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.
Check the Engine Serial Number (ESN) and CPL.
It is fitted to the front end of the crankshaft and serves to absorb and dampen the torsional vibrations of the crankshaft generated by combustion pulses. It normally consists of a heavy metal structure with an internal damping element; it is also marketed as a viscous vibration damper.
Used on C / 6C 8.3 – ISC – QSC – ISL – QSL engines.
Before making a purchase, I always recommend checking the ESN and CPL, or the Cummins OEM catalogue, as the same 8.3 L engine may use different dampers depending on its configuration, power output, year of manufacture and accessory layout.
It is not just a simple pulley. It is installed at the front end of the crankshaft and functions as a harmonic balancer mounted on the front end of the crankshaft. It serves to reduce torsional vibrations and oscillations of the crankshaft generated during diesel engine operation. It features a metal construction with an elastomeric/rubber damping element.

Always verify the ESN/CPL before placing an order, especially for ISC and QSL/L8.9 applications.
Installed in the EGR (Exhaust Gas Recirculation) circuit. It serves to create a seal between the EGR valve and the corresponding manifold/duct, preventing exhaust gas leaks during recirculation. A proper seal allows the EGR system to correctly route a portion of the exhaust gases back into the intake and contributes to the proper functioning of the emissions control system.
It is used on Cummins 6C 8.3, 6CT 8.3, 6CTA 8.3, ISC, QSC, ISL 8.9, and QSL 8.9 / 9 engines.
I wouldn’t automatically consider all ISC/ISL/QSC/QSL units to be compatible. To ensure a proper sale, you need to verify the ESN/CPL and EGR configuration, because specifications can vary depending on the model year, emissions certification, and engine build.

The pump is mounted on the engine using a two-hole flange. A push rod driven by the cam profile sets the internal impeller in motion; this alternately draws in and delivers fuel. Its function is to draw diesel fuel from the fuel supply system and deliver it to the injection pump at an appropriate pressure and flow rate.

It is an individual gasket installed between the cylinder head and the exhaust manifold. Its function is to seal high-temperature exhaust gases, preventing leaks between the cylinder head and the multilayer metal exhaust manifold.
Used on Cummins 6C 8.3, 6CT 8.3, 6CTA 8.3, ISC 8.3, QSC 8.3, ISL 8.9 / 9, ISLe, ISL G, and QSL 8.9 / 9 engines.
Before purchasing, I recommend contacting the distributor to verify the product using the Engine Serial Number (ESN) and CPL, especially for the ISL G, because some configurations require the updated gasket.
This kit is designed for the lower part of the engine and includes gaskets, O-rings, seals, and oil seals used during engine overhaul or rebuild. It is used to restore the sealing integrity of the lower engine components, primarily preventing leaks of oil, coolant, and other fluids, as well as ensuring proper sealing of the components during an overhaul.
Motors with verified compatibility: 6C 8.3, 6CT 8.3, 6CTA 8.3, ISC 8.3, QSCC 8.3, ISL 8.9, QSL 8.9
Final compatibility must always be verified using the ESN and CPL, because not all configurations within the same engine family necessarily use the same gasket set.
Gear Housing Gasket Cummins Engine 6C 8.3- Cummins Engine 6CT 8.3-Cummins Engine 6CTA 8.3
This is a set of gaskets and O-rings for the upper part of the engine, used during work on the cylinder head. It is designed to restore the seals after the cylinder head has been removed, preventing leaks. It contains various types of gaskets, O-rings, and sealing washers.
Motors with verified compatibility: 6C 8.3, 6CT 8.3, 6CTA 8.3, ISC 8.3, QSCC 8.3, ISL 8.9, ISLe 8.9, QSL 8.9
I always recommend verifying the Engine Serial Number (ESN) and CPL, as well as the ISC/ISL/QSL version. In particular, the included head gasket may have a specific thickness or configuration.

Liner w/o Sealing Ring Cummins Engine 6C 8.3- Cummins Engine 6CT 8.3-Cummins Engine 6CTA 8.3
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.
