Caterpillar original 235-1400 Fuel Injector Excavator Parts Common Rail Injector 229-5919 for C15 C18 Engine, Replacement for OEM 253-0615, 10R-3264 Construction Machinery original new injector

The 235-1400 diesel fuel injector is a precision-engineered fuel system component tailored for Caterpillar heavy-duty engine platforms, delivering a dependable OEM-equivalent solution for equipment operators across multiple sectors. It is compatible with Caterpillar C15, C15 ACERT, C16, and 3406E engine variants, including those configured for industrial power units, power generation, and marine propulsion. The injector fits a wide range of equipment, from heavy-duty on-highway trucks and construction excavators to mining haul trucks, oilfield machinery, and stationary industrial power systems.

Operating within Caterpillar’s Electronic Unit Injection (EUI) system, the injector uses ECM-controlled injection timing and internal high-pressure generation to deliver finely atomized fuel through precision-machined nozzles. This optimized atomization supports thorough combustion, improving fuel efficiency, reducing exhaust emissions, stabilizing engine output, and extending overall engine service life. Wear-resistant materials and corrosion-resistant treatments enable reliable performance in harsh operating conditions, while OEM-grade dimensional accuracy ensures direct, hassle-free installation.

Every 235-1400 injector undergoes full performance testing prior to shipment to confirm compliance with OEM-level specifications. It is supplied in brand-new condition with a 12-month warranty and is available for global supply to support B2B equipment maintenance and repair operations. For long-term reliability, follow official Caterpillar installation torque guidelines, replace sealing components during fitting, use high-quality diesel fuel, and adhere to scheduled fuel filter replacement intervals.
