Caterpillar original  162-0212 Fuel Injector for 3114 3116 3126 Engine Replacement for OEM 127-8216 107-7732 4P2995 0R-8475  original new injector

The CAT 3116 3126 diesel fuel injector, main OE number 162-0212 / 1620212 / CA1620212, is an industrial-grade unit injector assembly engineered as a direct replacement component for Caterpillar 3116 and 3126 diesel engines. It is widely fitted to marine propulsion systems, industrial generator sets, construction machinery, commercial trucks, excavators, loaders, and a broad range of off-highway diesel equipment operating in demanding environments. Buyers are advised to confirm the engine model, engine serial number, fuel system configuration, and existing injector part number prior to purchase to ensure correct fitment.

This injector cross-references with multiple authorized replacement numbers including 0R-8463, CA0R8463, 127-8230, CA1278230, 7E-6193, 127-8216, 127-8228, 107-1231, 6I-3669, 0R-4368, and 0R-3762, allowing flexible interchangeability across different CAT 3116 and 3126 engine applications. Manufactured to heavy duty industrial standards, the assembly delivers consistent fuel atomization, stable injection pressure, and reliable metering performance required for continuous-duty operation. It serves as a cost-effective aftermarket solution for fleet operators, marine engineers, and industrial equipment maintenance programs.

To maintain proper engine balance and consistent combustion performance, it is recommended to replace the complete set of injectors when flow output or atomization characteristics may differ between old and new units. Routine inspection of injector condition, sealing integrity, and return line leakage is advised to maximize service life.
