Caterpillar original 10R-0968 10R0968 Common Rail Fuel Injector for C10 C12 345B 345C Excavator Replacement for OEM 166-0155 212-3465 212-3466 original new injector

The CAT 10R-0968 is an original remanufactured electronic unit injector designed for the Caterpillar C12 diesel engine, with cross coverage extending to C10, 3176C, and 3196 engine families through numbers such as EX630968, 0R4988, 116-5425, 156-1011, 212-3466, and 716323AT. It delivers high-precision fuel metering and stable atomization, supporting reliable combustion and consistent performance in demanding heavy-duty operating environments encountered in construction, mining, marine, and power generation equipment.

Built for reman exchange programs and global B2B distribution, this injector offers broad OE number compatibility that simplifies procurement for fleet operators, rebuild shops, and spare parts dealers. Its heavy-duty construction is engineered to withstand harsh working conditions while maintaining accurate fuel delivery, reduced smoke output, and improved throttle response. The unit integrates directly into the Caterpillar electronic fuel system, ensuring seamless compatibility with the engine management and diagnostic architecture.

Proper maintenance extends service life and protects injection performance. Operators are advised to replace fuel filters on schedule, drain the water separator regularly, inspect injector wiring, perform cylinder balance and injector cutout tests, monitor return fuel leakage, observe exhaust smoke patterns, and analyze oil for fuel dilution. Preventive replacement during major engine overhauls is recommended. Clean fuel, correct filtration, and timely diagnostics remain essential for long injector reliability across truck, excavator, loader, generator, and marine power applications.
