The Caterpillar CAT C12 C10 Fuel Injector 212-3465 is an industrial-grade Electronic Unit Injector engineered for accurate fuel delivery and stable spray atomization across heavy-duty diesel applications. Designed specifically for Caterpillar C12, C10, 3176, 3176C, and 3196 diesel engines, this injector supports electronic injection control, controlled combustion, smoother engine operation, and reduced fuel-related performance issues in demanding operating environments.

Cross-referenced with 10R-0961, 0R-7549, 166-0155, 116-5426, EX630961, 630961, CA2123465, CA10R0961, CA0R7549, and CA1660155, the 212-3465 injector serves as a direct OE replacement for Caterpillar Challenger 65E, 75D, 75E, 85D, 85E, and 95E tractors, Caterpillar Combine 480, trucks, mining equipment, construction fleets, generator maintenance programs, and industrial power systems. The reman process includes critical component lapping, new nozzle replacement, solenoid replacement, spring and shim replacement, check-ball replacement, and 100% O-ring replacement.

Built for compatibility with modern low-sulfur, low-lubricity fuels, this injector delivers stable performance throughout extended service intervals. Recommended maintenance includes the use of clean diesel fuel, scheduled fuel filter replacement, water separator draining, harness inspection, and leakage checks. For reman or exchange units, professional testing should incorporate flow testing, solenoid response testing, resistance testing, leak testing, and spray pattern inspection to ensure reliable operation.
