original 392-0217 Diesel Fuel Injector Assembly Construction Machinery Parts Compatible with 3512 3508 3520 new injector original new injector

Engineered as a direct-fit replacement, the 392-0217 fuel injector is purpose-built for the 3512B engine platform, with full cross-reference compatibility extending to 3508B and 3516B series. This injector carries authorized OE numbers 20R-1278, 10R-3255, 386-1769, 230-9457, 11R-0286, 10R-7220, 10R-7220B, and 0R-3539, ensuring verified interchangeability across multiple engine families. Both OEM and remanufactured options are available, meeting or exceeding original tolerances for demanding B2B applications.

The injector incorporates precision-engineered nozzle technology that delivers consistent atomization, reduces carbon buildup, and supports cleaner combustion. High-pressure resistance rated up to 160 MPa, wear-resistant alloy steel construction, and specialized coatings provide durability under continuous industrial operation. With injection accuracy of ±0.5% and a flow rate between 300-400 cc/min, this component enhances fuel efficiency, lowers unburned hydrocarbon emissions, and delivers stable thermal output for power generation, marine, mining, and oilfield installations worldwide.

Routine inspection every 500 operating hours, including checks for fuel leakage at the injector body and nozzle, is recommended. Operators should use high-grade ISO-conforming diesel, replace fuel filters regularly, and perform spray pattern and flow testing on authorized benches during overhauls. Injector seals and copper washers must be replaced with approved parts, and hold-down torque should follow service manual specifications, typically 35-45 Nm.
