198-6605 Fuel Injector is a hydraulic electronic unit injector (HEUI) designed for selected Ca-terpillar 3126B, 3126E and C7 marine 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 medium-duty commercial trucks, marine equipment and industrial applications powered by compatible 3126B, 3126E and C7 marine diesel engines. Please verify the original part number, engine serial number, arrangement number and equipment model before ordering.
198-6605 HEUI Fuel Injector is designed as a direct-fit replacement for the correct engine configuration. Its commonly associated Cat Reman reference is 10R-0781, with 197-7107, 199-6065, 222-5966 and EX630781 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.
