Caterpillar original 235-1400 Diesel Fuel Injector Replacement: 10R-0956, 355-6110, 253-0618 Common Rail Injector for Caterpillar C15 C18 Construction Machinery original new injector

Engineered for Caterpillar heavy-duty diesel engines, the 235-1400 fuel injector is a brand-new, OEM-equivalent component designed for C15, C15 ACERT, C16, and 3406E platforms. It supports a wide range of equipment, from heavy-duty highway trucks and construction excavators to mining haul trucks, wheel loaders, power generation sets, marine engines, and oilfield equipment. Cross-referenced with 2351400, 10R1273, 10R0957, and 10R1275, it gives buyers a dependable sourcing option with global supply availability.

The injector operates within Caterpillar's Electronic Unit Injection (EUI) system: fuel is drawn from the supply circuit, the electronic control module determines injection timing, and high-pressure fuel is atomized through precision nozzles for efficient combustion. Precision-machined internal components ensure accurate fuel metering, while high-pressure injection technology improves atomization. Wear-resistant materials and corrosion-resistant treatment extend service life in demanding environments. Fleet operators benefit from improved combustion efficiency, reduced fuel consumption, lower exhaust emissions, and stable long-term engine performance.

Each unit is performance tested before shipment and built to OEM dimensional accuracy for direct installation, backed by a 12-month warranty. To ensure correct fitment, buyers should verify the engine serial number (ESN) before ordering, as cross-reference data may vary by regional Caterpillar service database. Installation should follow Caterpillar service manual torque values, with sealing components replaced and injector coding performed where required. Clean fuel and regular filter replacement are recommended to maximize injector service life.
