Cummins original Common Rail Fuel Injector 6560-11-1114 4077076 4902827 4088429 Replacement for Excavator Sprayer Truck Auto Parts, for heavy duty diesel engine application original new injector

Part-number traceability supports accurate sourcing of the 6560-11-1114 fuel injector, an injector assembly and nozzle holder injector for heavy-duty diesel applications. It is primarily associated with the Cummins QSK23, a 23-liter inline six-cylinder engine family; aftermarket data also references QSK23 CM2250 and CM500 versions. Some catalogues connect it with the Komatsu SAA6D170E-3, subject to verification. Typical equipment includes excavators, mining machines, generator sets, oilfield power units, stationary industrial engines, marine auxiliary power units, and rail or intermodal power systems.

For cross-reference sourcing, 6560111114 is the non-hyphen search number. Reported Cummins-related cross or supersession numbers are 4902827, 4062090, and 4077076. Legacy Komatsu references include 6560-11-1110, 6560-11-1111, 6560-11-1112, 6560-11-1113, and 6560-21-2101. These numbers support parts matching, not blind-fit ordering. Buyers should confirm compatibility using the engine serial number, equipment model, old injector number, CPL, fuel system type, injector appearance, and original parts manual before purchase.

Within the QSK23 HPI-type fuel system, the injector receives fuel from the engine circuit, responds to electronic control signals, meters fuel precisely, and atomizes diesel into the cylinder to support stable combustion under high load. Its industrial design features a strong injector body, accurate fuel metering, and controlled spray atomization. Correct spray pattern, sealing, and response are critical for consistent operation in mining, construction, generator, and oilfield service, where downtime is costly.
