Cummins original 4902828 Common Rail Fuel Injector Replacement for OEM Fit for QSK23 QSK60 K Series Diesel Engine for 1983-2006 Construction Machinery Cross Ref 4062090 4076533 original new injector

Engineered for demanding continuous-duty operation, the Cummins 4902828 diesel fuel injector serves as a dependable fuel-system component for QSK23 and QSK60 heavy-duty engines. The QSK23 is a 23L inline 6-cylinder, 4-cycle turbocharged and charge-air-cooled diesel engine rated at 760–950 hp / 567–708 kW, with generator platforms delivering 545–725 kW prime power and 600–800 kW standby power. Broad cross-reference coverage—including 4062091, 4077077, 4902828NX, 4902828PX and 4902828RX—simplifies sourcing for repair and distribution operations.

This injector supports accurate fuel metering, high-pressure diesel injection compatibility, and a stable spray pattern that promotes combustion efficiency and engine protection. Durable construction and effective leakage control help maintain consistent cylinder performance, while a design suited to fast replacement reduces downtime across mining, oilfield, generator, and construction equipment fleets.

Service life depends on clean fuel, correct filtration, water control, and proper installation. Replace fuel filters on schedule, drain the water separator, keep tanks clean, and monitor smoke and starting performance. Preventive diagnostics—fuel pressure testing, injector return flow testing, cylinder contribution testing, ECM scanning, connector inspection, injector number verification, and fuel quality inspection—help identify hard starting, rough idle, black or white smoke, power loss, and high fuel consumption before complete injector failure occurs.
