original Replacement Diesel Common Rail Fuel Injector 116-3526 0R-8786 for Engine Cross Reference 138-8756, for Sprayer Excavator Truck, also Compatible with 20R-0760 original new injector

Built for demanding 3412 power platforms, the 116-3526 fuel injector is an OEM-equivalent diesel injection component for industrial, marine and power-generation service. It is suitable for 3412, 3412B, 3412C and 3412 DITA engines, including marine, generator and industrial configurations. Cross references include 1163526, 0R-8688, 0R-8783, 4P-9830 and 7W-7032, supporting accurate part identification for distributors, repair workshops and fleet maintenance teams.

Within the fuel system, high-pressure diesel enters the injector body and opens the internal needle valve at its calibrated pressure. The injector then delivers metered fuel as finely atomized droplets, while excess fuel returns through the system. Precision fuel metering, OEM-level calibration, durable nozzle construction and industrial-grade materials support efficient combustion, stable idling, reliable power output and reduced fuel consumption. Fine atomization can also help lower exhaust emissions, while the heavy-duty design is intended for long service life and reduced maintenance requirements.

Typical installations include diesel generator sets, marine propulsion systems, offshore power units, mining equipment, industrial pump drives, oilfield drilling systems and emergency power systems. Before installation, clean the injector bore, verify fuel-system cleanliness and replace damaged sealing components; after installation, prime the system and perform a leak test. Regular fuel-filter replacement, high-quality diesel and water-contamination control help maintain performance. The injector is supplied with a 12-month warranty, with custom packaging and worldwide shipping available.
