Vehicle / Equipment Application |
Cummins QSK19 / QSK38 / QSK50-powered equipment for mining, generator power, marine, rail, oil and gas, construction, industrial power, agriculture, and forestry — including haul trucks, large excavators, drilling rigs, crushers, generator sets, marine vessels, compressor drives, pump units, switching locomotives, cranes, and stationary diesel power packs |
|
Application Type |
Engine-Specific Heavy Duty Fuel Injector |
Engineered around the Cummins QSK19 platform, the Y431K06139 fuel injector delivers a precise fit for the 19-liter inline 6-cylinder engine family running both HPI and MCRS fuel-system configurations. It supports QSK19 mining ratings of 506–800 hp / 377–597 kW and QSK19 G-Drive ratings of 500–550 kW prime and 550–600 kW standby, while also serving QSK38 and QSK50 CM2350 applications. Cross-referenced to F00BJ00042 and Y431K05857, it covers OE numbers 5375441, 4380190, and 4358048 with full suffix variant support.
Built for demanding industrial duty cycles, this common rail injector provides accurate fuel metering and fine atomization to maintain stable combustion across mining, generator, marine, rail, oil and gas, and construction service. Broad cross-reference coverage lets buyers search confidently by Bosch number, Cummins OE number, suffix variant, or engine model, simplifying sourcing for haul trucks, drilling rigs, generator sets, and stationary power packs.
To maximize injector life, use clean diesel fuel, follow scheduled fuel-filter replacement, perform regular water separation, and inspect the high-pressure system. Dirty fuel, water contamination, poor filtration, metal debris, and incorrect installation are common causes of early failure. Symptoms such as hard starting, rough idle, black or white smoke, misfire, power loss, and ECM injector fault codes indicate injector service is needed.
