Original Fuel Injector 10R-1265 392-9046 173-9272 304-3637 232-1175 232-1173 382-0709 for 336E C9.3 Original new injector

Engineered for heavy-load diesel combustion environments, the 232-1175 fuel injector group delivers precise fuel metering and consistent atomization for 3408, 3408C, 3408E, 3412, and 3412E engines. This injector supports remanufactured and replacement supply channels, offering core return options that meet the operational needs of diesel repair shops, remanufacturers, fleet operators, and global parts distributors. Fitment for C9.3 applications should be treated as verification required, as public cross-reference data does not consistently confirm compatibility.

The 232-1175 injector cross-references with authorized numbers including CA2321175, 10R-1265, CA10R1265, 20R-0758, CA20R0758, 159-0935, 159-0835, CA1590835, 0R-9420, OR9420, CA0R9420, 174-7527, and 174-7526. It is widely deployed across mining trucks, dozers, loaders, graders, compactors, and underground articulated trucks such as 769D, 771D, 773D, 775D, D9R, D10R, 988F II, 990 II, 631E, 637E, 657E, 24H, 5110B, AD40, AD45, and AE40 II. Key features include heavy-duty durability, stable spray performance, high-temperature operating capability, and multi-number compatibility for streamlined sourcing.

Recommended maintenance includes fuel quality control, filter replacement, injector balance testing, return flow verification, and nozzle spray inspection. Before installation, confirm part number against engine serial number, clean the injector bore, replace sealing components, and follow official torque procedures. Post-installation checks should address leakage, misfire, abnormal smoke, rough running, and diagnostic codes to ensure long service life.
