Cummins original High Pressure Common Rail Fuel Injector Y431K05392 2867147 0986435615 Replacement for OEM, Cross Reference 0986435900 for QSK QSK19 QSK38 QSK50 QSK60 Diesel original new injector

For Cummins QSK-series service work, the Y431K05392 fuel injector provides a clearly cross-referenced common rail replacement option. It is primarily associated with the QSK19 and also listed for QSK38 and QSK50 applications, including CM2150 MCRS and CM850 MCRS variants. Related numbers include Bosch F00BJ00000, F00BJ00001 and 0986435900, plus Cummins 2867147, 2867147NX, 2882077 and 2882077NX. The QSK19 is a 19-liter inline six-cylinder diesel; Cummins lists QSK19 G-Drive ratings of 500–550 kW prime and 550–600 kW standby.

The injector controls diesel fuel delivery into the combustion chamber, influencing starting performance, idle quality, smoke level, exhaust temperature, fuel consumption, cylinder balance and power output. That makes dependable injector selection especially important in high-load, long-hour MCRS service exposed to vibration, mining dust, marine humidity and generator, rail or oilfield duty cycles. Typical equipment coverage includes generator sets, haul trucks, large excavators, drilling rigs, marine vessels, locomotives, pumps, compressors and stationary power packs.

This product is suited to diesel repair shops, QSK engine rebuilders, generator and marine service teams, mining fleet maintenance, oilfield and construction equipment specialists, and global parts distributors. Before ordering, provide the engine serial number, old injector number, engine model, CPL, ECM type, equipment model, emissions tier and quantity. Final compatibility should be verified against the original injector, ECM calibration, fuel-system type and equipment model before shipment.
