Volvo/mack I think uses cummins DPF components so you know one DPF system you know just about all of them. Detroits are a bit different but same basic concept. 

I have a basic understanding of cat's and cummins system but never worked on one. Do mack's use an 8th injector or do they use the engine injectors to inject fuel into the exhaust stroke? 

 

Ours have a "denoxtronic" system, whatever that is. Maybe bosch? They use an exhaust mounted HCI to create heta for the regen.

2 other issues this week.

So I do the emissions work at the farm, and as such I tend to do a lot of forced regens and data logging. This is the best heat I've had all week.

How about you? What do you look for in a regen before deciding to take a closer look? I'm not a mack mechanic, nor do I have any formal training. It's all been learned I  the seat or from whatever I can get my hands on.

yup think that's kind of rare for the n14 the small cam engines would do that on a regular basis! they when to bigcam then big cam2 and the issue faded !  Didn't work on these much!

It may be rare but at 20yrs old and approaching 1mil, I have 1 more that needs a cam. Can't get them though, N/A from cummins gotta go aftermarket.

We have 5 more identical trucks in the fleet, all 500hp 2001s

That's cool...  what are the gauge pics about?  just curious..  Is the engine back running again?  that would be cool to see..  I have never done a Cummin's...

Yeah it's running, it just rolled 1mil a few weeks ago.

Agreed on the 3406e. Or an n14 Cummins 

I just recammed a n14 this year. Learned a lot

What do I do? Everything I guess. Theres currently over 100 registered vehicles but I have 7 2012 CXU613 that have become revolving door problems for me, especially now it's getting cold. As the most computer literate person in house I do all the diagnostics for the farm by bosch ESI truck. Right now it's chasing low regen Temps and low catalyst efficiency causes. Honestly I'm getting to the point of needed better software, or chasing every component related to prove functionality.
