Bosch original Diesel Unit Pump Injector 313GC5222M 0986445001 0414755003 for 12L MIDR 06.24.65 A46 Truck Engine 0414755002 313GC5227M original new injector

Engineered for precise engine-level compatibility, the Bosch 755 Series Common Rail Injector 313GC5222M (OE 0445120231) delivers direct-fit performance across Cummins QSB4.5, QSB5.9, QSB6.7, ISB6.7 and QSB Series platforms, Komatsu SAA4D107E and SAA6D107E engines, Volvo D5D, D7D, D7E, TAD760VE, TAD761VE and TAD851VE industrial engines, and Hyundai R290LC and R320LC applications. This tailored design ensures accurate injection response for each supported powerplant.

Manufactured to Bosch OE standards, the injector features precision nozzle machining and laser-controlled fuel metering for consistent atomization. Hardened steel internal components, a wear-resistant valve system and corrosion-resistant materials extend service life under demanding duty cycles. Optimized injection timing and improved atomization reduce fuel consumption, while cleaner combustion lowers soot production and NOx emissions, supporting compliance across Komatsu PC200-8, PC220-8, PC240LC-8, WA320-6 and WA380-6 construction machinery, trucks, agricultural equipment and generator sets.

For reliable installation, inspect fuel rail cleanliness, replace sealing washers, verify the injector code and check electrical connectors before fitting. Follow OEM torque specifications, perform ECU adaptation and injector coding where required, and test fuel return flow. Replace fuel filters simultaneously and flush contaminated systems. Diagnostics can be performed using the Bosch EPS Test Bench, Return Flow Test, Cylinder Balance Test, Rail Pressure Analysis and ECU Fault Code Reading for accurate verification.
