Caterpillar original Diesel Fuel 10R-3262 Common Rail Injector for C11 C13 Engine 345D 345C 349D 349D2 730 730C 980F 972H 980C D8N Excavator Replacement for OEM original new injector

The Caterpillar CAT C13 Fuel Injector 10R-3262 is an OEM-quality replacement component designed to deliver precise fuel atomization and consistent injection performance across demanding industrial applications. Manufactured with high-strength alloy steel construction and a corrosion-resistant surface treatment, this injector ensures long service life and stable operation under heavy loads and high-temperature conditions. It is engineered to meet OEM calibrated injection characteristics, supporting improved combustion efficiency, reduced fuel consumption, and enhanced emissions control.

This fuel injector is compatible with Caterpillar C13 engine models, including C13 ACERT, C13 Industrial, C13 Marine, and C13 Generator configurations, with selected C15 and C18 applications supported upon verification. It serves a wide range of heavy equipment, including Caterpillar excavators, wheel loaders, articulated dump trucks, mining machinery, generator sets, marine engines, heavy duty on-highway trucks, and industrial power units operating in construction, mining, heavy transportation, marine propulsion, power generation, oil and gas, and industrial manufacturing sectors.

The 10R-3262 injector assembly provides measurable performance benefits, including increased engine power output, stable idle performance, reduced engine vibration, and faster throttle response. To maintain optimal performance and service longevity, operators should use high-quality diesel fuel, replace fuel filters regularly, avoid water contamination, and follow Caterpillar maintenance schedules. Proper installation requires thorough fuel system cleaning, inspection of injector bore and seating surfaces, replacement of O-rings and sealing washers, adherence to Caterpillar torque specifications, and post-installation fuel system priming.
