Caterpillar original 212-3466 10R-0968 10R-1258 10R-1003 High Pressure Common Rail Injector for C10 C12 345B 345C Excavator Truck original new injector

The Caterpillar CAT C12 C10 3196 diesel fuel injector, OE number 212-3466, is engineered as an original-type replacement component for heavy-duty Caterpillar engine platforms. It is cross-referenced with 10R-0968, 156-1011, 116-5425, EX630968, and 630968, supporting direct installation into the cylinder head injector bore of C12, C10, and 3196 engine configurations used across trucks, construction equipment, excavators, loaders, off-road machinery, and stationary power units.

This electronic unit injector delivers precision fuel metering and fine diesel atomization, supplying the correct fuel quantity at the correct timing to support combustion efficiency, engine response, power output, and emissions performance. Its heavy-duty construction is developed for Caterpillar diesel engines operating with modern low-sulfur, low-lubricity fuels, making it suitable for professional repair shops, diesel engine rebuilders, heavy equipment service teams, fleet maintenance departments, mining contractors, construction contractors, trucking operators, and industrial engine maintenance companies.

Proper service practices extend injector life and engine reliability. Operators should use clean diesel fuel, replace fuel filters on schedule, drain the water separator regularly, and clean the fuel tank when contamination is found. Engine oil, combustion, and air intake condition should be maintained to prevent carbon deposits. The injector wiring harness must be inspected for oil intrusion, heat damage, broken insulation, corrosion, and loose terminals, and stored injectors should remain sealed, clean, dry, and protected from dust, impact, and moisture.
