Perkins original Perkins 293-4067 Fuel Injector for C9 C7 Engine 336D 330 Excavator Spare Part 3879433 20R-8060 new injector original new injector

The Perkins 293-4067 Diesel Common Rail Fuel Injector GP is engineered as a direct OE replacement for Perkins C9 and C9 ACERT industrial diesel engines, delivering precise fuel metering, high-pressure durability, and fine fuel atomization to support stable combustion across demanding operating cycles. Rated for engines producing 205–280 bkW (275–375 bhp) at 1800–2200 rpm, this injector assembly meets China Stage III, EPA Tier 3 equivalent, and EU Stage IIIA equivalent emissions requirements depending on engine configuration, while remaining compatible with modern low-sulfur, low-lubricity diesel fuels.

Designed for heavy-duty performance in Perkins 324D, 325D, 326D, 329D, 330D, 330DL, 336D, and 336DL excavators, the 293-4067 injector integrates wear-resistant coated plungers and robust internal valve components to extend service life, improve fuel economy, and maintain consistent engine output. The assembly cross-references with multiple OE part numbers—10R-4764, 387-9438, 328-2577, 245-3516, and 20R-8060—allowing flexible inventory management for distributors, fleet operators, and service shops servicing Perkins C9-powered construction machinery and related industrial equipment.

Routine maintenance should follow Perkins recommendations: use clean diesel fuel, replace the fuel filter at the prescribed service interval, drain the water separator regularly, and keep the fuel tank free of contamination. When symptoms such as hard starting, rough idle, black or white smoke, misfire, excessive fuel consumption, or power loss appear, technicians should perform fuel pressure testing, return flow testing, cylinder balance testing, injector resistance testing, spray pattern inspection, and ECM fault-code scanning to accurately identify injector-related faults. Spare injectors should be stored in sealed packaging within a clean, dry environment to preserve calibration integrity before installation.
