Engineered specifically for the C12, C10, 3176C, and 3196 diesel engine platforms, this fuel injector delivers OE-level performance and precise fuel metering across heavy-duty on-highway, off-highway, and industrial applications. Multiple cross-reference numbers including 161-1785, 0R-4987, 10R-0967, 116-5414, 212-3462, and 213-3462 allow direct replacement in service, rebuild, and reman exchange operations. Each unit is produced under strict quality controls with flow-balanced output, leak-tested sealing, and verified nozzle spray patterns to ensure consistent combustion and reduced exhaust emissions.

The injector is designed for demanding operating environments such as heavy-duty trucks, construction machinery, mining equipment, and diesel generator sets, where reliable cold starting, stable idle, and optimized fuel atomization are critical. Available in new, remanufactured, or rebuilt configurations with core exchange compatibility, the product supports flexible procurement for truck repair shops, fleet operators, engine rebuilders, reman suppliers, and parts distributors. Export-ready packaging and sealed storage help preserve injector integrity during international shipping and long-term warehousing.

Proper installation requires verification of the engine serial number, arrangement number, original injector part number, injector trim code, and ECM calibration prior to fitting. Routine maintenance including fuel filter replacement, fuel quality control, injector balance testing, cylinder cut-out testing, and ECM fault code reading will help extend service life. Common failure symptoms such as hard starting, rough idle, black or white smoke, misfire, power loss, high fuel consumption, fuel-in-oil, and uneven exhaust temperature should be diagnosed through fuel pressure testing, bench testing, and electrical inspection before injector replacement is confirmed.
