. It typically comprises a technical elastomer seal with a metal reinforcement and a metal support/cover.
Used on the 6C 8.3, 6CT 8.3, 6CTA 8.3, ISC 8.3, QSC 8.3, ISL, QSL / QSL 9 engines.
Always check the ESN and CPL before sale, as there may be variations within the ISC/QSC/ISL/QSL families depending on configuration, year and front gear housing.

CumminsFront Crankshaft Seal Kit Cummins Engine ISL – Engine QSL
Front Seal Service Kit Cummins Engine ISL – Engine QSL
It is located at the front of the crankshaft, in the gear housing/front cover area. It prevents engine oil from leaking around the front end of the crankshaft. The oil seal is typically made of an oil- and temperature-resistant elastomer with a metal backing; the wear sleeve is made of metal and creates a new sealing surface on the shaft when the original sealing surface is worn.
Used on the 6C 8.3, 6CT 8.3, 6CTA 8.3, ISC 8.3, QSC 8.3, ISL, QSL engines.
Always compare the ESN and CPL in Cummins QuickServe or the OEM catalog. Cummins allows you to search for parts using the Engine Serial Number and part number, and this is important because there may be different configurations of oil seals, sleeves, and front gear housings within the ISC/ISL/QSC/QSL models.

CumminsFront Crankshaft Wear Sleeve Cummins Engine ISL – Engine QSL
Front Crankshaft Quick Repair Sleeve Cummins Engine ISL – Engine QSL
It is positioned at the front end of the crankshaft, where it contacts the front oil seal. It creates a new, smooth surface on the area of the crankshaft worn down by the standard oil seal. This allows the crankshaft to be salvaged without having to replace it. It is typically made of hardened or wear-resistant steel, with a machined surface designed to contact the oil seal lip.
Used on the 6C 8.3, 6CT 8.3, 6CTA 8.3, ISC, QSC, ISL, QSL engines.
Always check the engine’s ESN and CPL, or consult the Cummins OEM catalog. There are variations in configuration and crankshaft seals, so compatibility with a specific engine must be confirmed before proceeding with a replacement.

CumminsRear Crankshaft Seal Kit Cummins Engine ISL – Engine QSL
Rear Main Seal Kit Cummins Engine ISL – Engine QSL
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.

CumminsFront Crankshaft Seal Kit Cummins Engine ISL – Engine QSL
Front Oil Seal Kit Cummins Engine ISL – Engine QSL / QSL 9
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.

CumminsRear Cam Bore Seal Cummins Engine ISL – Engine QSL
Camshaft Bore O-Ring Cummins Engine ISL – Engine QSL
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.
