Caterpillar original  269-1839 C7 Common Rail Fuel Injector 268-9577 295-1410 328-2576 243-4503 Replacement for OEM Engine Fuel Injector Assembly original new injector

Engineered for demanding heavy-duty diesel applications, the 269-1839 fuel injector delivers OEM-level performance for C7, C7 ACERT, C9, C9 ACERT, and 3126E engines. This electronic unit injector is fully interchangeable with cross reference numbers 10R-7225, 238-8091, 238-8090, 238-8901, 241-3239, 243-4502, 268-1836, 268-1840, 293-4071, 293-4072, and 295-1412, providing fleet operators and industrial buyers with a reliable sourcing solution for excavators, generator sets, marine engines, and mining equipment.

Manufactured with hardened alloy steel bodies, wear-resistant nozzle components, and corrosion-resistant internal parts, the 269-1839 injector features precision nozzle calibration and high-pressure sealing technology built to OEM machining tolerances. Every unit undergoes 100% flow testing, leak testing, spray pattern verification, and durability validation to ensure stable fuel delivery, superior atomization, and optimized combustion. The result is enhanced engine power output, improved fuel efficiency, reduced emissions, and lower long-term maintenance costs across E320D, E323D, E324D, E325D, E329D, and E330D excavator fleets.

Installation requires thorough cleaning of the injector bore, replacement of the copper sealing washer, torque-to-spec mounting, secure harness connection, fuel system priming, and injector cut-out verification. Recommended diagnostics include resistance testing, fuel pressure testing, leak back testing, spray pattern analysis, and ECM scanning. Backed by a 12-month warranty, this injector is a proven choice for construction, mining, power generation, marine, and transportation industries worldwide.
