It is installed in the cylinder block and forms the surface against which the piston operates. It provides the piston’s sliding surface, maintains the correct 114 mm bore, transfers heat to the block/cooling system, maintains compression and the correct cylinder geometry, and allows for engine overhaul without having to completely replace the cylinder block. The liner is typically made of high-strength cast iron or a cast iron alloy, properly machined and finished on the inside to withstand wear, pressure, and temperature. The kit consists of a cylinder liner and a cylinder liner seal.
Installed on Cummins C-Series engines such as the 6C 8.3, 6CT 8.3, and CTA 8.3, 6CTAA 8.3; it is also mentioned for the ISC, QSC, ISL, and QSL models, though this has yet to be confirmed.
Always check the ESN (Engine Serial Number), CPL, Cummins QuickServe/OEM catalog, cylinder block number, number stamped on the old liner, flange diameter, liner length, and engine year/configuration. This is particularly important because there are early and late/thick-wall versions of the liner.
This is a diesel engine piston from the Cummins C-Series 8.3 L family, specifically for 6CTA8.3 turbocharged/aftercooled configurations. It is located in the engine cylinder/cylinder block. Its function is to transfer combustion pressure through the connecting rod to the crankshaft. It is made of an aluminum-alloy diesel piston; it features ALFIN’s reinforced ring-area configuration.
Engine: Cummins 6CTA8.3 / C8.3, selected CPLs
Verification using CPL/ESN is particularly important because, within the C-Series 8.3 family itself, there are pistons that look similar but have different applications and combustion geometries.

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 6C, 6CT, 6CTA, 6CTAA; it is also documented for engines in the 6C/6C L 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.
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.

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
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.
