Bosch original Common Rail Fuel Injector 109962-0042 Replacement for OEM, Cross Reference 109962-0061, 109962-0020 for GE13 Engine Excavator Parts original new injector

Engineered for modern high-pressure common rail diesel systems, the Bosch GE13 Series Fuel Injector 109962-0042 (OEM 0445120042) is an original new injection component manufactured according to Bosch OE specifications. Featuring micron-level machining tolerances and precision-matched internal components, it delivers exceptional fuel atomization, precise injection timing, optimized combustion efficiency, reduced particulate emissions, and extended engine service life for demanding commercial and industrial operations.

This injector is widely applied in GM Duramax 6.6L V8 diesel engines (LBZ, LLY, LMM) powering Chevrolet Silverado 2500HD/3500HD, Express, Kodiak C4500/C5500, GMC Sierra, Savana, TopKick, and Hummer H1 vehicles. It is also extensively utilized in diesel engine remanufacturing programs, industrial generator systems, mining and construction machinery, agricultural power systems, and fleet maintenance operations. Extensive cross references—including 0 445 120 042, 0986435521, 0986435521RX, GM 97361355, 97780358, 97780474, Hummer 5745888, Isuzu 8-97361-355-6, AP55521, FJ962, and DE668—simplify global sourcing, interchange verification, and inventory management.

Supporting common rail pressures up to 1600–2200 Bar depending on engine calibration, the injector enables pilot, main, and post injection events for improved fuel economy and enhanced power output. A hardened alloy steel body, wear-resistant needle assembly, and corrosion-resistant coatings ensure long-term durability in heavy-duty service. For reliable installation, new copper washers, O-rings, and sealing components are recommended, along with injector code verification, return flow checks, and adaptation calibration.
