The Perkins 0R-3536 fuel injector nozzle is engineered as a direct OEM replacement component, carrying the authorized OE designation 0R-3536 alongside a comprehensive list of cross-reference numbers including 7N-8518, 325-9351, 213-0611, 236-9310, 326-9315, 212-8475, 204-5922, 249-0713, 293-4072, 328-2582, and 387-9433. This interchangeability ensures seamless fitment across a wide inventory of Perkins-powered equipment without requiring modifications or adapter fittings. Each nozzle is manufactured using CNC grinding technology to achieve micron-level dimensional accuracy, constructed from hardened alloy steel for superior wear resistance, and finished with advanced surface treatment to withstand corrosion in harsh operating environments.

Designed for high-pressure diesel fuel injection systems, the 0R-3536 nozzle is compatible with Perkins C7, C9, 3126, 3126B, 3406E, C11, C13, and 3306 diesel engines. It supports excavators, wheel loaders, bulldozers, motor graders, generator sets, marine propulsion units, industrial pumps, and agricultural machinery. The optimized spray geometry promotes complete fuel atomization and combustion, contributing to improved fuel efficiency, reduced particulate emissions, and stable engine performance across construction, mining, transportation, and power generation applications.

For maintenance, daily inspection of fuel lines and smoke output is recommended, with injector spray quality and fuel pressure evaluated every 500 operating hours. Flow testing and combustion efficiency checks should be performed at 1000-hour intervals, while full injector inspection, seal replacement, and fuel system calibration are advised every 2000 operating hours. The 0R-3536 nozzle is built for continuous heavy-duty operation, delivering long service life and consistent injection performance under demanding industrial conditions.
