Engineered as a precision-critical component for the 3412 series V12 diesel engine platform, the 222-5967 fuel injector delivers OEM-grade performance across demanding industrial, marine, mining, and power generation environments. This direct injection nozzle assembly is a verified replacement for OE 222-5967 and interchanges with cross reference numbers 0R-8682, 10R-0955, 170-5187, and 212-3467, ensuring accurate fitment for 3412, 3412B, and 3412C engine configurations used in generator sets, marine propulsion units, mining haul trucks, and heavy-duty industrial power plants.

Built from high-strength alloy materials with a corrosion-resistant finish, the injector is designed for continuous heavy-load operation and offshore duty. Key engineering features include precision fuel metering for accurate delivery every combustion cycle, enhanced atomization through ultra-fine spray patterns, high-temperature resistance, and hardened internal wear components that extend service life. These characteristics support cleaner combustion, reduced emissions, and stable fuel pressure under prime and standby power duty cycles typical of drilling platforms, compression stations, and emergency backup systems.

Recommended maintenance includes regular fuel filter replacement, use of clean diesel fuel, fuel pressure inspection, exhaust smoke monitoring, and scheduled injector testing to prevent black or white smoke, hard starting, misfire, rough idle, and reduced power. Installation requires OE number verification, clean injector bores, new sealing washers, correct torque specifications, fuel system bleeding, leak inspection, and post-installation performance testing to secure reliable long-term operation.
