original 10R-47641 Common Rail Diesel Fuel Injector 10R-2828 263-8218 for E324D 326D2 C9 Engine new injector original new injector

Engineered specifically for the C9 ACERT platform, the 10R-47641 electronic unit injector delivers precision fuel metering through a seven-stage injection cycle governed by the engine control module. With an 8.8L inline six-cylinder configuration and ACERT emission technology, the C9 family demands fuel system components calibrated to exact OEM tolerances, and this injector meets those requirements with multi-hole nozzle geometry that produces an optimized spray pattern for uniform combustion. Hardened alloy steel construction, precision-ground internal components, and corrosion-resistant surface treatment allow the unit to withstand continuous operation in heavy-duty construction, mining, oilfield, marine, and power generation environments, with an expected service life ranging from 8,000 to 15,000 operating hours under normal fuel conditions.

The injector is a direct-fit replacement for part numbers 10R-47641, 326-1646, and 326-1647, covering C9, C9 ACERT, C9 Industrial, C9 Marine, and C9 Power Generation engine variants deployed across excavators including the 320D through 336D series, 966H through 980H wheel loaders, D7R, D7E, and D8T dozers, plus generator sets, mining machinery, and oilfield equipment. High-pressure resistance ensures stable fuel delivery under demanding load cycles, while ECM-controlled activation maintains fuel economy and lowers exhaust emissions across the full ACERT operating range.

Installation requires verification of the part number against the engine serial number, cleaning of the injector bore, installation of a new sealing washer, and reintegration of the fuel circuit with full priming and leak inspection. Depending on ECM configuration, injector trim coding and synchronization may be necessary after installation. Preventive maintenance includes the use of ultra-clean diesel, regular fuel filter replacement, frequent draining of water separators, and periodic injector balance rate checks to preserve long-term injection accuracy and engine performance.
