Description

The Cummins Thin Wall Cylinder Liner 3802370 is a precision-machined engine liner designed for use with PLK9247 piston applications and the Cummins engine block 3802265 . This thin-wall cylinder liner restores proper bore geometry, compression sealing, and piston-to-wall clearance during diesel engine rebuilds. Engineered with exact OEM specifications , this liner features an approximate length of 9.33 inches and a 5.223-inch flange diameter , ensuring proper seating and alignment within the engine block. Thin wall liners are commonly used in applications where maintaining original block dimensions is critical while achieving a reliable cylinder surface for piston operation. Manufactured from high-grade alloy cast iron , the Cummins 3802370 cylinder liner provides excellent wear resistance, heat dissipation, and long service life under heavy-duty diesel operating conditions. Correct liner installation is essential for preventing oil consumption, blow-by, and premature piston or ring wear. This thin-wall liner is typically replaced during Cummins diesel engine overhauls, in-frame rebuilds, and piston replacement jobs using PLK9247 piston components.
