Caterpillar original 107-1230 Replacement for OEM Diesel Engine Injection Nozzle Fuel Components for 3116 C3116 E320B E322B E325B Excavator Truck Auto original new injector

The Caterpillar 107-1230 fuel injector is engineered as an OEM-quality replacement component for CAT 3114, 3116, and 3126 diesel engine platforms, covering 3116TA, 3126B, and marine or generator-set configurations. Built with precision fuel metering and stable fuel atomization characteristics, this injector assembly delivers consistent spray patterns that support efficient combustion across demanding operating conditions. The heavy-duty internal construction features corrosion-resistant components and a low-leakage design, contributing to extended service life and reliable performance in industrial, marine, and power generation environments.

Installed within the diesel direct injection fuel system, the 107-1230 injector receives pressurized fuel from the transfer pump into its internal chamber. As pressure rises, the needle valve lifts once the calibrated threshold is reached, allowing atomized fuel to pass through precision nozzle holes into the combustion chamber. Following combustion under compressed high-temperature air, the needle valve reseats to conclude each injection cycle. This working principle translates into measurable operational benefits, including increased combustion efficiency, improved fuel economy, lower emissions, reduced smoke output, and better overall power response.

The injector is suitable for excavators, wheel loaders, motor graders, pavers, scrapers, mining equipment, agricultural machinery, generator sets, marine vessels, industrial power units, and heavy-duty trucks. Authorized OE and cross-reference numbers include 107-1230, 1071230, 127-8222, 1278222, 4P-1731, 4P1731, 0R-8461, 0R8461, OR8461, OR-3580, OR3580, CA1071230, CAT1071230, INJ1071230, and CAT3116INJ1071230. Each unit is factory performance tested to ensure proper calibration, stable atomization, and dependable operation across construction, power generation, marine, transportation, and agricultural sectors.
