Built for direct replacement service on C9 series engines, the assembly supports stable combustion, balanced cylinder performance, and reliable output across long duty cycles in construction and industrial applications.

Cross-reference compatibility covers 328-2580, 387-9431, 10R-9003, 20R-8069, 293-4074, 267-9710, 573-4231, and 20R-8846, giving procurement teams broad interchange flexibility and reducing wrong-order risk. Typical applications include 330D and 336D excavators, with additional field references to 336, E330D, E336D, and E340D units where serial number, injector code, and ECM calibration verification are recommended. Heavy-duty internal construction, fine spray geometry, and searchable cross-reference support make this injector suitable for full-set replacement on high-hour engines, bulk fleet servicing, and B2B aftermarket distribution.

Proper installation with clean diesel fuel, scheduled fuel filter replacement, regular water separator draining, and injector balance monitoring will maximize service life. Symptoms such as hard starting, rough idle, black or white smoke, misfire, power loss, fuel knock, or elevated consumption should be diagnosed with approved equipment before replacement, ensuring accurate root cause identification and dependable long-term performance.
