Engineered for the demands of high-horsepower diesel service, OE number 4326639 is a Cummins fuel injector assembly built for the QSK60 MCR fuel system and listed across QSK60, QSK45, and QSK23 applications. This injector delivers accurate fuel metering, precision atomization, and high-pressure sealing with low leakage, supporting stable performance in the Vee 16-cylinder, 60 L platform rated across the 2000–2700 hp range.
With cross-number coverage for 4088427 and 4326779, this injector simplifies sourcing for global spare-parts distribution and engine overhaul programs. The MCR fuel system electronically controls pump and injector operation for injection pressure and timing, using an integrated accumulator at each injector to improve pressure stability. Every unit is flow-tested to support severe industrial engine service in mining, marine, generator set, oil & gas, rail, and heavy equipment fields across worldwide markets.
Injector fitment should be confirmed by engine serial number, CPL, calibration, emissions level, fuel-system type, and old injector number before ordering. Keep the fuel system extremely clean and follow the official Cummins service manual for torque values and installation sequence. After installation, prime the fuel system, check for leakage, scan fault codes, and test the engine under load to ensure reliable operation in demanding QSK60 duty cycles.
