Caterpillar original Caterpillar 10R-1305 diesel fuel injector common rail for 3406E C12 C15 engine new injector original new injector

Engineered for demanding industrial applications, the 10R-1305 Electronic Unit Injector delivers OEM-level manufacturing precision for C11 series diesel engines. This remanufactured fuel injector is a direct replacement solution for C11, C11 ACERT, C11 Industrial Power Unit, C11 Generator Set Engine, C11 Marine Propulsion Engine, and C11 On-Highway Truck Engine platforms. Cross-referenced under 249-0713 and 387-9433, the injector integrates seamlessly into existing fuel systems, ensuring interchangeability for global aftermarket supply and fleet maintenance operations.

The 10R-1305 features a high-pressure fuel delivery system with precise fuel metering and superior atomization, enabling enhanced combustion efficiency and improved horsepower output. Operators benefit from low fuel consumption, reduced exhaust and particulate emissions, and better cold start performance across variable ambient conditions. Constructed for industrial-grade durability, the injector maintains excellent reliability in harsh environments—including mining sites, quarries, marine vessels, prime power stations, and agricultural irrigation units—while contributing to long service life and increased fuel economy across the powertrain.

Application coverage extends to excavators, wheel loaders, dozers, road machinery, mining trucks, material handling systems, diesel generator sets, emergency backup systems, commercial vessels, and heavy-duty fleet vehicles. Recommended maintenance includes using high-quality diesel fuel, regular fuel filter replacement, and ECM fault code monitoring. During installation, verify ECM compatibility, replace seals and O-rings, and follow service manual torque specifications. Diagnostic support includes injector balance testing, fuel pressure verification, solenoid resistance measurement, leak-down testing, and cylinder contribution testing.
