FAQ

Q: How do I confirm that part number 3904167 fits my specific engine model?
A: This cylinder liner is specifically designed for the Cummins QSB6.7 engine platform. To confirm compatibility, please check your engine’s data plate for the exact model (e.g., QSB6.7-C240) and serial number. You can also compare the dimensions of your old liner with the specifications provided. If you are unsure, please contact us with your engine serial number for verification.

Q: What is the recommended installation procedure for this cylinder liner?
A: Installation should be performed by a qualified diesel mechanic. The liner bore and block must be thoroughly cleaned. The liner is typically installed using a specialized press tool to ensure it is seated correctly without distortion. After installation, it is critical to measure the liner protrusion above the block deck to ensure it is within the engine manufacturer’s specifications. Always follow the Cummins service manual for your specific engine model.

Q: Can I use this liner alone, or should I replace other components at the same time?
A: While you can replace a single liner, it is best practice during an engine overhaul to replace all liners together to ensure balanced compression across all cylinders. We also recommend replacing the piston rings, piston (if worn), and connecting rod bearings at the same time. For a complete top-end rebuild, consider our matching sets of pistons, rings, and liners to ensure component compatibility and long service life.
