Original Diesel Injector 232-1173 382-0709 10R-1265 173-9272 304-3637 392-9046 198-7912 for 336E C9.3 original new injector

Engineered for demanding heavy-duty diesel applications, the 198-7912 Fuel Injector is a precision-manufactured fuel injection assembly designed specifically for the C9.3 engine platform, including C9.3 ACERT, C9.3 Industrial, C9.3 Generator, and C9.3 Marine variants. Identified by primary OE reference 198-7912 (1987912, CA1987912) and cross-compatible with 232-1173 (2321173, CA2321173) and supplier reference 4CR-01974 (4CR01974), this injector delivers OEM-grade fuel atomization and pressure performance for global equipment fleets.

Each unit is produced from hardened alloy steel with precision-ground nozzle assemblies, high-pressure resistant bodies, and heat-treated internal components. OEM fuel flow calibration and a strict flow-matching process ensure consistent injection across all cylinders, while 100% leakage inspection and corrosion protection guarantee long-term reliability. Operators benefit from improved combustion efficiency, lower fuel consumption, reduced exhaust emissions, increased engine power output, and superior cold-start performance under harsh operating conditions.

The 198-7912 injector supports excavators, wheel loaders, backhoe loaders, mining trucks, drilling rigs, generator sets, marine auxiliary engines, pump drives, and industrial compressors across construction, mining, power generation, marine, and oil & gas sectors. Installation requires cleaning the injector bore, replacing sealing washers and O-rings, torqueing to OEM specification, bleeding the fuel system, and verifying injector balance. Use clean diesel fuel and replace filters regularly to maximize service life and protect the diesel fuel injection system.
