We are located in Central Nebraska. We never get up to road speed. Generally, do not get above 25 mph very often. Do not have trouble getting feed out, can not get a large load out in 1 pass, but that is due to the ration and mixer. We have Roto-Mix boxes. I called the Mack One on Monday, which got us some action. Our local service rep. and District Service Manager were here yesterday. They had a service tech come up and do manual Regens on all 3 trucks. Our regens were not getting the DPF cleaned. THey also did some updates to the programming for the Regens. We are hopeful (but doubtful) this will work. After the Manual Regens, we were told to rund DPF switch in OFF position, in hopes of only doing regens at Lunch or after feeding is done in the afternoon. THis morning we found that by putting switch into OFF, we were only able to get transmission to 2nd gear. So, we had to go back to running switch in "Middle" position. District Service Manager was very helpful. He realized that our regens were not working and helped us with our issues. Thanks for the help, I'll keep you updated.

Who are the One Call People?? Are they with Mack??

We have 2 new 2009 Mack GU7 13 model straight trucks. They have mixer boxes on them for feedtruck operation in our feedlot. They have the MP7-405M engines. We are having a lot of truble with having to regenerate or "burnout" once to twice a day. These normally take 30 to 40 minutes to do. When you do 2 or 3 of these a day, production is slowed considerably. Due to the stop and go type of running... our feed trucks can not maintain a constant speed for a long enough period of time to do a regeneration on the go. Does anyone know of a solution for this problem?? We are very fed up with Mack on this problem..... they pretty much have a "Don't care!" attitude. They have not been able to help us with a remedy. According to this site: Mack offers 2 different DPF systems. Fleetgaurd and Emcon. Appears that the Emcon system would work for our application. The Emcon would allow us to do a regeneration while on the move. But, according to our Mack service tech. The Emcon system is not available on our model of truck, it is use more in the cab over styles popular in the trash industry. Can any Mack service personel out there help us with this problem?? Or anyone have any experience with these regeneration problems? Please help!! We are fed up with this problem Sorry, for the double post.... my other post was not getting much attention. Thanks.

We have 2 new 2009 Mack GU713 straight trucks. We have mixer boxes (feedlot) on them. They have the MP7-405M engines in them. We are experiencing a lot of trouble with having to do "burnouts" or regenerate everyday or 2 to 3 times per day. Due to the stop and go of our feedtrucks, we do not generate enough heat or constant speed to do the burnouts on the go. Therefore, we have to stop for 30-40 minutes to do a burnout, which slows the feeding process considerably. Does anyone have a solution for this problem?? I found on this site: That Mack has 2 different DPF's a Fleetgaurd and a Emcon. Sounds like the Emcon is the one that would work best for our application. But, according to our Serv. Tech the Emcon is not available on our model of truck. Even being able to do a burnout when we want to.. not when needed would be a improvement. Any help would be greatly appreciated!!!
