original 268-1836 Fuel Injector 20R-9079 243-4502 20R-8057 241-3400 for Excavator C7 C9 new injector original new injector

Engineered specifically as an OE-style replacement for the C7 diesel engine platform, the 268-1836 fuel injector is designed to deliver precise fuel metering, fine atomization, and stable injection response within the C7 common rail fuel system. Its high-pressure resistant body, heat-resistant construction, and wear-resistant internal components support consistent spray pattern, controlled injection volume, and reliable combustion timing under the heavy-duty load cycles typical of C7 industrial and excavator applications. The injector is built to provide a direct-fit match for C7-powered machines, helping maintain original engine power output, fuel efficiency, idle quality, and exhaust behavior without requiring system modification.

This injector is matched to 324D, 325D, 326D, 329D, E324D, E325D, and E329D excavators, and is also catalog-referenced for C7-powered 584 / 584HD forwarder applications, making it suitable for construction machinery, mining, agriculture, forestry, industrial power units, rental fleets, and municipal equipment service operations. Authorized cross reference coverage includes 268-1836, 2681836, 243-4502, 268-1835, 268-9577, 263-8218, 295-1411, 238-8901, 241-3239, 328-2585, 328-2586, 387-9426, 387-9427, 387-9428, 387-9430, and 10R-4762, giving distributors and fleet buyers flexible sourcing options across multiple searchable part number formats for C7 engine maintenance.

For correct installation, confirm the old injector part number and engine serial number, clean the injector bore and fuel connections, replace sealing washers and O-rings as required, and follow the service manual for calibrated torque values and trim code programming into the ECM. Use clean diesel fuel, replace the fuel filter on schedule, drain the water separator, and keep the fuel tank free from contamination, as fuel cleanliness is the most important factor for C7 injector service life. Common warning signs such as hard starting, rough idle, misfire, power loss, black or white smoke, knocking, excessive return fuel, or check engine light should be diagnosed through fault code reading, cylinder cut-out test, injector balance test, and fuel pressure inspection before replacement.
