Caterpillar original Caterpillar 874-822 fuel injector replacement for OEM diesel engine spare part new injector original new injector

The Caterpillar CAT C10 C11 C12 C13 fuel injector 874-822 is engineered as a direct OEM specification replacement for demanding industrial diesel applications. Compatible with CAT C10, C11, C12, C13, 3176, and 3196 engines, this injector assembly serves excavators, loaders, mining trucks, generators, marine propulsion engines, and heavy construction machinery. Authorized cross reference numbers include 1OR-1268, 0R-1268, 127-8213, and 127-8216, ensuring precise identification and reliable interchangeability for global fleet operators and aftermarket distributors.

Manufactured with precision nozzle technology and high pressure fuel atomization capability, the 874-822 injector delivers consistent fuel metering and optimized spray patterns. Corrosion resistant materials and heavy-duty construction provide long service life under extreme operating conditions, while improving cold start performance, increasing engine power output, and reducing both fuel consumption and exhaust emissions. The direct fit installation design allows seamless integration with existing fuel systems without modification, supporting extended engine service life across industrial, marine, and power generation environments.

Proper maintenance of the 874-822 injector assembly requires the use of clean diesel fuel, regular fuel filter replacement, and prevention of water contamination. Periodic injector testing, exhaust smoke monitoring, and fuel consumption trend analysis are recommended to identify performance deviations early. Before installation, the fuel system should be cleaned, sealing washers replaced, and fuel lines inspected. Verification of injector coding, ECU calibration when required, and fuel pressure testing ensure correct operation and sustained reliability throughout the service cycle.
