Caterpillar original C15 C18 C27 C32 Engine Series Fuel Injector 10R-3264, 20R-2284, 20R-1914, 10R-1273 Replacement for OEM Parts for Excavator and Truck original new injector

For sourcing teams and maintenance operators managing Caterpillar C15-powered assets, the 10R-3264 electronic unit fuel injector is a specification-compliant replacement for diesel fuel systems. It fits all C15 and C15 ACERT engine variants, including heavy-duty truck, industrial power, generator set, and marine propulsion configurations, and cross-references to 217-2570 (2172570) and 328-2574 (3282574). Cross-reference applicability varies by engine arrangement, emissions setup, serial number, and regional specification, so ESN verification is recommended before ordering.

Manufactured to OEM-level quality standards, the 10R-3264 delivers precision fuel metering and consistent high-pressure delivery for optimized combustion. Its precision-machined nozzle produces fine atomized fuel mist, boosting combustion efficiency, cutting fuel consumption and emissions, increasing horsepower, improving throttle response, and stabilizing idle. The industrial-grade design resists harsh operating conditions, maintains reliability under sustained heavy loads, and extends service life to reduce long-term maintenance costs.

Installation must follow official Caterpillar service manual protocols: use new seals and O-rings, verify calibration codes where applicable, and conduct injector balance testing post-installation. Routine maintenance requires OEM-quality fuel filters, clean fuel, regular fuel pressure monitoring, and periodic performance testing to prevent common issues like hard starts, rough idle, and reduced power. It suits global on-highway heavy-duty truck, construction, mining, power generation, marine, industrial, and agricultural applications.
