This is the Alliant Power DT3411766R, a remanufactured CELECT fuel injector for the Cummins N14 Plus. It comes from DTech, Alliant Power’s line of fuel system parts for legacy diesel engines, and it replaces Cummins 3411766, including the Cummins ReCon numbers 3411766PX and 3411766RX. Catalogs also cross it to Cummins 3411691. The Delphi remanufactured version of the same injector is EX631766 and the PAI number is 209993X. A refundable core applies.

The N14 did not use one CELECT injector across the board. Parts catalogs list 3411759, 3411760, 3411761, 3411762, 3411763, 3411764, 3411765, 3411766 and 3411767 as separate injectors, each matched to the engine build by CPL. Catalogs tie 3411766 to CPL 2390 and CPL 2591. Other N14 builds take other injectors, such as 3411759 for CPL 1807 and 3411761 for CPL 2027, so order this one when your old injector or your parts list calls for 3411766. The usual reasons to replace one are a miss, a rough idle, hard starting, white smoke, low power, or a cylinder cutout test that points at one hole. Check the injector harness and the fuel supply before you condemn the injector. The engine takes six.

Specifications

Fits / Applications

• Cummins N14 Plus with the CELECT fuel system, on engines that call for injector 3411766
• Catalogs list injector 3411766 for CPL 2390 and CPL 2591. The CPL is on the engine dataplate.
• Replaces Cummins 3411766, 3411766PX, 3411766RX, 3411766NX and 3411691
• Not for N14 engines that call for 3411759, 3411760, 3411761, 3411762, 3411763, 3411764, 3411765 or 3411767
• Six injectors per engine. This listing is for one injector.

CELECT injectors are driven off the camshaft, so set the valves and injectors (the overhead) to the Cummins procedure for your engine after you fit them. Make sure each injector has new O-rings before it goes in, and keep dirt out of the fuel passages in the head.
