WE ALL AWARE THAT MACK TRUCKS USE A REGENERATION SYSTEM ON THEIR TRUCKS SINCE 2008.

HOWEVER, ARE YOU AWARE THAT IN 2008 THIS SYSTEM DIDN'T HAVE IN CONSIDERATION TUCKS THAT NEED TO IDLE WHILE WORKING AND WAS ONLY SUPPOSED TO BE FOR LONG HALL TRUCKS ?

IF YOU OWN A 2008 MACK TRUCK THAT IDLES WHILE WORKING (CONCRETE PUMPS FOR EX.) AND YOU HAVE HAD YOUR TRUCK BACK TO MACK SHOP OVER AND OVER AGAIN, TRYING TO FIX THIS PROBLEM THAT, BY THE WAY, IT'S NOT FIXEBLE, AND SPENT THOUSANDS OF DOLLARS TRYING TO DO SO, PLEASE CONTACT ME.

I WOULD LIKE TO START A "MOVEMENT" TO HAVE MACK ADMITING FAULT AND CHANGE THE SYSTEM ON THESE TRUCKS.

ONE VOICE IS NOTHING BUT WE ALL CAN MAKE A DIFFERENCE.

tHANK YOU!

I am down for helping you. Give me a call when you got a second.

I know there are a lot of 2008 out there, what are you guys doing?

what we do is fix them everytime they sotp working.

mack even hides that this is a problem.

NOBODY HAS ANY INFORMATION OR THE SAME ISSUE?

YOU CAN MESSAGE ME PRIVATELY.

What would happen if you change the ECM to a 2007 and chuck the filter.

I don't really know (office personnel) but i'll ask the shop guys; however, if it was something simple people wouldn't be having all of these problems and mack would have fixed them. i think...

thank you for your input

We had trouble with Isuzu trucks. They ended up re-programing the computer to bypass the parking brakes being engaged as well as the rear tailshaft/diff not turning. Took a hell of a time to get the Japs to authorise the dealers to change the computer. It may never had happened until over 4 Isuzu bush fire-engines went into "limp mode" in wild bushfires  and they could not out run the fire storm ... all the crews were killed.

Good Luck trying to get Mack to admit fault on anything.

Was anybody on here at the ACPA education conference last week? If you were you would have heard Mack's position on cleaner emmission requirements at the talk they gave at lunch. Short version - EPA bad, not Mack's fault. Quote "We think it's terrible what the EPA is doing to you".

Its not just Mack or Concrete pumps.  All newer diesels are dealing with these issues and having problems.  No one likes it but we have no choice about it.   There is no way to control diesel fumes at idle. 

what i don't understand is why we should pay the bill, (in my case to mack because i take my trucks to them) everytime that happens? shouldn't mack pay these bills?

It looks to me that mack has not done anything to fix these problems because the less these trucks work, the more mack makes.

I think that if everybody that spends money trying to fix a problem that we all know is defaulted things would be different.

i'm certainly gonna try...

Never been there,but,British Columbia,is one of the most beautiful and seemingly cleanist and enviromentally conscious places on Earth.            I live 30 miles from cancer alley in Louisiana,choke-choke,the lower Miss. River,probably 100-200 chemical plants and refineries,we do have good red beans.........Keep our states/provinces clean,free from carcinogenic substances while we still have the opportunity

Coudn't agree more!!!

We definately wanna keep our environment the way it is; however, to be able to support the environment we need to be able to keep a strong economie.

If small companies spend money that shouldn't be spent just because the big ones already have their piece of the pie and don't care than, the environment will suffer for sure!

no small companies=no jobs=no taxes=no causes    :)

that's how i see it!

i never said not to worry with the environment. what i'm saying is that they need to create a product that works with trucks that need to idle while working. :)

Meanwhile fix the one that already are on the market and make sure that we, the small guys, don't pay the price.

2+2 should equal 4      weak econemy should not equal dirty environment     Big guys have to pay for repairs also      Keep B.C. Clean

Have you talked to the pump manufacturer about a fix or possible solution ?

I just cut all that crap off my 08 Duramax because of a constant regen problem.  Left me with 12 mpgs on the highway. Tuned it and its back up to 19 mpgs highway. I was talking with a driver yesterday about this and he said they are due for new trucks next year. I was wondering about the DPF as when they idle to much, the soot builds up and causes a regen. Not sure how the equipment does it, but my truck you had to drive above 30 for about a half hour until it was done. How the heck are you gonna do that in the middle of a pour?  That's why the DPF fails on these things. Also are you guys checking your oil for diesel?  The first gen DPF Duramax injects diesel on the exhaust stroke and has issues with washing the cylinder walls out and getting diesel in the oil. I cut mine out, sounds awesome now, because I don't have to worry about DOT, unlike you pump guys.  Can't delete that stuff unfortunately.  I don't even think there are tuners out there for it.  

Also the DPF went into place to get rid of the soot. Proper tuning and air fuel ratio makes for clean exhaust. 

Thats why I like my EFI  Live :)

No Canned Tuna!  Now if he would tune equipment....

we have a 2009 isuzu npr400 with the particle filter sure am glad now that we dont run a pto, feel for you guys, just not fair

I find it  interesting, that the MR became somehwat the standard truck to be used as carrier for pumps. I think this is mainly due to the pump manufacturer dictating this. A cab over is the standard in Europe, Mercedes or Volvo should not have a problem offering a truck that could be used as pump carrier, as they are already used to mount pumps.  The particle filters are being installed in Eurpe since the late 90's, that is not an exaclty new technology, apparently for Mack it is.

there is a fix for these model trucks, they are not designed from factory to regenerate in pto, I have one that is setup to regenerate in PTO , we have been running it for 6 months , and did have one issue but it was covered under warranty.

Mack will never admit, anything, but worth the effort. My 2012 has been in the shop more than operating, but she has been kleen for three weeks, now. We should have a Mack AAA club. They had to re write the software, and fix almost every loose nut bolt and screw in the silly thing. The $20,000 muffler system, I am glad I do not own it, I would have used a safety whip check road the boom up and hung myself by now.

Ran one for a while..after service tech came out and regened with laptop because of level 4 alert and power loss...it worked okay then with a close watch on alert light in dash.  If level one is flashing and regen is not active manually initiate it and continue operation.  If it reached level 2, disengage PTO and manually initiate and wait for cycle to complete.  We never drove it over job site speed for 4 months but seemed to work.  Biggest frustration was complete lack of instructions in mack operators manual.  These suggestions came from Volvo service tech who showed up.  Seems like mack would put very clear cut instructions for use when its possible to cost yourself a pile of money by not using it right.
