    The fuel supply line runs up the driver side of engine but the fuel injector lines are on the passenger side and there are 6 of them. They screw onto the high pressure EUP pumps and then go over the exhaust manifold into the the side of the cylinder heads. They are know to leak and catch fire if reused on the AC engine. The same fuel line is used on the AI engine but they never seem to catch fire like the AC engine

    Fuel injectior lines every time. I've personally seen at least 6 engine fires on the 2004-2006 CH/CHN and CX/CXN trucks with the ASET AC engine. The injectior lines are a one time use item. Mack even has a video on them on installing them and all the techs had to watch it

    On the AI engine the 427 and the 460 use two different turbos, unknown what series they are. On the ETECH (not CCRS engine) the 427 and 460 use the same turbo part number and it is a S400 series.

    Yes , I see the writing on the wall, it's time to get out, at least at the dealership level. Fleet maintenance is where it's at if your gonna stay in the field.

    Yep , been gone 4 weeks now.

    I believe Mack had us pulling the floor board d out , then pulling the REPTO cover off where you could see the bull gear. If your looking at the back of the engine it's the round cover on the flywheel housing to the right , above the trans , it could also be the idler gear that runs the power steering/fuel pump. You can pull the power steering pump off and check that gear as well. I don't have access to the Mack service bulletins any more or I could send it to you

    Was it at a real Mack/Volvo dealership? Could be anything from a turbo to DEF pump to Nox sensors to software update. Without the Tech Tool program and the latest service bulletins it's a shot in the dark.

    It's 5years/100,000 miles on emissions now. That's the federal mandate warranty. When I did warranty ( up until 2 weeks ago) the standard engine warranty is 2year/250,000 miles. If the farmers, dump truck guys and garbage trucks stayed under 100,000 miles and 5 years , emissions was covered , even injectiors/cups and turbos.

    I am no longer working at a dealership. Due to high turnover of employees at dealerships and the fact the "Grey engines " have not been built in 10 years, most dealerships have no one to do the programming on the older ECMs . It's really tricky in swapping VINs and ECMs and programming over the original files. There is no one left at my old dealership that knows how to do it. Now if you had one go bad they could probably program a replacement but even that would be very time consuming for them.

    I don't know , they look exactly the same as each other.

    There only 3 different EUP part numbers. One for the early ETECH. One for the ASET AC engine and one for the CCRS and ASET AI engines. HP ratings don't matter regarding EUP's .

    My fist thought Is clutch sliping. Does the clutch have any free travel at the pedal

    There is a bulletin on the harness rubbing on the air compressor on some year models with the MP7. It causes random injector faults

    All of our new GR's have been coming in looking like the old GU on the outside as of now. We have a special order Pinnacle that will be here in a couple of weeks . Hoping for the updated front end , but I'm not holding my breath.
  15. Mackpro
    Lol, guess what I was doing at work today ?.................yep , cups and injectors. However it wasn't the cups fault this time. 4 of the reman injectiors were leaking fuel into the oil. 3 were slightly leaking around the plunger/spring . One was leaking badly at the injectior body above the head level. This is not the first time we have had this happen
  16. Mackpro
    Actually there are 3 install tools. One for stainless cups, one for the early stepped bottom copper cups and one for the standard flat bottom copper cups.
  17. Mackpro
    Lol , I hope no one really thinks I said that! And a Ezra Brooks, my favorite bourbon this week! Even though it's not a true bourbon ( not made in KY) So many to choose from down here.
  18. Mackpro
    We use the push style on all stainless cups. We use the old style on the copper cups
  19. Mackpro
    On the cup puller , yours is kinda like ours but with out the claw/puller that's on top. The new swedge tool pushes through the cup instead of pulling through like yours.

    I bought a MP8 turning tool off of Amazon. There are very few tools for the MP engines that are not from Volvo
  21. Mackpro
    I made my own rocker arm lifting tool from thick one inch square tubing because , well that's what Volvo/Mack makes it out of. It was easy. I only made the MP-8 style cause that's all I ever see around here. I hope to make a MP-7 one soon. I'm going to buy my own cup removal and install tools but they seem to update the style every 2-3 years so my luck, as soon as I buy then they update the style.

    If this is a non-ETECH engine, check the big solinoid in the fuse box.
  23. Mackpro
    Never seen one melt out like that.
  24. Mackpro
    Check engine ecm fuse in kick panel by clutch pedal. We have a test ecm we throw on a truck for problems like this. As theses trucks are getting older , we are starting to see engine ecm' s go out. The new ECM's are totally blank when they come in so it won't even start until programmed.
  25. Mackpro
    In the last GU's we ordered with Allisons, you can't get the 505 HP due to no big enough radiator to cool both the engine and trans. However you can get the 505 with any other trans.
