Perkins original Perkins 0R-1740 Pencil Fuel Injector Nozzle for 3304B 3306B 3306 3304 DISA 3304 Diesel Engine new injector original new injector

The Perkins 0R-1740 diesel injector nozzle is engineered as a direct OEM replacement component for high-pressure fuel injection systems in Perkins industrial diesel engines. Manufactured from high-strength alloy steel and processed through advanced CNC machining, each nozzle delivers precision fuel atomization with optimized spray patterns. The hardened material construction ensures reliable performance under extreme operating pressures, while the specialized surface treatment provides effective corrosion protection against sulfur-containing fuels and moisture contamination, supporting long service life in demanding heavy equipment applications.

This replacement nozzle is fully compatible with Perkins C7, C9, C10, C11, 3126, and ACERT series diesel engines, serving a wide range of machinery including excavators, wheel loaders, bulldozers, articulated dump trucks, motor graders, industrial generators, mining machinery, marine auxiliary equipment, and agricultural equipment. Cross-referenced with part numbers 326-4701 and 10R-7700, it meets strict OEM dimensional tolerances for straightforward installation and consistent fuel delivery.

Routine inspection should include monitoring of engine starting performance, exhaust smoke color, idle stability, and checks for fuel leakage. To maximize service life, operators are advised to use premium diesel fuel, replace fuel filters at recommended intervals, drain water separators frequently, maintain proper fuel pressure, and prevent contamination during servicing. Designed for continuous operation in severe construction and mining environments, this nozzle provides stable injection pressure and dependable performance across global heavy machinery applications.
