Caterpillar original 0R-1759 Fuel Injector Assembly for C3500 3512 3516 3508 Gen Set Engine Replacement for OEM original new injector

The Caterpillar 0R-1759 fuel injector is a precision-engineered component designed for the CAT 3512A diesel engine platform. As a genuine OEM replacement part, it delivers accurate fuel metering through a controlled multi-stage injection process, beginning with fuel delivery into the injector body, followed by internal pressurization, timed injection events, and high-pressure atomization through precision nozzle holes. This ensures complete fuel-air mixing for efficient combustion and reliable power output across demanding operating cycles.

This injector assembly is compatible with CAT 3512A, CAT 3512, CAT 3512B, and CAT 3512C engines, as well as related CAT 3500 Series platforms including the CAT 3508 and CAT 3516. It carries the cross reference number 326-4706, allowing for straightforward identification and replacement. Each unit is manufactured to original factory specifications, ensuring proper fitment, consistent spray patterns, and stable fuel pressure performance under heavy-duty industrial loads.

The 0R-1759 injector is widely deployed across CAT generator sets, marine propulsion systems, offshore platforms, oilfield power units, mining trucks, mining power stations, industrial pump drives, emergency backup power systems, data center generator plants, utility power facilities, hospital backup generators, airport power systems, and telecommunications power stations. Operators and maintenance teams rely on this genuine CAT injector to maintain engine efficiency, reduce unplanned downtime, and support long service intervals in mission-critical power generation and industrial applications.
