This is the Alliant Power DT3411759R, a remanufactured CELECT fuel injector for the Cummins N14. It comes from DTech, Alliant Power’s line of fuel system parts for legacy diesel engines, and it replaces Cummins 3411759, including the ReCon number 3411759RX. Catalogs cross 3411759 to the earlier Cummins numbers 3087560, 3083846 and 3087733. The Delphi remanufactured version of the same injector is EX637560. 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 3411759 to CPL 1807. The N14 Plus engines take other injectors, such as 3411761 for CPL 2027 and 3411766 for CPL 2390 and 2591, so order this one when your old injector or your parts list calls for 3411759 or 3087560. 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 with the CELECT fuel system, on engines that call for injector 3411759
• Catalogs list injector 3411759 for CPL 1807. The CPL is on the engine dataplate.
• Replaces Cummins 3411759, 3411759RX, 3087560, 3087560PX, 3087560RX, 3083846 and 3087733
• Not for N14 engines that call for 3411760, 3411761, 3411762, 3411763, 3411764, 3411765, 3411766 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.

Frequently Asked Questions

What Cummins number does the DT3411759R replace?

Cummins 3411759, including the ReCon number 3411759RX. Catalogs also cross it to the earlier Cummins numbers 3087560, 3083846 and 3087733, and the Delphi remanufactured version of the same injector is EX637560.

Will the DT3411759R fit any Cummins N14?

No. The N14 used several CELECT injectors and each is matched to the engine build by CPL. Catalogs list 3411759 for CPL 1807. Order this one only when your old injector or parts list calls for 3411759 or 3087560.

Is the DT3411759R new or remanufactured, and is there a core?
