Caterpillar original 224-9090 Fuel Diesel Injector Pump for Caterpillar C3600, Replacement for OEM 10R-1252, 111-3718, 20R-4179, for Excavator and Generator Set Construction original new injector

Precision-engineered as a direct-fit, OEM-equivalent component for Caterpillar 3500 Series diesel engines, the 224-9090 Electronic Unit Injector is compatible with 3512A, 3512B, 3516 and 3508 engine models for targeted use cases. It serves mining trucks, marine propulsion systems, generator sets, oilfield pumping equipment, stationary industrial power units and emergency backup power installations across global industrial markets. Cross-reference suitability shall be verified via engine serial number, arrangement number and injector calibration code prior to purchase to ensure proper matching.

Operating as a high-pressure precision fuel metering device, the injector follows electronic control signals to adjust injection timing, opens its calibrated needle valve to atomize diesel into fine particles, and delivers optimized air-fuel mixing for complete combustion. This design brings measurable operational benefits including precise fuel delivery, improved combustion efficiency, reduced fuel consumption, lower exhaust emissions, enhanced engine response, stable idle performance, higher power output and extended engine service life under heavy-duty operating conditions.

Every 224-9090 injector undergoes strict quality inspection and testing before delivery, with hardened internal components, corrosion-resistant materials, industrial-grade sealing technology and OEM-standard calibration to ensure reliable performance. It is shipped in individual protective packaging with a 12-month warranty, and installation shall follow Caterpillar official service procedures, with seal replacement, fuel line inspection and post-installation leak testing recommended to maintain long-term stable operation.
