Cummins original 2881087 Diesel Engine Fuel Injector for QSK19 Engine, Replacement for OEM Parts, Excavator Attachment, Cross Reference 4955526, 2882078, 2867149 original new injector

The Cummins QSK19 Diesel Fuel Injector 2881087 is a heavy-duty fuel injection component for large Cummins QSK engine applications. It is designed for accurate fuel metering, high-pressure atomization and stable combustion, supporting engine power recovery, fuel economy and reliable long-hour operation. This positioning makes the injector suitable for professional diesel parts distribution, engine rebuild services and fleet maintenance procurement.

The main OE reference is 2881087, with related Cummins suffix references 2881087NX, 2881087PX and 2881087RX. Its documented Bosch and market cross-reference group includes 0 986 435 905, 0986435905, F00BJ00010, F00BJ00011, F00BJ60100 and Y431K55586, supporting catalog matching and buyer searches. Primary engine positioning covers QSK19 and QSK19 Tier 3. QSK38, QSK50 and QSK60 appear in broader aftermarket listings, but these applications require strict confirmation against the old injector number.

Equipment coverage includes diesel generator sets, G-Drive engines, mining trucks, excavators, marine propulsion and auxiliary engines, oilfield frac units, drilling rigs, rail equipment, industrial power units, construction machinery, and emergency or rental power systems. Before quotation or shipment, buyers should verify the engine serial number, CPL, old injector number, injector body marking, Bosch or Cummins number, fuel system type, ECM calibration and equipment model. This verification process helps distinguish valid cross-reference matches from adjacent part numbers and supports correct injector selection for each engine.
