When performing a professional engine overhaul, the precision of the Cylinder Liner determines the longevity of your equipment. For those maintaining the Cummins QSB4.5 series, the 3904166 part number represents the industry standard for thermal stability and wear resistance.
Whether you are managing a fleet of construction machinery or a single industrial power unit, sourcing the correct 3904166 (also referred to as 3904166) is critical to prevent premature piston ring wear and oil consumption issues.

Blow-by is often caused by a worn 3904166 Cylinder Liner or compromised piston rings. When the liner surface becomes glazed or scratched, combustion gases leak into the crankcase. Replacing with a new 3904166 sleeve restores the seal and engine compression.
Pitting on the outer surface of the liner (cavitation) can lead to coolant entering the combustion chamber. For the QSB4.5, regular coolant analysis and using high-quality 3904166 replacements with proper metallurgy can mitigate this risk.
Our 3904166 liners feature an OEM-standard tri-metal structure and are trusted by repair shops & equipment fleets worldwide for consistent performance in harsh environments.
