178-0198 HEUI Fuel Injector for Ca-terpillar 3126B and 3126E Diesel Engines
178-0198 Fuel Injector is a hydraulic electronic unit injector (HEUI) designed for selected Ca-terpillar 3126B and 3126E diesel engine applications. It uses high-pressure engine oil and electronic control to accurately pressurize, meter and inject fuel, supporting stable combustion, efficient fuel use and reliable engine performance.
It is suitable for selected 322C, 322C FM, 325C, 325C FM and 325C L excavators, M325C MH material handlers, IT62G II integrated tool carriers, 950G II and 962G II wheel loaders, 570B and 580B wheel harvesters, 460, 465 and 470 combines, SPP101 pumpers, commercial trucks and industrial equipment. Please verify the original part number, engine serial number, arrangement number and equipment model before ordering.
178-0198 HEUI Fuel Injector is designed as a direct-fit replacement for the correct engine configuration. Its commonly associated Cat Reman reference is 10R-0782, with 177-4754, 178-0199 and 205-1285 frequently listed as replacement or cross-reference numbers. Professional installation and any required injector setup or ECM calibration should follow the applicable engine service manual.
.Manufactured with wear-resistant precision components and a reliable sealing structure, this injector withstands continuous vibration and demanding working conditions. It helps address hard starting, unstable idle, power loss, excessive fuel consumption and black smoke.
Every Fuel Injector we supply undergoes professional bench testing. Injection quantity, spray pattern, sealing performance and operating stability are inspected to ensure reliable fuel delivery and consistent engine performance.
