Perkins original Perkins 269-1839 Common Rail Fuel Injector Replacement for C7 Engine Diesel Engine Fuel Injector Assembly new injector original new injector

The Perkins 269-1839 Original OEM Diesel Fuel Injector is engineered as a direct-fit replacement for Perkins C7 and C9 diesel engine platforms, including C7 ACERT, C9 ACERT, and Perkins 3126E configurations. Manufactured to OEM-equivalent tolerances using hardened alloy steel construction and wear-resistant nozzle components, this electronic unit injector delivers stable fuel atomization under high-pressure common rail conditions. The assembly is precision-machined, corrosion-resistant internally, and validated through 100% flow testing, leak back testing, and spray pattern verification to ensure consistent injection quantity, correct timing, and dependable cold-start performance across demanding duty cycles.

This injector is designed to restore factory engine performance, providing improved combustion efficiency, enhanced power output, reduced fuel consumption, and lower exhaust emissions. It serves as a cross-reference for part numbers 10R-7225, 238-8091, 238-8090, 238-8901, 241-3239, 243-4502, 268-1836, 268-1840, 293-4071, 293-4072, and 295-1412, allowing direct substitution across a wide range of Perkins-powered equipment. Routine diagnostic procedures such as injector resistance tests, cylinder cut-out tests, fuel pressure verification, and ECM signal analysis can be performed to confirm operational integrity before and after installation.

The 269-1839 injector is widely deployed in excavators including E320D, E323D, E324D, E325D, E329D, and E330D models, as well as in Perkins generator sets, marine auxiliary engines, mining haul trucks, and heavy-duty construction machinery. Recommended installation includes cleaning the injector bore, replacing the copper sealing washer, applying OEM torque specifications, reconnecting the electrical harness, and priming the fuel system. Backed by a 12-month warranty, this OEM-quality injector supports reliable operation in construction, mining, power generation, marine, and global transportation applications.
