paccar mx 13 and isx 13

This could be true, many of the sensors and aftertreatment parts are identical. Also you have to remember that the mid range Paccar PX motors are just Cummins motors painted gray.

 

Yeah, same dosing injector, same DPF/DEF/SCR system, some other common parts outside of the aftertreatment system... which is why I think it lends credit to the claim. If the location of the dosing injector was part of an original design from Cummins, though, then I'm glad they at least abandoned that notion (although I'd rather service a dosing injector on a PACCAR than on the older Cummins engines... it's a PItA at first, but once you've got it, you've got it... the location of the doser on the backside of the pipe on the older Cummins to me is more of an annoyance at this point).
We're supposed to be getting more MX-equipped trucks, and word is that there've been quite a few improvements to the engine. Can you tell me a little bit about what those changes are? And is there any likelihood of Davey being made more user-friendly in the near future?

 

We are lucky that we can still get by with out all the emission c8ap.
The MX has been quite good with out all that stuff.
As for the DAVEY it could surely be improved if I compare it to Cummins Insite as far as ease of use or cost.
We decided not to get one for our shop because if only used once or twice a month the guys would not get the hang of it it is so tricky.

 

davie is terrible. davie 4 came out last year and is better, but the bar is so low any improvement had to make it better. the only thing that makes it better is the ease of software updates, other than that it still bites. Every chance I get I let the engenieers know how bad it bites too

 

Have a buddy that drive a new t-800 with the mx13 paccar and its lucky to get 5 mpg usualy 4.5 locally hauling grain and its powerless to me compared to my 500hp 60 series

 

Yeah, we have it all... DPF, dosing injectors, DEF, SCR... unfortunately, it'll be coming to construction equipment before too much longer, so I suppose it's good that I work on trucks now... if someone has a couple graders, excavators, etc., they'll have trucks supporting them, so I have to know something about working on trucks in order to go back to working on equipment... but the upside is that I deal with these catalyst systems so often that they'll already be familiar to me when I go back to working on equipment and those systems are present.
Davey, when compared to Insite... there's just no comparison. I work for a good sized company, and the majority of the fleet is Cummins, but we have a substantial enough number of the MX engines to justify the cost in Davey and the proprietary box they use... we use Inline 5 for Cummins, and I don't think I ever knew the name of the PACCAR one.
Even then, I'm still not getting the hang of Davey, Davie, however the hell it's spelled. I've figured out some functions, but I can't do half as much with it yet as I can with Insite.

 

In SA you can get DAF and Scania with the SCR (Add Blue) on Euro 5 spec.
People are so ignorant the sales people try convince them it is a cost advantage and desirable from a users point.

 

If you compare it to a EGR engine,i would agree.
There is a very good reason why Scania and MAN stopped selling EGR only EURO 5 engines.

 

I believe that (Compared to EGR) but when you can get an Euro 3 with out any of that from a pure operational and maintenance cost there is no choice.The MX in this configuration has been very good.If only they upped the durability of the oil coolers and wiring harnesses in the DAF application.

 

D20 is 10.5 Liters,that little engine can be rated at 2065 ft/lb , best part a complete engine overhaul for less than 5k$
