Caterpillar original Common Rail Diesel Fuel Injector 4P-9076 7E-3382 4P-9077 0R-3052 Replacement for CAT 3508 3512 3516 Engines, Excavator, Dump Truck, Highway Truck original new injector

Engineered exclusively for the CAT 3512A V12 diesel engine platform in Caterpillar’s 3500 series, the 4P-9076 diesel fuel injector is an OEM-grade fuel system component purpose-built for heavy-duty industrial use. Cross-referenced to replacement part number 0R-9076, it is manufactured to meet or exceed all original Caterpillar specifications, ensuring perfect fitment and reliable operation on industrial, marine, power generation, and oilfield variants of the 3512A engine. It eliminates compatibility risks for maintenance teams and fleet operators managing mission-critical equipment.

As a core component of the Caterpillar diesel fuel injection system, the 4P-9076 converts high-pressure diesel into a finely atomized spray delivered to the combustion chamber at precisely calibrated timing via a precision-machined nozzle and needle valve. Its accurate fuel metering and optimized spray patterns deliver tangible operational benefits: improved fuel combustion efficiency, reduced fuel consumption, maximized horsepower output, lower smoke emissions, reduced piston and cylinder wear, enhanced cold-start performance, and stable frequency/voltage output for generator sets. It withstands thousands of injection cycles per minute under extreme operating conditions.

Validated for global deployment across heavy industry, the injector supports use cases including power generation for data centers, hospitals and utilities, marine propulsion and offshore platforms, oil and gas drilling and pumping stations, mining equipment, and construction heavy machinery. Every 4P-9076 injector includes a 12-month warranty, with worldwide distribution available to minimize unplanned equipment downtime for B2B buyers.
