original 162-8809 Diesel Fuel Injector 132-0202 229-0194 250-306 Replacement for 3508 3512 3516 Engine new injector original new injector

The 162-8809 fuel injector is specifically engineered for 3512B, 3512C, 3516B, and 3516C diesel engines, ensuring precise compatibility with the 3500 Series platform. Manufactured to OEM-level standards, this injector delivers excellent fuel atomization and high pressure endurance, meeting the demanding requirements of heavy duty diesel applications. The hardened alloy steel construction provides long operating lifespan and corrosion resistance in harsh operating environments such as marine, oilfield, and mining sectors. Every unit is 100% flow and leak tested to ensure consistent performance, optimized fuel efficiency, and reduced emissions across continuous duty cycles.

As a direct replacement for OEM part number 162-8809, this injector also cross-references with 0R-8682, 10R-7224, CAT1628809, and -162-8809, making it a versatile solution for maintenance and overhaul operations. It is widely applied in diesel generator sets, marine propulsion systems, offshore power modules, mining trucks, heavy excavators, oilfield drilling rigs, industrial compressors, and emergency backup power stations. The precision-machined nozzle and high pressure direct injection design support stable combustion, lower fuel consumption, and reliable cold-start performance in commercial vessels, tugboats, offshore support vessels, and pump drive systems operating in remote and challenging conditions.

To maintain peak injector performance, operators should use clean diesel fuel, replace fuel filters at regular intervals, and avoid water contamination in the fuel supply. Routine diagnostic procedures such as fuel pressure testing, cylinder balance testing, injector return flow testing, leakage testing, spray pattern inspection, ECU diagnostic scanning, and exhaust analysis are recommended in accordance with maintenance schedules. Following these practices helps reduce lifecycle maintenance costs, extends engine service intervals, and ensures dependable operation of 3512B and related 3500 Series engines across industrial, marine, and power generation applications.
