The Cummins Cylinder Liner Kit 3802403K is a complete diesel engine liner solution designed to restore proper cylinder sealing, cooling efficiency, and long-term engine durability during Cummins diesel engine rebuilds and overhauls. This kit is ideal when replacing worn or damaged liners and ensures all critical liner-related components are renewed at the same time. Manufactured using OEM-grade materials , the cylinder liner included in this kit is precision-machined from high-quality alloy cast iron to withstand high combustion pressures, extreme operating temperatures, and continuous heavy-duty service . The finished inner bore promotes proper piston ring seating, reduced friction, and controlled oil retention for efficient combustion and extended engine life. Using a complete liner kit helps ensure correct liner protrusion, reliable sealing, and proper coolant isolation , which are essential for preventing compression loss, coolant leaks, and premature engine failure. Replacing liners as a kit during an overhaul improves reliability and reduces the risk of rework caused by reusing worn sealing components. The Cummins 3802403K liner kit is commonly used in Cummins diesel engine rebuild and overhaul applications , including on-highway trucks, industrial engines, and heavy-duty equipment requiring dependable internal engine components.
