Hello all, I'm looking for a driver side rear cab corner for my 2010 CXU. There are some rot holes that I cut out, and instead of making them myself I was hoping to just weld in a new corner. I called mack and they wanted 800+$ for the whole corner, which I do not need. I only need the small section behind the marker light and under the grab handle. Thanks!

Hello all, I'm looking for a wiring diagram to find where the wires go to from the boost pressure sensor. Truck has no boost showing on the gauge, just 2 dashes like this "--". I feel plenty of boost coming out of the hole where the sensor goes, and also replaced the sensor already. Truck has no power at all, so I need to find where the wires go and hopefully I can find a bad one. Motor is an MP7, Thanks

i have this same issue with my mp7. can anyone be more specific about where to find this wire? what color it is ? anyone have a diagram? thanks!

Anyone have any ideas? Can the truck be derated without throwing an engine light? It doesn't seem to have nearly the power that it should.

Hello everyone, I have a 2010 Mack CXU613 with an MP7 in it. Has less than 500,000 miles on it. I bought it a year ago and have had these issues since I owned it, finally getting around to fixing stuff. In the year I've only put about 3,000 miles on it. Here is my list of problems: -lower power than I would expect it to have. but I've still been able to put 3000 miles on it grossing 80k or more. -boost maxes out at 20 PSI (on the dash) fully loaded with the pedal all the way to the floor. -sometimes loses fuel prime overnight (more often than not) -it always wants me to do a manual regen (I've tried manual regen numerous times, it will complete a regen and light will go off briefly then tells me to regen again) -if it sits an idles for longer than a few minutes it will start to do an odd, off-balance idle. It will stay like this until I bring RPMS up. Here is the list of things that have been done to try to fix some of these issues(that haven't made a difference): Brand new Mack 7th injector was installed, DPF removed and cleaned, fuel filters changed, new boost pressure sensor installed. Any help on where to go next would be appreciated. Thanks
