CM2250

I'm gonna say $10,000.
And they gonna find the source of the oil consumption is carbon packing around the rings.

If I get to that point, probably get a Recon. Just because you get new or recon turbo, actuator, fuel pump, ecm, and wiring harnesses.

Are you doing any oil analysis on it?

Do one before you do it, and see what Cummins says about the report.
I'd love to know how your EGR cooler, and fuel pump are holding up at that mileage.

Not saying Oh God Brad you so lucky, just like to hear from someone hands on, cause of all the negative talk.

 

I'll keep ya posted Dave and yes that's probably what they will find as they have on the last 3 they have done ....as I mentioned my fuel pump was updated before the recall as were all of the mates to mine and it hasn't been an issue since ...and I've had no egr issues .
I'm pretty sure I could get 800k out of it but I'd just rather have it done on my time and terms and not under a load a long ways from home ...easier to plan financially this way than waiting for a catastrophic failure a long way from home dealing with people I don't know sitting in a motel for 2 weeks or more ....or have it hauled all the way back to Omaha and getting charged to repower a load .
Much easier to have done here in a planned manner while I sit in my heated garage watching it snow with cold beer and fire up my new snowblower lol.

 

Oh I agree 100%. Anything big to be done, definitely at home.

 

Make sure they check your counterbores really good. And if they won’t let you watch the measurements before the cut & after the cut (if you need cutting) , that would concern me. Not only is a good counterbore cut around a thousand dollars, but who’s to say they actually did it or not. Just looking out. Those counterbores need to be right in spec or that head, gasket & block won’t mate well.

It’s better knowing for sure with your own eyes that the measurements are right. So you cant blame yourself later for not checking.

FYI: a little story on recon isx’s. A friend, who owns a high traffic independent shop, bought a new recon long block, as the customer requested. When checking for something internally he decided to check the deck height just because. Sure enough, one of the liners maybe a couple were already almost out of spec on the low side. I think one was low for sure, out of spec. That motor would of probably blown the head gasket pretty quickly. Of course it would be under Cummins warranty, as long as they couldn’t stick it on user error somehow. But just goes to show.

Good luck

 

I've asked the wrench that does a lot of my work, the kid that's his apprentice that's going through the full Insight School, and Cummins about a lot of the stuff that's posted on TTR.

And they all are starting to look at me like " Are you F stupid?"

 

We all can believe what we want. I’m simply pointing out first hand experience. And 2nd hand experience through my first hand experience with people I trust. Some things on here are iffy, but the pumps have a real track record.

 

Just like @Justrucking2 , I think his redo overhaul was over a paid for counterbore that was never cut or not cut right + dealer install wrong engine model parts. But I don’t mind hushing up about stuff, just if I can see on here that I might can save someone some time or money on certain things, and they seem like an honest person working hard, I do. But I’m not here to convince anybody about anything really. I say my piece and that’s it lol.

Because I know I’ve got much help from folks along the way, and wisdom on mechanical things.

But anyways, I’ve heard a lot of things from a lot of people. many of it negates itself. Some swear by one motor and the rest are trash and etc. ... the thing is; plenty folks are out here with exploding fuel pumps and bad rebuilds. Nothing to be scared of, but something worth knowing.

 

X15 Economy uses the same pump as the 2350s.
X15 Performance uses a 2 cylinder unit pump design with 2 feed lines to the rail. Kinda similar to a MX 13 fuel pump design.
If a cam/follower was to fail debris could still enter the oil system. Looks like the followers have a new coating to prevent this though.

Have not seen an X15 pump fail firsthand yet. Have a couple at 700,000km.
Have not see steel plungers fail yet.
Fuel pump camshaft/follower failures have slowed considerably from what they used to be.

 

@bzinger did you or do you kick your idle up when idling?

Wrenches tell me that's the key to preventing the carbon packing.

You gonna get an APU??

 

They never machined the block at the time of my in frame, even though they said they did... And your comment about the factory reman motors, it is true regarding the sloppy counterbores, Mr Haggai has seen it in his shop, liner heights all over the map. Cummins is really sloppy lately in their manufacturing processes.

If you in frame these Cummins motors, the block HAS TO BE MACHINED! There is no way around it, it is right there in the manual, cut and shim the block to set the liners at the proper heights. And heights need to be measured at min four sides. A special tool is required to set the liners, without the tool, you will not know what the real liner heights are.

Here is the tool that is used to machine the block... See that blue tape in the cylinder hole to the left of the pink tool? Just above it is the ledge that is machined, that lip, the bare metal. The bottom edge of that is what is cut, along with the deburring of the side of that lip. Then a brass copper looking ring is placed on that ledge after cutting, that is called the shim. The piston liner is then placed into the hole and eased into position. See the next step immediately below, the liner instal tool.




Here is the tool used to set the liners and measure the actual liner protrusion.



Here we are measuring the deck and the liner protrusion. This is a photo of the original liners before being removed. They were all over the map, from .0008 to .0012, one liner measured .0009 on the left side and .0011 on the other side. This is not rocket science, you just have to take your time and do it right. These measurements were from my first in frame, the block was not cut and the liners just thrown in. Pretty obvious why the head was taken out.
