Cummins original 6560-11-1114 Diesel Engine Fuel Injector Replacement for OEM 4088431 4902827 Fits QSK23 QSX23 SAA6D1170E-3 6D170 Engines for PC1250-7 PC1250-8 Excavators Trucks Autos Sprayers original new injector

Engineered for demanding industrial service, the 6560-11-1114 fuel injector supports reliable operation across the Cummins QSK23 engine family and Komatsu-related platforms. This 23-liter inline 6-cylinder diesel engine delivers construction ratings around 760–950 hp through an HPI fuel system, powering large excavators, mining machinery, generator sets, and oilfield equipment. The injector is manufactured as a robust replacement for high-load, continuous-duty applications where consistent fuel delivery is critical.

This diesel injector assembly features a strong injector body, accurate fuel metering, and controlled spray atomization for stable combustion. High-temperature resistance and sealing compatibility support long service intervals under severe operating conditions. Broad cross-number support—including 4902827, 4062090, 4077076, 6560-11-1110, 6560-11-1111, 6560-11-1112, 6560-11-1113, and 6560-21-2101—simplifies global sourcing, while optional flow test reporting and protective export packaging safeguard performance and shipment integrity.

Proper maintenance extends injector life: use clean fuel, replace filters on schedule, monitor water separators and oil condition, and perform return fuel testing. Common injector-related faults include hard starting, rough idle, black or white smoke, low power, high fuel consumption, and external fuel leakage. Diagnosis should combine ECM fault reading, cylinder cut-out testing, return fuel measurement, visual inspection, and injector bench testing.
