original 111-7916 Mechanical Engine Parts Diesel Fuel Injection Pump Injector 153-5938 20R-4148 173-4061 177-4754  original new injector

Engineered specifically for the 3126, 3126B, and 3126E inline 6-cylinder industrial diesel platforms, this diesel fuel injector 111-7916 delivers factory-level compatibility and stable injection performance across a wide range of operating conditions. The unit is built to match the original HEUI fuel system architecture used in the 3126 engine family, allowing for direct-fit installation without additional modification. Extensive cross-reference coverage—including 1117916, 116-3526, 116-7150, 104-3377, 173-4061, 173-9267, 0R-9348, 0R-9350, 232-1173, 222-5972, 20R-8758, 10R-9239, 188-1320, 173-9379, 4CR0197, and 198-4752—ensures the injector serves as a dependable replacement option for fleet operators and maintenance workshops managing mixed engine inventories.

The injector body and nozzle are precision machined to maintain consistent atomization, while heat-treated high-strength internal components provide resistance to thermal fatigue and high injection pressures. A corrosion-resistant surface treatment protects the assembly from moisture, fuel contamination, and harsh under-hood or marine environments, contributing to an extended service life. Each unit is designed to meet or exceed OEM rigidity and durability standards, and is individually tested for leak integrity, spray pattern uniformity, and pressure response prior to dispatch.

Field-proven in heavy-duty truck fleets, wheel loaders, excavators, industrial power units, generator sets, marine propulsion systems, and agricultural diesel equipment, this 3126 injector offers a reliable aftermarket solution for both routine service and engine overhaul applications. Buyers benefit from broad cross-number interchangeability, stable quality control, and packaging suited to international B2B distribution.
