DPF on older truck??

Areelius,there is a big difference between DEF and non-DEF engines.
If you don't like any engine with several computers on it, that's fine, it is your choice.
But the way you portray it,you lump them all together. EPA 07 and EPA 10 engines.

 

I think what he means is much less STUFF to go wrong. Around here all shops are SLAMMED with trucks 2008's to brand new ones, tons of down time and lost revenue

 

Yeah, if you have multiple trucks, one of them can sit for a week, imagine being in east kabumfuk and being down for a week in a hotel

 

Sir,I agree that sitting for a week is unaccepteble.
BUT that has nothing to do with emmissions, that's a workshop giving poor service to it's clients.
Same for the injectors Areelius mentioned.

 

I absolutely agree, but a sensor issue or warranty repairs are taking days to figure out. I have a friend with a transfer.Got talked into a new 2014 389.In six months he claimed 49 days of unexpected down time in shop.Not ALL have been emissions Issues but thats a new one.God knows if you buy a trade in with 3,4,5 hundred k of hard driven ,below freezing miles on itWe're talking peterbilt, kenworth and, freighliner dealerships in a huge metro area.Imagine in some small town where they hardly ever see an issue like this, so they throw new parts at the problem and send you down the road.

 

Who knows,that smaller dealer might care more about his clients and have invested the time and money to go to the classes the brands want them to follow to keep up to date with modern times.
There is a thread on TTR by a warranty manager.
In it there is a story about how a dealer wanted the trucker to pay the work and parts for a repair done on a truck under warranty and then,according to that dealer,the trucker had to reclaim that money from Paccar,which is complete BS.
Would i trust that dealer to work on a'12..................NO.
But would i trust him to work on a '99,full mechanical engine......................?
NO WAY!!!!!!!
Because that dealer is just out there to get the $$$$$ from truckers.

 

I wouldn't just say Cummins are junk. Every engine manufacturer is having problems with meeting Tier 4 emission standards reliably. In the off road equipment world we're seeing all kinds of issues from this pollution garbage as well. I was recently talking with a Deutz engine tech who told me last winter alone they had over 100 new Tier 4 compliant engines in Western Canada fail and had to be replaced under warranty. At this point in time, from what I'm told anyways, is that this is the final stage for emission reductions so hopefully the manufacturers will be able to fine tune and improve on what we have today.

 

One would think so.
The "joke" is that if you were to drive with a EPA10 truck in Changhai,China the exhaust fumes would be cleaner then the air going in the engine.

Trucking has done it's part in emissions ,time for other industries to do the same.
