10 years since SCR technology on trucks

Was the one failure the def sensor or was it something else, I don't don't consider def to really be part of the engine it's its own little world of troubles. I'll go ahead and draw the line from all the troubles you hear about the new engines cracking cranks, fretting liners, and blowing rods to way too low of rpms, it just adds more stress to them. Engineering no longer seems to be about how long you can make something last but how "efficient" it is while alive, a truck that gets you 7.5 mpg but needs a crate engine every 600k miles isn't terribly efficient to my standards.

 

Agree with Oldiron here, apu equals success with newer engines.
The issue was a def sensor failure, it is literally the only issue with this engine thus far. We have followed Detroit's advice on pm's at 50,000 miles until they said start doing them at 75,000 miles. We will stick with 50 as apposed to 75 thank you.
I truly believe we will easily see a million miles on it before in frame. We currently have half the amount the amount I believe an inframe will cost us in a separate account. I think I'm looking at 30k for a factory in frame. Obviously, things like alternators and air compressors will go out and need replacing as we go. So far, tires have been our biggest expense, 4500$ for a set of drives.
We need this setup to last us another 5 years or so to retire. A new truck payment doesn't do anything for our retirement plans.
Once we own truck,( literally about to), we will be moving onto greener pastures and we will net a considerable amout more.
If I seemed a little harsh with my "clown" comment, I apologize to you all and one in particular. I sometimes get short when I'm sleepy.
I wish good fortune to you all and hope you are getting what you want out of this career.

 

For any that maybe interested, we are running 2.85 rears with the wide single 22.5 set up and DT12 AMT transmission. The entire driveline is Detroit.

Cannot for the life of me fathom why people would stretch out the cheapest possible maintenance item.

Especially considering that you can grease a truck every week in the calandar year (including the purchase of a $50 grease gun) for the price of around 4 "shop" grease jobs, even less if you factor in the fuel you burn and the time you spend dropping trailers and running around to these crooks who charge half hour or whatever to do it at $140 an hour

 

What do you want to grease?

 

Muffler bearings, mostly.

I'm confused. Or do you mean what my fee would be?

 

No.
I mean which parts will you grease every week?

 

I believe he is talking about the basic chassis lube.

Supposed to catch all the suspension bushings, Ball joints, U-joints, and the 5th wheel plate.
