Description

The Cummins Thick Wall Short Cylinder Liner 3800328 is a heavy-duty, precision-machined liner engineered for Cummins engine block 3934906 . This thick-walled, short-style cylinder liner is designed to restore proper cylinder bore geometry, compression sealing, and piston stability during diesel engine rebuilds. Featuring an overall length of approximately 9.212 inches and a 5.152-inch flange diameter , this short liner provides enhanced structural strength compared to thin-wall alternatives. Thick-wall short liners are commonly used in applications where added durability, wear resistance, and long service life are required without the added length of long-style liners. Manufactured from high-grade alloy cast iron , the Cummins 3800328 cylinder liner offers excellent heat transfer, resistance to scoring, and protection against cavitation. Correct liner installation is critical to reducing oil consumption, minimizing blow-by, and extending piston and ring life in heavy-duty diesel engines. This liner is typically replaced during Cummins diesel engine overhauls, in-frame rebuilds, and block reconditioning projects , making it a reliable solution for professional engine builders and fleet maintenance operations.
