Caterpillar original Caterpillar 235-1403 diesel fuel injector replacement for OEM common rail system new injector original new injector

The Caterpillar 235-1403 fuel injector is engineered as an OEM-equivalent replacement component for the C15 and C15 ACERT diesel engine platforms. Manufactured from precision hardened alloy steel, each injector assembly is built to meet original factory tolerances, delivering stable injection timing, superior fuel atomization, and consistent high-pressure performance across demanding heavy-duty operating cycles. The unit integrates seamlessly with the electronic unit injector (EUI) fuel system, ensuring precise metering and efficient combustion under severe load conditions.

This diesel injector assembly is designed for broad compatibility across Caterpillar-powered equipment, including heavy-duty highway trucks, mining trucks, articulated dump trucks, excavators, bulldozers, wheel loaders, generator sets, marine engines, and industrial power packs. Operators benefit from improved fuel economy, reduced exhaust emissions, and lower total operating costs due to the injector's excellent wear resistance and long service life. Quality-level manufacturing accuracy guarantees reliable performance in construction, mining, transportation, marine, and power generation applications across global markets.

Routine maintenance practices such as using ultra-clean diesel fuel, replacing fuel filters at recommended intervals, preventing water contamination, and conducting periodic injector testing help maximize component longevity. Each 235-1403 injector is backed by a 12-month warranty and is available in new or remanufactured conditions with flexible packaging options including neutral, OEM style, or private label formats.
