Cummins 3076130 Fuel Injector Assembly

The Cummins 3076130 is a PT (Pressure-Time) fuel system injector featuring STC (Step Timing Control) technology, engineered for the K19, KT19, KTA19, KTA38, K50, and QSK19 engine series. It delivers precise fuel metering and atomization under high injection pressures required by heavy-duty diesel applications. The injector assembly includes the nozzle, solenoid actuator, and internal wear components manufactured to Cummins standard specifications using high-speed steel and alloy materials for durability in severe duty cycles. This part supersedes and interchanges with Cummins part numbers 3062092, 4307428, 3095773, 4999492, and 3053124. It is applicable to marine propulsion (KTA19-M4), industrial power generation, mining haul trucks (e.g., Terex), and construction equipment powered by the aforementioned engine platforms. Installation requires calibrated torque settings and PT fuel pump synchronization per Cummins service manual procedures.
