How long is the Detroit One-Box supposed to last?

See post #30. You probably have heard the saying you get what you pay for. There is a reason the cheap ones cost less. They use less of the precious metals (catalyst) that cost so much. Less means they don't last anywhere near as long. The DOC and SCR (C stands for catalyst) are just like a catalytic converter in a car.

 

Another reason they cost less, it's not marked up by a truck dealership.
I haven't compared quality, not sure how to check.
It would be nice if the parts could be replaced inside. Instead of having to replace the whole box.

 

if you can get a heart transplant, you can get a DOC transplant. for less than 18k jfc. *googles local precision welding*

 

I remember reading on here about some shop in Ohio that could replace them I believe. They could open the one box tourch them out and put the new ones. Then weld the them back in plces(the box that hold them) then put the one box back together. Kinda like Cummins they built their in 3 parts so you could replace just the parts that fail.

 

Are you talking about that guy named Ryan that has an shop that specializes in emission systems and polar fox apus?

 

I just had my filters baked. $1700 OTD.

 

Whats the mileage in your onebox and filters?

 

Truck is 630K

I got it at 370K, and the filters had just been baked.

Lately it seemed like it wouldn't quite regen all the way, and I'd get CEL and it would derate, then it would clear.

So we'll see.

DD15 Cascadia.

Seems like most Onebox's go teets up between 500K and 600K.

I have a tripac and never idle.

The aftermarket OneBox from Dale's Diesel is about $7500 and comes complete minus sensors, but includes gaskets and clamps. 3 year warranty.

The one from Freightliner For The Criminally Insane is $10K, plus filters, plus sensors, plus clamps, so like $15Kish. 1 year warranty.

You decide.

 

I replaced my filters with new. Baking never gets it as clean as new. 2400 for the filters and gaskets and clamps. Takes less than an hour on a western star. But you need the computer to enter the new filter numbers and reset everything.

 

It's not just whether one idles or not. Fuel additives such as Howes or PP help.
1 - Oil samples show less soot. Soot is abrasive so less wear.
2 - Additive lubricates and cleans
3 - Increased mpg where the fuel savings OTR exceeds the cost of the additive
4 - less regens when using an additive so filters last longer
That 3 yr warranty on the aftermarket is probably pro-rated.
3 yr vs 1 yr in reality is most times not a valid comparison. One real life example: OE part lasted x miles and cost twice the aftermarket (call it AM) part with a lifetime warranty. Cheap ##* customer required AM multiple times. AM part only lasted 1/4 to 1/6 the miles of the OE. So even with the warranty the AM part costs more because the labor over x miles is 4 - 6 times more and that does not even include downtime.
