Caterpillar original common rail fuel injector 10R-0725 212-3464 212-3463 10R-9235 10R-1264 0R-4987 10R-1814 208-9160 10R-0963 for 3176C 3196 C10 C12 engine original new injector

Engineered for heavy-duty diesel performance, the 10R-0725 / 10R0725 remanufactured fuel injector delivers precision fuel metering, controlled spray pattern, stable atomization, and high-pressure durability for Caterpillar C10, C12, 3176, 3176C, and 3196 engines. The unit supports cylinder-specific fuel delivery, combustion stability, and low-emission operation, helping restore engine power, reduce rough idle, improve fuel economy, and minimize exhaust smoke across truck, industrial, and marine duty cycles. New sealing components lower leakage risk, while nozzle flow matching maintains balanced cylinder performance for long service life.

This injector is compatible with a broad range of on-highway trucks, including Freightliner Condor, Sterling Truck Condor, Peterbilt 385, Peterbilt 320, Peterbilt 357, Crane Carrier Low Entry, International Harvester 5600i, Spartan Motors Gladiator, Sterling Truck L9500, Sterling Truck A9500, Freightliner Century Class CST112, Freightliner FLD112, Western Star 4900SA, and Western Star 4900FA. It is also approved for Caterpillar 3176C and 3196 industrial engine units and Caterpillar 3196 marine engine applications. Authorized cross references include 212-3464, 212-3462, 10R-0967, 166-0153, 161-1785, 116-5414, CH-12082, EX630725, CA10R0725, CA2123464, and CA1660153. All vehicle and equipment fitments must be confirmed by VIN, engine serial number, original injector number, and ECM calibration before installation.

Before installation, verify injector part number, engine serial number, old injector number, injector trim code, and engine configuration. Clean the injector bore, fuel lines, and sealing surfaces, replace O-rings, washers, and injector seals, and lubricate O-rings with clean engine oil. Inspect the bore for carbon or scoring, check fuel lines for contamination or leakage, and confirm connector condition. Use only Caterpillar-specified torque values, prime the fuel system before starting, and perform leakage, misfire, smoke, cylinder cut-out, fuel pressure, and load testing after installation. Store injectors in sealed, dry, and clean packaging to preserve remanufactured quality.
