Caterpillar original Diesel Fuel Injector Assy Cross Reference 20R-3247, 392-6214, 20R-1275 for Engine Replacement for OEM, for Engineering Machinery and Diesel Car, 392-0225 original new injector

As a precision-engineered fuel system component purpose-built for Caterpillar’s heavy-duty diesel engine platforms, the CAT 392-0225 fuel injector assembly adheres to strict OEM specifications to deliver factory-matched, reliable performance. Designed for the CAT 3500 Series, it is fully compatible with 3512B, 3512C, and 3516C diesel engines across industrial, marine, mining, and power generation applications. It supports cross-referencing with reman, supersession, and secondary replacement part numbers including 20R-3247, 280-0681, and 386-1777, simplifying parts sourcing for maintenance and repair teams.

This high-pressure electronic fuel injector uses ECU-controlled precise injection timing and high-pressure atomization to optimize combustion efficiency, reduce fuel consumption, lower emissions, and maintain consistent power output. Constructed from high-strength alloy steel, it features precision OEM machining for direct cylinder head installation, corrosion and high-temperature resistance, and tight sealing to eliminate fuel leakage, extending service life under sustained heavy-load operating conditions.

It is compatible with a wide range of equipment including diesel generators, marine engines, mining power modules, oil and gas power units, industrial plant equipment, and emergency backup infrastructure. Each new OEM-equivalent injector comes with a 12-month warranty and is packed in export-standard packaging, making it ideal for global B2B engine maintenance, repair, and overhaul supply chains serving Caterpillar equipment operators.
