mp7 405 info

Looking at a 2007 MACK GRANITE with MP7 that does not run. I am told the timing gear is out

need to know how big of repair this is.

Here at our dealership its the most hated repair to do.  We now pull the whole engine and it make it much easier. If you can get the truck super cheap and buy a engine repair maunal and do it yourself it wont be to bad. Labor is the killer. If its been run to the point where  it wont run anymore then then engine is probably full of metal.  We are doing a older MP-7 now like that  and its going to be around a 15 grand repair and the truck is not really worth it. Thing is with the MP engine, if your at 300-400,00 miles on the engine,  a  $15,000 ( parts and labor)  massive  bull gear failure repair is probably worth it. If the engine is 600,000 miles plus Id drop a $25, 000 ( parts only)  Remack engine it it and be done with it. All this is if your going to keep the truck and use it to the point of getting your money out of it. But remember , if you got a $25,000 truck and you drop $25,000 into it, you still got a $25,000 truck. I have seen Macks as new as 2012 being junked/not repaired after massive engine failures. Its a disposable world out there now a days.
