original 173-4059 20R-0760 174-7528 Diesel Common Rail Injector for 3412 3408 3412E Engine 3512B 5110B 3126B Equipment new injector original new injector

Engineered specifically for the 3412 engine platform, this fuel injector delivers precise fuel metering and consistent atomization across every combustion cycle. The injector assembly is built to OEM specifications, ensuring direct compatibility with 3412, 3412B, and 3412C engine configurations used in generator sets, marine propulsion units, mining trucks, oilfield equipment, and heavy-duty industrial machinery. Optimized injector geometry promotes complete fuel atomization, supporting improved combustion efficiency, enhanced power output, and reduced exhaust emissions under variable load conditions.

Manufactured as a genuine-style OEM replacement component, the injector maintains stable fuel delivery at high combustion pressures and provides reliable cold-start performance in demanding operating environments. Precision-machined internal components and high-grade sealing materials contribute to extended service life, lower fuel consumption, and stable idle operation. Each unit is designed to match the original injector flow characteristics, allowing for straightforward installation without requiring additional calibration or engine control modifications on the 3412 series.

Proper installation following service manual procedures helps maximize injector performance and longevity. Operators are advised to use clean diesel fuel, replace fuel filters at recommended intervals, inspect fuel supply lines for damage, and torque injector mounting hardware using calibrated tools. Routine monitoring of fuel pressure and exhaust condition supports preventive maintenance practices. The injector is supplied in standard export packaging and is ready for deployment across power generation, marine, mining, oilfield, and general industrial engine applications worldwide.
