Oil Pressure Issue Cummins N14

I had the same situation in Lexington,KY
As you are having drove to the freightliner dealership and they replaced all the pickup oil tube clamps ....Same engine .

 

When it comes to putting the pick up tube back on, I always tighten the retaining clip on the oil pump side first, then tighten the flange on the oil pan side. The oil pan can flex a bit, and I’ve found that it seals better that way, for no oil leaks at the pump (even though it’s opposite of Cummins spec!) you did do the two o-rings right? The one in the retaining clip on the oil pump side, then the one under the flange on the pan side?

I got a video on YouTube doing the pan, cooling nozzles and pick up tube. Sounds like you got it going though!

 

Yeah that sounds right, I don’t think there should be much or any play on the inside. But honestly, I can’t remember last time I did it, what the play felt like. How can you feel the play? By moving the external transfer tube by hand?

I do understand wanting to pull the pan back down to inspect what it may be, though that means probably needing a new pan gasket(?) wish I could remember a bit better, but my intuition says the same, that the external transfer tube should be firm to the touch when pushed on.

It’s just the two female bolt receivers on the inside right? I went back in my video and couldn’t really tell what holds the interior pick up tube in place besides that clamping together force with the two bolts, and some mounting bolts further down the pan.

 

Yeah! I hear you on being able to do it twice as fast now. That was my first time on that video, just feeling my way through. I had already experience with doing the oil pump and pick up tube, but not the pan.

is there someone you can ask in town? To bad nobody on here has chimed in yet on this particular part. Could possibly save you some time and money. But it would also be a waste to put $150 worth of oil in just to watch it leak and have to drain it all again. But I guess if you have a clean way to catch your oil like I do now, you might could give it tr

But your right. Now that I think about it. Doesn’t the internal pick up tube poke outside the pan just a smidge? Like a 1/4 inch or so? I faintly remember that, because that’s where the O ring goes around right? I might be misplacing a memory here. But if that’s the case, if the internal side is not poking out then your just at the mercy of the external flange against the o ring, which is not by design, if that where suppose to be the design, it would just be a flat gasket I’m thinking. Plus if there’s a gap between pipes, the suction of the pump will probably be off since there’s not a direct flow available from the internal pipe AND, possibility of unfiltered objects getting through that gap.

so with all of that being said. Since you know for sure the internal pipe slid back, then yeah something doesn’t seem right. Question is also, what made it slide back? And how to properly secure it so it doesn’t repeat its motion backwards in your next instal.

 

sounds like a win! YouTube has helped me so much over the years, so I decided at some point to pay it forward, especially on videos that weren’t there to help me. Sounds like you got it going on the right track.
