Engineered for demanding Cummins ISLe and QSL diesel platforms, the BOSCH 0445120304 common rail injector delivers reliable high-pressure fuel delivery across heavy-duty truck, bus, generator and construction machinery applications. This 120 Series CRIN unit is identified by primary OE number 0445120304 and covers a wide cross-reference range for accurate sourcing and inventory matching.
This injector carries authorized cross numbers including 5272937, 5283275, and their remanufacturing variants 5272937NX, 5272937PX, 5272937RX, 5283275NX, 5283275PX and 5283275RX, along with nozzle reference DLLA144P2273, 0 433 172 273 and valve reference F 00R J02 806. Its high-pressure common rail design supports precision fuel metering, improved atomization, engine power recovery, fuel economy and heavy-duty durability. Application must always be confirmed by the original injector number, engine serial number, fuel system calibration and ECU coding requirement.
Proper maintenance extends service life: use clean diesel, replace fuel filters regularly, drain the water separator and perform return-flow and rail pressure testing. Common failure symptoms include hard starting, rough idle, black or white smoke, power loss, knocking, high fuel consumption and ECU fault codes. Recommended diagnostics include cylinder balance testing, injector correction value reading, high-pressure leak inspection and professional common rail test bench verification for dependable fleet and remanufacturing results.
