Caterpillar original 10R-3264 Fuel Injector Overhaul Repair Kit 10R-3263 Replacement for 253-0617, Fits C15 C18 C27 C32 3406E Engine, Excavator Truck Parts, 20R-1914 original new injector

Engineered for Caterpillar C15 and C15 ACERT heavy-duty diesel engines, the 10R-3264 fuel injector is a precision-built electronic unit injector designed to meet OEM-level specifications. Supplied under part numbers 10R-3264 / 10R3264 and cross-referenced with 217-2570, 2172570, 328-2574, and 3282574, this diesel injector assembly serves a wide range of applications, including heavy-duty highway trucks, generator sets, construction equipment, mining machinery, industrial power units, marine propulsion engines, and agricultural power systems.

Inside the fuel system, the injector operates as an electronically controlled fuel metering device: pressurized diesel enters through the high-pressure fuel passage, the ECM triggers the solenoid valve, the needle lifts, and fuel is atomized through precision nozzle holes into the combustion chamber. This process delivers improved fuel atomization, higher combustion efficiency, reduced fuel consumption, lower exhaust emissions, increased power output, sharper throttle response, and stable idle performance under heavy-load conditions.

Manufactured to OEM-level standards, the 10R-3264 offers high-pressure resistance, long service life, and proven durability in harsh operating environments, helping fleets reduce maintenance costs. For best results, always install with new seals and O-rings, verify the injector calibration code where applicable, keep the fuel system clean, and perform injector balance testing after installation. Routine care—OEM-quality fuel filters, clean fuel, and periodic injector performance testing—helps prevent common issues such as hard starting, rough idle, excessive smoke, power loss, increased fuel consumption, and emission compliance failure.
