FAQ

Q: How do I confirm this 3919565 piston kit fits my Cummins 6CT engine?
A: This kit is designed for the 6CT 8.3L engine with a 114mm bore. To confirm fitment, check your engine’s data plate for the model code (e.g., 6CT8.3, ISC8.3) and the existing piston part number. This kit replaces OEM numbers 3919565, 3923164, and 3802398. If your engine uses a different bore size or piston design, this kit will not be compatible.

Q: What does the piston kit include? Does it come with rings and a pin?
A: Yes, this is a complete piston kit. It includes one (1) aluminum alloy piston, one (1) steel piston pin, and one (1) set of piston rings (compression and oil control rings). It is ready for installation onto the connecting rod.

Q: What maintenance is recommended after installing a new piston kit?
A: After installing this piston kit, it is critical to follow standard engine rebuild procedures. This includes properly honing the cylinder liner to the correct cross-hatch pattern, lubricating the piston and rings during assembly, and following the manufacturer’s torque specifications for the connecting rod bolts. A proper break-in period with non-synthetic oil is also recommended for the new rings to seat correctly. Always consult your engine service manual for detailed instructions.
