scdomizio Posted September 12, 2013 Share Posted September 12, 2013 I have a 2008 GU713 with 110,00 miles that already needs an engine rebuild. The rings were broken on #1 and #6 and scratching on the others. Our Mack Dealer tried to get Mack to pick up some of the cost and they refused. The cost is almost $15k. We own 6 Mack trucks from different years and haven't had issues. Has anyone had ring issues with the MP7?

Mackpro Posted September 12, 2013 Share Posted September 12, 2013 Yes on the broke rings and your not yelling loud enough. Contact corprate offices. They should get you in touch with the dealers DSM ( district service manager), he can make things happen. 1 Quote Link to comment https://www.bigmacktrucks.com/topic/32748-mp7-rebuild-at-11000-miles/#findComment-205685 Share on other sites More sharing options...
Superdog Posted September 12, 2013 Share Posted September 12, 2013 I never had engine problems,but had a Mack transmission fail in a 2007 at 480k miles that Mack wouldn't cover one dime on. The DSM didn't help either. In the 40+ years we've ran Macks,never ever did spend a dime on a Mack transmission or rear end,other than maybe a leaking seal. That was over a year ago and I'm still pissed. 1 Quote Link to comment https://www.bigmacktrucks.com/topic/32748-mp7-rebuild-at-11000-miles/#findComment-205690 Share on other sites More sharing options...

ap40rocktruck Posted September 12, 2013 Share Posted September 12, 2013 DSM is the one that said we were on our own. Just another example of mother Vulva tightening the noose on Mack's customer service, along with the future of the brand....The DSM's are limited by what corporate Vulva says. It is only going to get worse, NOT better. 1 Quote Richard MarkOwner / Master Model Maker Industrial Model DesignAp40rocktruck Link to comment https://www.bigmacktrucks.com/topic/32748-mp7-rebuild-at-11000-miles/#findComment-205702 Share on other sites More sharing options...
bbigrig Posted September 12, 2013 Share Posted September 12, 2013 110,000miles........ Yikes! How many engine hours and what application was the MP7 used for? That sucks. I hear these kind of stories with DD15 engines, bummer.

Popular Post rsb502 Posted September 12, 2013 Popular Post Share Posted September 12, 2013 If I had a 110,000 on a new truck and the engine went down, I would park it in their lot and call their corporate office and tell them to fix it or else, after hearing that they were not going to fix it I would take out an ad in the local paper notifiying eveyone of the issue and the refusal to warranty anything, if that didnt work Im pretty sure it would catch on fire in their parking lot overnight one night. 1 3 Quote "Any Society that would give up a little LIBERTY to gain a little SECURITY will Deserve Neither and LOSE BOTH" -Benjamin Franklin"If your gonna be STUPID, you gotta be TOUGH" "You cant always get what you want, but if you try sometimes you get what you need" Link to comment https://www.bigmacktrucks.com/topic/32748-mp7-rebuild-at-11000-miles/#findComment-205728 Share on other sites More sharing options...

MightyFruit Trucking Posted September 12, 2013 Share Posted September 12, 2013 If Mack is doing business like this I might as well by one of the older Mack's and take my chances! I feel for you buddy! I was just considering getting a newer one!

staxx Posted September 13, 2013 Share Posted September 13, 2013 I would just put new rings on pistons with new liners and reuse everything . I have seen very high milage mp7 8 with almost no internal engine wear , the bottom end of these engines are very strong. 1 Quote Link to comment https://www.bigmacktrucks.com/topic/32748-mp7-rebuild-at-11000-miles/#findComment-205773 Share on other sites More sharing options...
scdomizio Posted September 13, 2013 Author Share Posted September 13, 2013 Thanks everyone for the input. I had called Mack Corporate to file a complaint and they told me that someone would get back to me in 4-6 weeks. The company and the product aren't what they were. This a boom truck for concrete that is vital to our business so I didn't have much choice but to have them fix it. I am shocked that with $8k in parts Mack or the dealer wont do anything.

The way it was "explained" to me was that I was over 5 years in service with the truck,which is well and good ,but I still find it totally unacceptable for a Mack transmission to fail with less than 500k and I sure as hell would hope that they would too and want to keep a customer happy.Peterbilt will be your best friend until the ink dries on your check. 2 Quote Link to comment https://www.bigmacktrucks.com/topic/32748-mp7-rebuild-at-11000-miles/#findComment-205989 Share on other sites More sharing options...
rsb502 Posted September 14, 2013 Share Posted September 14, 2013 Yeah don't expect much from Pete, kw is better but its still pa car.

bullhusk Posted September 14, 2013 Share Posted September 14, 2013 I just ordered a new Western Star 4700 with Detroit's 13 liter 470 hp motor, I also ordered another W-S 4900 glider but this time we're gonna get it with the motor (Power glider 575 hp non EGR Detroit) and put our trans and rears in. The rolling glider we did last year so far is workin out OK and the fuel mi for a 575 hp motor is good (over 6 mpg). There was a time I would not buy anything but Mack but they just would not stand behind there product! Why? I don't know! I don't like to knock Mack on this site out of respect to Barry and Watts Mack, but it is frustrating when you try to be a loyal Mack guy and they( Mack PSR) turn there back on ya? I just don't get it??BULLHUSK 2 Quote Link to comment https://www.bigmacktrucks.com/topic/32748-mp7-rebuild-at-11000-miles/#findComment-206009 Share on other sites More sharing options...

Popular Post rsb502 Posted September 16, 2013 Popular Post Share Posted September 16, 2013 I don't think any newer diesels will ever be reliable long lasting engines, there's too much electronics and too much heat and back pressure on them. I still think if I needed a newer truck I would look for an 07 back and just rebuild the whole truck. You can make it whatever you want that way and you'll get better fuel mileage and reliability, oh and no FET. 3 Quote "Any Society that would give up a little LIBERTY to gain a little SECURITY will Deserve Neither and LOSE BOTH" -Benjamin Franklin"If your gonna be STUPID, you gotta be TOUGH" "You cant always get what you want, but if you try sometimes you get what you need" Link to comment https://www.bigmacktrucks.com/topic/32748-mp7-rebuild-at-11000-miles/#findComment-206516 Share on other sites More sharing options...
