Caterpillar original Fuel Injector 289-0753 for Diesel Engine, Replacement for OEM 234-1400, Cross Reference 10R-3263, 10R-0958, Suitable for CAT C15 C18 C11 C10 3406E Excavator original new injector

As a precision-manufactured heavy-duty diesel injection component, the Caterpillar 289-0753 fuel injector is exclusively engineered to fit CAT C15 series engines, including C15 ACERT, C15 ERT, industrial, generator, power unit and heavy-duty truck variants. Built to align with OEM specifications, it supports reliable engine operation across mining, construction, transportation, power generation and marine applications, and is suitable for engine overhauls, preventive maintenance programs, fleet management and OEM-equivalent replacement projects for global B2B clients.

Adopting an electronic unit injection structure, the injector operates under the command of the engine’s ECM: the solenoid receives electronic signals to regulate high-pressure fuel delivery, while the needle valve opens to atomize fuel into fine droplets for optimized air-fuel mixing. This design improves combustion efficiency, boosts power output, reduces fuel consumption and particulate emissions, and ensures stable idle performance. It also features OEM-level machining precision, high-pressure system compatibility, corrosion resistance and an optimized spray pattern for extended service life.

Each 289-0753 injector comes with a 12-month warranty and is packed in export-standard industrial packaging, with optional customized branding and global shipping via air or sea freight for bulk orders. To ensure compatibility, buyers are advised to verify part numbers against the engine serial number (ESN) before placing orders. All units meet strict industrial quality standards, delivering a dependable fuel injection solution for demanding operational environments.
