    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

    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.

    Never seen one melt out like that.

    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.

    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.

    Double check battery cables as DEF ECM has its own small power wire and fuse right on top of the battery. See if you can read engine hours on the dash display under trip info. DEF level issue won't keep engine from starting. If you can't read engine hours, engine ECM is not powering up or communication issues

    Should be on the top of the driver side fuel tank. Either the sending unit is bad or the wires from the sending unit to VECU Vechical Control Unit are broken which can be a pain to find

    All 2004 and up CH/CHN and CX/CXN have the ASET AC engine. The ASET AI is only in the 2004+ CV, MR and LE and very very few of the last R series.

    There is a service bulletin on the 3-4 code SB221037. I believe it's been posted here before.

    At least you won't be doing regens, several sets of injectors and cups, bull gears DEF injection issues like the red motors. Having seen what I've seen personally with the red engines. I'd take a 2004 ASET AC engine any day over a red motor. Even though I used to think that 2004 AC engines were the worst ever

    FJH, I'm glad I'm not the only one ready to retire out of this madness that is Mack now. Dealing with corporate is getting worse every day. Only thing good is the pay in which I can't complain. 5 more years and I'm out for sure , if I can take it that long.

    At our shop , on our DOT inspection forms , there is no mention of checking for fault codes. However , a state inspection or one done by a actual DOT officer may be different. I have heard of active ABS fault codes causing some trucks to fail some DOT inspections at weigh stations.
  18. Mackpro
    I have done it with the engine running, I believe the parking brake has to be set or no road speed detected.
  19. Mackpro
    With fault code active , turn cruise control switch off. Push and hold the Acel/Decel switch (either top or bottom) for about 3-5 seconds then release, the yellow lightning bolt will flash out a 2 digit code

    A quick search I found this. http://www.trucktransdiag.com/downloads/4gen.pdf This might not be your exact model though. The process is different for each generation of transmissions. I even saw there were YouTube vids on flashing the codes out.
  21. Mackpro
    I believe you can flash out a code on the newer Allisons trans using the keypad.
  22. Mackpro
    All I know is don't take one out and put it in another truck. Causes all kinds of weird issues.
  23. Mackpro
    We have no dealings with anything Allison at our shop even though we sell quite at few new ones with Allison trans in them. We send them to our authorized Allison dealer

    Check the o-ring on the bottom of the engine brake valve where it bolts to the head as well as the o-rings on the tube.

    One year warranty on this issue. There's really not a official bulletin on this but I have some unofficial info from the higher ups that I can send you and explains it better. Message me for contact info and I can send it to you.
