FAQ

Q: How do I confirm this liner will fit my specific Cummins NT855 engine?
A: While this liner (3055099) is the standard replacement for the NT855, we recommend cross-referencing the part number from your engine’s service manual or the original liner removed. Matching the engine serial number with our compatibility list provides the highest certainty.

Q: What preparation is required before installing this new cylinder liner?
A: Proper installation is critical. The engine block bore must be thoroughly cleaned, measured, and honed to specification. The new liner should be chilled before installation to ensure a precise, interference fit. We recommend following the official Cummins overhaul manual procedures.

Q: Do you supply matching piston and ring sets for a complete overhaul?
A: Yes. We offer a full range of compatible overhaul kits and components for the Cummins NT855, including pistons, rings, bearings, and gaskets. Contact our sales team for package deals to streamline your engine rebuild project.
