Caterpillar original Replacement Fuel Injector 250-1306 for PM3508B 3512B PM3516B, Cross Reference 162-8809, 392-0206, Compatible with 0R-8891, Excavator Diesel Spare Parts original new injector

Engineered for Caterpillar's 3500 Series heavy-duty diesel engines, the CAT 250-1306 fuel injector is a precision-engineered fuel metering component built for the 3512B engine platform. Operating as a high-pressure fuel delivery device, the injector meters accurately calibrated fuel quantities into the combustion chamber, where fuel passes through precision nozzle holes and atomizes into microscopic droplets. This process ensures complete combustion, maximum power output, optimized fuel economy, and reduced emissions, while improving cold-start performance and stable engine operation.

The 250-1306 is interchangeable with OEM numbers 326-1643 and 3261643, replacement numbers 10R-7222 and 10R7222, and cross reference numbers 317-7630, 3177630, 341-9876, and 3419876, simplifying procurement and inventory management for distributors and fleet operators. The injector is compatible with CAT 3512B, 3512, 3512C, 3516, 3516B, 3516C, 3508, 3508B, and 3508C engines, and is widely utilized across industrial power generation, mining operations, marine propulsion systems, oil and gas facilities, construction machinery, and emergency generator applications.

Every injector is produced through high-precision CNC machining from hardened alloy steel engineered for wear, corrosion, high-temperature, and fatigue resistance. Each unit is calibrated to meet OEM fuel delivery standards, and its optimized injection pattern delivers lower fuel consumption, increased thermal efficiency, and reduced operating costs. Designed for continuous-duty industrial service, the brand-new 250-1306 injector carries a 12-month warranty and suits engine overhauls, preventative maintenance programs, and fleet servicing operations.
