Caterpillar original  253-0617 10R-3266 249-0709 10R1273 10R-9236 Diesel Fuel Injector for C15 C16 C18 C27 C32 365C 374D 385C 390D D10N D11R original new injector

The Caterpillar 253-0617 fuel injector is engineered as a direct OEM-equivalent replacement for CAT C15, C15 ACERT, C16, and 3406E diesel engines operating across construction, mining, marine, power generation, and oil and gas applications. Built from high-strength alloy steel, the injector assembly features a precision-machined nozzle that delivers consistent high-pressure fuel atomization for improved combustion efficiency, reduced fuel consumption, and lower exhaust emissions under demanding load conditions.

Each 253-0617 injector is manufactured to OEM calibration standards and factory-tested to confirm reliable metering, stable injection pressure, and long operational lifespan. The corrosion-resistant construction and high-temperature durability make it suitable for heavy equipment, generator sets, marine engines, and vocational vehicles operating in harsh industrial environments. Compatible cross references include 10R-7225, 20R-8064, 328-2574, 387-9433, and 392-0204, allowing flexible replacement across multiple CAT engine platforms.

The electronic unit injection design supports precise fuel delivery, enhanced cold-start performance, and increased overall engine reliability. Backed by a 12-month warranty and supplied in export-standard industrial packaging, the 253-0617 injector is available in new or remanufactured configurations to meet diverse fleet maintenance requirements. Always verify cross-reference numbers against engine serial number and calibration code before ordering.
