Description
The PAI Industries 390082X is a remanufactured (exchange) fuel injector assembly for Caterpillar C9 diesel engines, replacing Caterpillar 328-2574 and its related OEM service numbers including 10R-7222, 254-4339, 267-3360, and 293-4072. The C9 uses HEUI-style injection and injector part numbers vary by engine serial number prefix — this injector fits C9 engines specifying the 328-2574 injector group, used in Cat machines such as 330D and 336D excavators, 627G/637-series wheel scrapers, and D6-series track-type tractors. As a reman exchange part, a refundable core charge applies; return your rebuildable core for credit.
Symptoms of a Failing Fuel Injector
- Rough idle or engine misfire on one or more cylinders
- White or black exhaust smoke, especially under load
- Hard starting and diesel fuel knock
- Loss of power and rising fuel consumption
- Fuel in the crankcase oil or active injector fault codes
