Caterpillar original  Common Rail Diesel Fuel Injector 20R-1276 392-0214 20R1276 for 3508B 3512B 3516B 3508 3512 3516 C3500 Engine Construction Excavator original new injector

Engineered for the demanding conditions of CAT 3500 series platforms, the Caterpillar 3512B Fuel Injector 392-0214 delivers high-precision fuel metering and superior atomization through a multi-hole precision-machined nozzle. Each unit is calibrated with engine-specific trim codes, ensuring accurate fuel delivery, consistent spray patterns, and seamless communication with the engine control module across CAT 3512, 3512B, 3512C, 3508B, 3508C, 3516B, 3516C, and CAT 3524 applications.

Manufactured from premium hardened steel alloys with a corrosion-resistant design, this injector withstands high injection pressures exceeding 2000 bar, thermal stress, and continuous heavy-duty operation in marine, mining, oil and gas, power generation, construction, and rail environments. The direct OEM compatibility allows it to serve as a true replacement for Caterpillar original equipment, while the wide interchange coverage with part numbers such as 20R-1275, 0R-8892, 0R-8690, 386-1766, 250-1314, 229-0193, 150-4456, 126-7995, 132-0204, and 114-6469 simplifies inventory and part identification.

For optimal performance, depressurize the fuel system before installation, apply OEM-approved anti-seize on threads, torque to Caterpillar factory specifications, and verify that the injector trim code is recognized by the ECU. Routine inspection of injector tips, regular fuel filter replacement, and use of clean diesel with sub-10 micron filtration will maximize service life and maintain combustion efficiency in continuous industrial operation.
