Caterpillar original Fuel Injector for C9 C9.3 Engines, 382-0709, Cross Reference 364-8024, Replacement for OEM 367-4293, 456-3509, for Excavator 336E 336EL 336ELN D6T D7E original new injector

For B2B heavy equipment parts buyers, fleet maintenance teams and diesel engine rebuilders, the CAT 382-0709 is an original-standard common rail fuel injector purpose-built for the Caterpillar C9.3 diesel engine family. Classified officially as an "Injector Gp" by Caterpillar, it delivers precise, timed fuel metering and atomization as part of the engine’s high-pressure fuel injection system. It is engineered with specialized metallurgy and proprietary manufacturing processes to align with modern performance, injection pressure and emissions requirements, matching original equipment specifications for C9.3 engine service use.

This injector is cataloged for a wide range of Caterpillar C9.3-powered construction, earthmoving and mining equipment, including 12M 3 series motor graders, 336F L excavators, 725C articulated trucks, D6T track-type tractors, 966M/972M series wheel loaders and 627K wheel tractor-scrapers, with D7E applications listed in some supplier catalogs. Market cross-reference candidates include 456-3509, 20R-5075 and 386-1809, but these are not guaranteed replacement numbers. All fitment must be verified via machine serial number, engine serial number, arrangement number, ECM calibration and original injector part number before purchase, per official Caterpillar guidance.

Suitable for service, replacement and engine rebuild programs, it supports aftermarket repair, fleet maintenance and parts distribution use cases. As the official Cat 382-0709 part is marked as discontinued, it offers a specification-aligned replacement for C9.3 engine upkeep, with pre-shipment configuration confirmation recommended.
