Perkins original Perkins 20R-0759 Diesel Engine Fuel Injector 10R-1267 2C0273 174-7528 20R-4148 173-4061 for Perkins 3412 3408 original new injector

The Perkins 3412 fuel injector 20R-0759 is engineered as a direct OEM replacement for the original 7W-7118 unit used across the Perkins 3412 diesel engine platform. Designed for the demanding operating conditions of V12, 4-stroke industrial engines, this remanufactured injector is built with high-grade, corrosion-resistant steel and produced under ISO 9001 and CE certified processes to ensure consistent quality and long service life in heavy-duty applications.

Featuring a precision-machined multi-hole nozzle with a 150°–160° spray angle and an operating pressure range of 2000–2200 bar, the injector delivers high fuel atomization for improved combustion efficiency, lower particulate emissions, and stable engine performance. It is fully compatible with cross numbers 331-9752 and 20R0759, making it a reliable drop-in solution for mining trucks, bulldozers, excavators, marine engines, industrial generators, and pumps, including equipment such as the Perkins 777D Dump Truck, Perkins D11T Bulldozer, Perkins 992K Wheel Loader, and Perkins 3512B Industrial Pump.

Installation requires a calibrated torque wrench set to 25–35 Nm, with cleaned injector seats, clean fuel lines, and light oil on the threads prior to fitting. Routine inspection of the injector nozzle every 500 hours helps maintain spray pattern integrity, fuel pressure consistency, and reliable opening response. For distributors, remanufacturing suppliers, and Perkins service centers managing large industrial fleets, the 20R-0759 offers a durable, serviceable, and cost-effective replacement option that supports reduced downtime and extended engine life.
