Perkins original Perkins 392-9046 Fuel Injector for C9.3 C9 336E Excavator Replacement for OEM new injector original new injector

The Perkins C9.3 ACERT Common Rail Diesel Fuel Injector 392-9046 3929046 is engineered as a direct OE replacement for Perkins C9.3, C9.3 ACERT, C9.3B, C9.3 Marine, and C9.3 generator-set engine platforms. Manufactured to original equipment specifications, this common rail injector assembly delivers precision fuel metering, high-pressure atomization, and balanced flow performance across the operating range of 250–340 kW / 335–456 hp at 1800–2200 rpm, while supporting U.S. EPA Tier 4 Final, EU Stage V, China Nonroad Stage IV, Japan 2014, and Korea Stage V emission requirements in current configurations.

Built with industrial-grade metallurgy and heavy-duty construction, the injector 392-9046 provides reliable electronic injection compatibility, stable rail pressure response, and long-term fuel economy support. Multiple cross-reference numbers — including 304-3637, 324-5467, 342-5487, 363-0493, 364-8024, 367-4293, 382-0709, 417-3013, 456-3493, 456-3509, 456-3544, 456-3545, 456-3579, 456-3589, 171-9704, 196-1401, 222-5966, 20R-5077, 20R-5078, 20R-5079, 20R-5036, 20R-5073, 20R-5075, and 460-8213 — ensure strong global parts availability and seamless integration into reman, exchange, and aftermarket distribution channels.

Typical applications include Perkins 336E and 336F excavators, large hydraulic excavators, construction machinery, industrial power units, diesel generator sets, marine propulsion and auxiliary engines, mining support equipment, oil and gas power modules, forestry equipment, and material handling machinery. Each injector is sealed in dry export packaging to protect internal components during storage and global shipping, making it an ideal choice for fleet maintenance, engine rebuild programs, and emergency repair supply.
