N14 Celect injector harness/plug

The Cummins on the Ag side I like .. but I still favor the Deere motors mostly because I familiar with them and in my view they are Equivalent to a Cat

 

The 8.1 is my favorite .. hard to beat the durability & their pretty much bullet proof .. those old 466's where by far the best back in the day..
The 8.3 in the magnum are good also

 

I don’t know if they might have different part numbers but I can say that they are all interchangeable if they do. Don’t just replace the o rings unless you want a temporary fix. The plastic seems to also compress and won’t provide proper crush on the new o ring. It’s also pretty common to see them leaking internally along the contacts. Which obviously won’t be fixed with an o ring. Usually you have to pull the intake manifold to get 1 or two of them. Should be just enough wire inside the rocker boxes to be able to unplug the injector from the inside without taking the top apart.

 

I used a pair of forceps to hold the harness while changing the pass thru. Didn't have to remove cover. It is difficult to change the one behind the intake manifold.

If you take the cover off. I would replace the piece that connects to the injector also.
I think that's when I did it. Memory is a little weak.

 

What's the history on injector harnesses and pass-throughs? The pass-through has an o-ring that eventually seeps, same as a CAT or any other engine. And worked on N14's almost daily for 6+ years and don't recall an epidemic of injector harness issues, so was curious what you mean.

 

I do my very best to stay away from any Cummins
I should of made it clear the ones I've had to work have had harness issues and the pass throughs always seem to be leaking is all
Everybody has their prefence..
My is not Cummins
