Cylinder Kit Complete Cummins Engine 6C 8.3 /L – Engine 6CT 8.3 /L – Engine 6CTA 8.3 /L

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.

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.
