Engineered for the erpillar 3126 engine platform, the 222-5963 Fuel Injector is a new, OEM-standard Electronic Unit Injector (EUI) built for precise, high-pressure diesel fuel delivery. Designed as a direct replacement for OEM numbers 10R0957 and 0R8479, this injector fits 3126, 3126B, and 3126E engines, including marine, industrial, and generator variants. Precision-machined nozzle geometry and OEM-level dimensional accuracy ensure accurate fuel atomization, optimized combustion efficiency, and reliable power output under severe operating conditions.

Operating through an electronically controlled high-pressure injection process, the 222-5963 receives low-pressure diesel from the fuel gallery, while the ECM calculates engine load, speed, fuel demand, injection timing, and duration. The injector plunger then pressurizes the fuel, which is discharged through precision nozzle holes as ultra-fine atomized particles for clean, efficient combustion. This stable electronic control performance translates into measurable benefits: improved fuel economy, lower emissions, enhanced engine response, reduced fuel consumption, and extended engine service life.

Manufactured to ISO quality standards and backed by a 12-month warranty, the injector features corrosion-resistant construction and excellent thermal resistance for extended durability under heavy load. It serves construction excavators, wheel loaders, motor graders, mining equipment, articulated dump trucks, diesel generator sets, marine engines, commercial buses, medium-duty trucks, industrial power units, and air compressors. For buyers in construction, mining, marine, and power generation, the 222-5963 injector is a dependable replacement solution for global fleets.
