Bosch original Unit Pump Injector for Truck Engine, compatible with 12LE7-350, 12L MIDR 06.24.65, primary part number 313GC5222M, replacement for OEM specifications original new injector

Designed for demanding heavy-duty environments, the Bosch 755 Series Fuel Injector 313GC5222M is a high-precision common rail diesel injector manufactured to Bosch OE fuel injection standards. It delivers precise fuel metering, optimized spray atomization, lower fuel consumption, reduced emissions, and reliable long-term operation for commercial vehicles, construction machinery, agricultural equipment, mining equipment, industrial power systems, and generator applications.

This injector offers extensive cross-reference coverage across Bosch, Cummins, and Komatsu parts databases. Primary Bosch numbers include 0445120231, 0986435597, and 0445120059, alongside Cummins references 5263262, 5263262NX, 5263314NX, 3976372, and 4945969, and Komatsu references 6754-11-3010, 6754-11-3011, and 6754-11-3012. It fits Cummins QSB4.5, QSB5.9, QSB6.7, and ISB6.7 engines, Komatsu SAA4D107E and SAA6D107E engines, and Volvo D5D, D7D, D7E, TAD760VE, TAD761VE, and TAD851VE industrial engines, serving Komatsu PC200-8, PC220-8, and PC240LC-8 excavators, WA320-6 and WA380-6 loaders, and Hyundai R290LC and R320LC excavators.

Operating within a high-pressure common rail system, the injector receives ECU commands at the solenoid, lifting the needle with exact timing so fuel is atomized through the DSLA128P5510 nozzle. The result is better combustion efficiency, improved fuel economy, lower particulate emissions, reduced engine noise, higher torque output, and improved cold-start performance. Hardened steel internal components, a wear-resistant valve system, corrosion-resistant materials, and laser-controlled fuel metering ensure extended service life, making 313GC5222M a dependable OE-quality choice for fleets, repair workshops, and equipment distributors worldwide.
