original 155-1819 Diesel Engine Fuel Injector Assembly for 336E C9.3 Common Rail new injector original new injector

The Fuel Injector 155-1819 is an OEM-specification diesel fuel injection component engineered exclusively for the C9.3 engine family, including the C9.3, C9.3B, C9.3 ACERT, Industrial C9.3, and Power Unit C9.3 variants. Built to factory tolerances, this injector delivers high-pressure fuel delivery with ECM-controlled injection timing and duration, ensuring accurate fuel atomization, optimized combustion efficiency, and consistent engine performance across demanding operating conditions. Direct-fitment design guarantees seamless compatibility without the need for modifications, restoring original power output and emission compliance.

Manufactured using high-precision internal components, hardened wear surfaces, and advanced nozzle technology, the 155-1819 fuel injector provides excellent durability and long service life even under heavy-duty industrial loads. Each assembly is engineered to meet strict OEM quality standards, delivering stable injection performance, reduced emissions, and lower maintenance requirements. The injector integrates seamlessly with the electronic unit injector fuel management system, supporting precise metering of fuel for applications ranging from hydraulic excavators and wheel loaders to diesel generator sets and industrial power plants.

Designed for construction, mining, marine, agricultural, and power generation equipment, the 155-1819 injector is a reliable replacement assembly for C9.3 series engines operating in hydraulic excavators, motor graders, mining trucks, marine auxiliary engines, and emergency backup systems. Installation should follow OEM specifications, including priming the fuel system, performing a leak test, and verifying engine operation after assembly. Regular use of high-quality diesel fuel, periodic injector testing, and timely replacement of fuel filters and sealing components will help maintain peak injection performance and extend service intervals in heavy equipment operations.
