original 386-1767 Common Rail Fuel Injector for 3508B 3512B Construction Engine new injector original new injector

Engineered exclusively for the 3512B platform, fuel injector 386-1767 is purpose-built to match the V12 architecture and electronic unit injection parameters of the 3512B series. Direct-fit compatibility extends across the related engine families, including 3512, 3512C, 3516B, 3516C, 3508, 3508B, 3508C, 3524, and 3524B, enabling service operations on a wide range of heavy industrial and marine power units without modification.

The multi-hole nozzle design delivers precise fuel atomization directly into the combustion chamber at controlled injection intervals, supporting stable power output and consistent engine responsiveness under continuous-duty conditions. Built to OEM manufacturing standards, the injector assembly features high temperature resistance, corrosion-resistant materials, and high precision fuel metering to ensure extended service life in demanding applications such as generator sets, marine propulsion engines, mining equipment, and oilfield power units.

Proper installation requires cleaning the cylinder head injector bore, fitting new sealing components, lubricating O-rings, torquing to specifications, bleeding the fuel system, and verifying fuel pressure before operational testing. For sustained performance, operators should use OEM fuel filters, supply clean diesel fuel, monitor fuel pressure and injector balance rates, and conduct periodic bench testing to identify worn assemblies before failure occurs.
