Engineered for extreme-duty operation, the 386-1752 Fuel Injector Assembly is a precision-manufactured diesel injection component developed for 3500 Series industrial power units. Supplied as an original OEM equivalent with verified cross-reference to 20R-1264, 392-0200, 10R-1284, 11R-0278, and 0R-9944, this injector delivers dependable fuel delivery performance across generator sets, marine propulsion units, mining trucks, quarry machinery, and oilfield power systems where continuous-duty reliability is non-negotiable.
Built with precision-machined internal components and advanced nozzle technology, the 386-1752 injector produces consistent spray patterns, stable atomization, and reliable metering under high-pressure conditions. OEM dimensional accuracy ensures direct-fit compatibility with 3512B, 3508B, 3516B, 3508C, 3512C, and 3516C engine platforms. Operators benefit from improved fuel economy, stable power output, reduced downtime, lower maintenance cost, and superior durability across prime, standby, and heavy industrial applications.
Recommended installation includes engine shutdown, battery disconnection, valve cover removal, seal replacement, torqueing to OEM specification, fuel system priming, and diagnostic verification. Preventive maintenance—high-quality diesel fuel, regular filter replacement, water contamination control, and periodic fuel system cleaning—maximizes service life. Supporting diagnostics include fuel pressure testing, cylinder cut-out testing, injector balance testing, ECM communication checks, and exhaust analysis. Serial number verification is recommended before purchase to confirm correct application fitment.
