CAT-900 Professional CAT HEUI Injector and 320D Fuel Pump Test System
The CAT-900 is a high-precision diagnostic platform specifically engineered for the maintenance of Caterpillar electronic control systems. This versatile system integrates the testing of HEUI (Hydraulic Electronic Unit Injectors) found in CAT 3126, C7, and C9 engines, as well as the specialized Caterpillar 320D high-pressure common rail pumps. The CAT-900 allows technicians to simulate real-world operating conditions by controlling injection frequency, pulse width, and oil pressure. With a high-definition touch interface and built-in standard test plans, it provides an efficient and accurate solution for diagnosing fuel delivery issues, ensuring Caterpillar machinery operates at peak performance and meets emission standards.
