Engineered for the CAT 3512B platform and the wider CAT 3500 Series, the Caterpillar 392-0226 Fuel Injector Assembly is a precision diesel fuel injection component compatible with CAT 3508, 3512, 3516 and 3516B engines. Across global diesel supply chains it is identified under OEM numbers 392-0226 / 3920226, remanufactured numbers 20R-1262 and 0R-3539, exchange number 10R-2826, cross references 249-0746 and 192-2817, and legacy number 7E-8836, giving buyers flexible sourcing and cross-verification options.
As a precision-controlled fuel delivery device, the injector holds its internal needle valve closed until calibrated injection pressure is achieved; the nozzle then opens precisely, atomizing high-pressure diesel into a fine mist for complete combustion. This delivers improved fuel atomization, enhanced combustion efficiency, reduced fuel consumption, lower exhaust emissions and stable engine performance. Manufactured from hardened alloy steel with precision machining and wear-resistant internal components, the 392-0226 offers OEM-level operating characteristics and long service life under continuous high-pressure operation.
The injector is widely applied in industrial generator sets, marine engines, mining trucks, drilling equipment, construction machinery and oilfield power systems. Before installation, technicians should clean fuel lines, inspect the injector bore, replace contaminated filters, verify sealing surfaces and prime the fuel system; in service, high-quality diesel and clean filtration help maximize injector life. Hard starting, rough idle, black or white smoke, increased fuel consumption, power loss or misfire indicate the need for inspection or replacement.
