original 10R-1256 223-5327 229-8842 10R-0967 10R-0961 Fuel Engine Injection System for C12 C10 new injector original new injector

Engineered specifically for C10 and C12 diesel platforms, this remanufactured fuel injector is built around the authorized OE numbers 10R-1256 and 223-5327, with verified interchange coverage for 212-3464, 10R-0725, CH12082, 0R-8773, 229-5918, 212-3463, 229-8842, 10R-1003, and 20R-0055. It is also validated against the broader 3176, 3196, and 3176C engine families, ensuring correct fitment, calibration baseline, and injector geometry for these specific power units used in heavy-duty trucks, construction machinery, mining equipment, generator sets, and marine auxiliary installations.

The injector assembly delivers a controlled fuel quantity, accurate injection timing, and a stable spray pattern into the combustion chamber, supporting combustion balance across all cylinders. It helps reduce rough idle, improve throttle response, lower visible smoke, and protect pistons, valves, cylinder liners, and turbocharger systems. Remanufactured with coated plungers, current engineering updates, and validated for modern low-sulfur and low-lubricity diesel fuels, it meets the operational demands of professional engine repair, rebuild, and fleet maintenance programs.

For long service life, clean fuel and correct filtration are essential, including regular fuel filter service, water separator drainage, and inspection of the fuel return system. During installation, replace all injector seals, O-rings, and washers, apply service manual torque specifications, and perform injector trim or coding where the engine management requires it. Post-installation checks should include leak-down inspection, idle quality verification, exhaust smoke evaluation, fuel pressure confirmation, and diagnostic scan review.
