original 8E-8836 8E 8836Fuel Injector for Engine 3066 3116 Excavator 320 320N Excavator Spare Parts Heavy Duty Accessories original new injector

Built to withstand the rigors of continuous heavy-duty operation, the 8E-8836 diesel fuel injector serves as a direct OEM-equivalent replacement for 3512B series engines. Cross-referenced with 320-4677 and 326-1640, this precision-engineered component supports diesel fuel injection systems deployed across power generation, marine propulsion, mining, construction, and oilfield sectors where reliability is non-negotiable.

Manufactured from high-strength alloy steel with wear-resistant hardened surfaces, the injector delivers precision fuel metering and superior atomization for every combustion cycle. Its high-pressure capability ensures stable performance under extreme injection pressures, while corrosion resistance makes it well-suited for marine and offshore environments. High-temperature endurance supports prolonged heavy-load operation, and the optimized spray pattern reduces fuel consumption and lowers exhaust particulate levels. OEM fitment accuracy enables direct installation without modification or machining.

Applicable engines include the 3512B, 3512B HD, 3512B Generator Set, 3512B Industrial Engine, 3512B Marine Engine, and 3512B Oilfield Engine. The unit is widely deployed in diesel generator sets, cargo vessels, container ships, tug boats, mining trucks, wheel loaders, bulldozers, excavators, industrial compressors, drilling rigs, and pipeline pumping systems. Each injector is shipped as a new component with a 12-month warranty, supporting reliable service in backup power stations, data center generators, hospital emergency systems, and offshore supply vessels worldwide.
