Purpose-built for the rigorous demands of industrial power and heavy equipment operations, the CAT 198-6877 diesel fuel injector is an OEM-grade component engineered exclusively for Caterpillar 3412 series V12 diesel engines. It matches factory specifications for all 3412 variants, including the standard 3412, 3412 DITA, and 3412 E, and offers cross-compatibility with OE number 9W-8895 and replacement component 184-4412. It serves a broad range of sectors spanning construction, mining, marine, agriculture, and industrial power generation.
Constructed from high-grade steel and alloy components, this injector delivers reliable, precision performance in extreme operating conditions. Its multi-hole atomization nozzle features a 155° spray angle and operates at 2000–2500 bar to optimize fuel atomization, support complete combustion, boost engine efficiency, and reduce soot and emissions. The direct-mount design aligns with OEM installation requirements, while precision engineering ensures consistent spray pattern and fuel flow matching factory performance benchmarks.
To support extended service life, the injector follows structured maintenance protocols, with 500-hour inspection intervals, approved solvent cleaning, and seal replacement during routine service. It comes with a 12-month OEM quality warranty, and pre-start calibration of spray pattern and fuel flow is required to prevent leakage and ensure reliable operation. It delivers a cost-effective, durable solution for heavy-duty diesel engine maintenance and repair.
