This is the Alliant Power DT3411758R, a remanufactured CELECT Plus fuel injector for the Cummins M11. It comes from DTech, Alliant Power’s line of fuel system parts for legacy diesel engines, and it replaces Cummins 3411758, including the Cummins ReCon numbers 3411758PX and 3411758RX. The Delphi remanufactured version of the same injector is EX631758. A refundable core applies.

The M11 did not use one injector across the board. Parts catalogs list several CELECT injectors for it, including 3411752, 3411753, 3411754, 3411755 and 3411756, and each one is matched to the engine build by CPL. Catalogs tie 3411758 to CPL 2201 and CPL 2425, and Cummins and Alliant Power both describe it as an M11 bus injector. Most M11 CPLs call for one of the other injectors, so order this one when your old injector or your parts list calls for 3411758. The usual reasons to replace one are a miss, 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 M11 with the CELECT Plus fuel system, on engines that call for injector 3411758
• Catalogs list injector 3411758 for CPL 2201 and CPL 2425. The CPL is on the engine dataplate.
• Replaces Cummins 3411758, 3411758PX and 3411758RX
• Not for M11 engines that call for 3411752, 3411753, 3411754, 3411755 or 3411756
• 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.
