Caterpillar original 10R-1268 Common Rail Fuel Injector Replacement for OEM C10 C12 3176 3196 Engine Parts Truck Excavator original new injector

The Caterpillar 10R-1268 diesel fuel injector is engineered as an OEM reman replacement for CAT C10, C12, C12 ACERT, and 3176B diesel engines deployed across construction, mining, marine, oil and gas, and power generation sectors. Built from heat treated alloy steel and fitted with a multi hole precision nozzle, this electronic unit injector delivers high pressure direct injection with consistent atomization and accurate fuel metering under heavy duty industrial workloads.

Compatible with CAT 320, 325, 345B, and 365B excavators, 950, 966, and 980 wheel loaders, mining trucks and excavators, marine propulsion systems, drilling rigs, pumping stations, and generator sets, the 10R-1268 carries cross references including 236-4086, 203-7685, 170-5252, 20R-0056, and 350-7555. The unit conforms to OEM specification standards and provides industrial grade pressure resistance for reliable operation in demanding field conditions.

Routine maintenance supports long injector service life. Recommended intervals include fuel filter replacement every 250 hours, injector inspection every 500 hours, fuel pressure testing every 1000 hours, and injector calibration every 2000 hours. Operators monitoring for hard starting, black smoke, white smoke, or loss of power can attribute these symptoms to worn nozzles, fuel contamination, poor atomization, injector leakage, or low injection pressure, all of which the 10R-1268 is designed to address through OEM level compatibility and precision manufacturing.
