Can you beat it? DD15 1,165000 MILES

they do if they idle for 12 hours a day, engine and 1-box tied together with computer, once 1-box is clogged from idling the engine is electronically hamstrung until the 1-box is happy.

if 1-box were designed to be easier to maintain it wouldn't be a problem at all to idle, if you could just pop out the filters, swap in fresh sensors, there's not a lot to it. you could idle all the time and just do constant PM on 1-box.

but it's designed in a way that if you can't get one sensor out it goes from $50 to $5000 to $15000 inside a little 20ft/lb window

the $$$$$$$$ used for R&D comes from big dawg fleet suits, they use the designs in fleet only up to ~100k away from warranty expiration, where they can sell them off and still make bank before they become problem children. nobody gaf about OO equipment longevity. give it a few years I bet u see homemade turnkey aftermarket 1-box that use all factory sensors and filter cans with a non cloggable DOC and diet SCR. there's nothing to it, sure af not $15000 worth of tech. over a decade on now there's sure to be approaching the surface of a sustainable emissions logic in the works. in the form of on-board 50kw diesel generator and SIX HUB MOUNTED TRACTION MOTORS

 

EPA10 - every 5k or 8k active regen would start and it would take 3h to complete(at 800f) , sometimes i would see short 1100f regens depend on ambient temperature.
GHG17- every day active regen at 1100f and it takes from 10 m to 25m. after 6h idling parked regen will start automatic
just changing regen strategies we see now much less doc inlet pressure values. i am sure this will improve lifespan of the engine.

 

EGT is key, since these new trucks don’t have one.

 

Didn’t read all but I usually do the bearings and damper at 750k or so

Remember when a million miles was the norm?

 

It's the crappy tune that gets put in after the delete, especially the isx's. RAWZE is the man to go to for that. A few people over there write good tunes

 

That’s impressive man. Yea was gunna ask if you just haul really light stuff. Keep doing what you’re doing it’ll let you know when it’s ready to rebuilt

 

my truck is old, I like to keep it washed and de-greased regularly. But what I’ve found is power washing steering components does influx water into the joints a lot. So everytime it’s washed it gets greased. Something’s get over greased like S cam bushings . I don’t believe you can grease a truck too often.

 

100%.

You can see the water getting pumped out of the components as the grease starts to purge.

Even with equipment I prefer to grease the pins/bushings after a wash.

 

Beyond that, a worn steering component always shows less if the joint is full of grease.
