Caterpillar original Engine Diesel Fuel Injector 10R-7231, 10R-3265 for Caterpillar C15 C18 C32, 10R-2772, Replacement for 276-8307, for 395 374 3101 Excavator original new injector

Reliable fuel delivery sits at the heart of every heavy-duty diesel engine, and the Caterpillar 10R-7231 fuel injector is engineered to deliver exactly that. Built to OEM quality standards for the Caterpillar C18 platform, this brand-new injector restores factory-level performance in the proven 18.1-liter, inline-six, turbocharged diesel engine. It supports the full range of C18 applications, from construction machinery and mining equipment to marine propulsion, petroleum equipment, industrial power units, and generator sets.

As a precision fuel metering device within the electronic unit injection system, the injector receives high-pressure fuel and delivers it according to exact electronic control signals. Microscopic precision-machined nozzle orifices atomize fuel into the combustion chamber, enabling efficient mixing with compressed air. The result is improved combustion efficiency, increased power output, reduced fuel consumption, lower exhaust emissions, faster engine response, enhanced cold-start capability, and reduced engine noise—directly lowering operating costs across the equipment lifecycle.

Every 10R-7231 injector is produced with CNC precision machining and verified through flow calibration, spray pattern checks, leak testing, pressure testing, and durability validation. Wear-resistant, heat-treated internal components and corrosion-resistant surface treatments ensure long service life in harsh environments. Cross-referenced as 10R7231, with replacement references 10R-7230 and 10R-7232 through 10R-7235 plus related numbers 10R-7228, 10R-7229, 10R-7236, 10R-9787, 10R-8988, and 10R-2772, the injector is backed by a 12-month warranty—a dependable choice for dealers, rebuilders, and fleet maintenance providers.
