Caterpillar original Common Rail Fuel Injector 212-3465 10R-1258  for C10 Diesel Engine,Cross Reference 10R-0961, 212-3462 for Replacement for OEM Parts,  Excavator and Truck original new injector

Built to match Caterpillar’s strict factory requirements, the 10R-1258 diesel fuel injector is an original OEM remanufactured replacement component engineered exclusively for CAT C10 and C12 diesel engine platforms. It cross-references to part number 212-3468 (with format variations 2123468 and 212 3468) for hassle-free part matching, and supports industrial, marine, and generator variants of the two engine series. The injector serves a wide range of heavy-duty sectors including construction, mining, marine applications, power generation, oilfield, and industrial machinery applications.
As a precision fuel metering device, the injector delivers high-pressure atomized fuel into combustion chambers via hydraulically lifted nozzle needles, with electronic timing control to ensure consistent injection accuracy. This design optimizes fuel atomization and combustion efficiency, boosting engine power output while reducing fuel consumption and exhaust emissions for stable, reliable operation. Its industrial-grade hardened steel construction, corrosion-resistant internal parts, and factory-calibrated fuel delivery support extended service life and dependable performance under continuous heavy loads.
For proper installation, technicians must clean the injector bore, replace sealing washers and O-rings, use calibrated torque tools, prime the fuel system, and conduct leak checks post-installation. Routine maintenance requires clean diesel fuel, regular filter replacement, water contamination prevention, fuel pressure monitoring, and periodic injector testing. Backed by a 12-month warranty and global shipping, the component is available for B2B customers across North America, South America, Europe, the Middle East, Africa, Southeast Asia, and Australia.
