Cummins original Diesel Common Rail Injector 4928349 Replacement, Cross Reference 4087887, 4928346, 4010163 for Excavator, Mining, Machinery Repair Shops original new injector

At the final, precision stage of diesel fuel delivery, the Cummins 4928349 injector is positioned for high-horsepower QSK series engines, especially QSK60 MCR fuel system applications. The QSK60 platform is a 60.2 L V16 used across marine, mining, oil and gas, generator and industrial power markets. On MCR versions, the High Pressure Modular Common Rail system electronically controls injection pressure and timing, while integrated injector accumulators help improve pressure stability. The injector must meter fuel into the combustion chamber at the required timing, pressure and spray pattern.

For purchasing and cross-reference checks, 4928349 is the main OE number and 4928349RX is a commonly listed reman or exchange reference. Market-associated numbers include 4928336, 4326639, 4088427, 4326640, 4088426, 4326780, 4326781, 4010160, 4087891 and 4010158; these are search and reference aids, not guaranteed official replacements. Typical equipment coverage includes QSK60-powered mining trucks and excavators, marine propulsion and auxiliary engines, generator sets, oilfield pumping units, industrial power units and rebuild projects. Some sources also associate the injector with QSK45, requiring careful confirmation.

Before quotation and shipment, buyers should supply the engine model, engine serial number, CPL number, old injector number, injector photos, fuel system type, application, quantity and condition requirement. This verification helps reduce the risk of poor combustion, rail pressure problems, cylinder imbalance, smoke, misfire or engine damage caused by incorrect injector matching.
