Product details
Engine overview
Cummins QSB4.5 engine assembly. The QSB4.5 is Cummins' four-cylinder 4.5 L electronic industrial platform. A reman replacement should preserve the original equipment's ECM, fuel-system, cooling and mounting specification—not simply its family name.
Cummins' QSB family data establishes architecture; it spans multiple ratings and regulatory versions. The supplied reman build requires serial-level confirmation.
