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.
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.
