yes sir.. wish I knew... I will try to get an answer tomorrow... is yours a 613 or a 713? I know someone who is very smart about Superliners..

I have one of these in the fleet that I maintain. I will try to take a look tomorrow morning. I'm surprised Watt's Mack wasn't able to help, using the V.I.N.

ok... the P.O.S. system is B.S. it has a 25 MPH limiter... blah blah blah... Just run an air switch of your own to the front diff, and make it work like they used to not to long ago... the celenoid/servo bank on the left frame rail has the switch in it... f-it... run you own. shut the original dash switch off so the ECU doesnt see it.... now it's up to you to shut it off when not needed... you can put a brake light switch in the air line attached to a buzzer, so you can be reminded that it's locked in, especially if you put a driver in the seat... iv'e done this several times... Jojo

its on the injection pump. the throttle lever rests on it. Ambach pumps have a 3/4" ish long, 5/16" jam nut with a flat head screwdriver head, in the center, Robert Bosch has a a 10mm jam nut on a screw that is 8mm-(5/16") I'm guessing you have an Ambach... What I have done is remove the whole screw and clean it up really good, (I expect it to be stuck)... look at how the screw is set, so you can put it back together close to where it was. you can use the tach as a guide, what i have used in the past, is a hand held photo tach and a strip of reflective tape on the harmonic balancer, something like the d.o.t. tape on a trailer, (white color). I have done enough of these where I pretty much can hear when it's good enough. not rocket surgery, just set it between 600-700... There will be more opinions on this, but it is simple to do. the long screw around the flat head screw is the jam nut. you turn the flat head until you like the idle speed then lock it down.. do you have an engine brake on the engine?

What tranny do you have? These trucks are slow, but deliberate... I'm always interested in why there (isn't enough power)... but never got an answer why they need to be boosted up... Mack's are work horses... I've hauled 120K with a 97' 400 and an 18 speed, 4:17 rears and could pull the hills in Maine where I was driving, did it every week, heavy illegal loads of dirt in a tri-x trailer...Just curious, Jojo

hmmm.... its not behind the shock mount in the frame... I cant say exactly but I thought it was there. the paint is probably too thick and hiding it. wipe it clean and look, at an angle with a light. mabey you will see an impression in the paint.... then break out the 2" scotch pad and buff it clean... jojo

I'm no Gearing Guru..... but I have driven a bunch of trucks with that combination... for me.... they hauled just fine. mabey I'm not in a hurry to get down the road.... 🙃 jojo P.S. I like the 8LL... I would take it over a bunch of Mack tranny's...

it is now better than when it was new....probably gonna pop a wheelie on the strong side when you go over uneven terrain...🤣 jojo

youre welcome, sorry about the hard work you are about to do... you know where to come if you need more help...👍 jojo

Jesus Christ!!!!!!

just curious.... what tranny and rears and tire size do you have? The E-7 can pull really good.... jojo

as far as bypassing the compressor.. you can cap the 2 lines.. dont know if you have the newer (2001 'ish) stand pipe update with the #6 JIC fitting. but you can screw any kind of plastic plug into the ends, even if there is a tiny drip, I suggest plastic plugs because you can destroy them and not hurt the threads on the ends that you will hook back up.... remember no water pump or pressure in this test... you got this... JOJO

should be no bubbles, because air pockets will clear due to removed thermo's... I did this a year and a half ago on a 90 E-7.. It took a bit to push coolant, so I wasnt sure.. then I did my test and it made bubbles after a few minutes, not instantly. front head was cracked between the intake valves... jojo

It boggles my mind, how the Dems said that trump was wrong when he pushed for a quick vaccine, and gave initiative and incentive to get the job done... (as a real boss man would do)... then it got done. then the Dems, say,, Oh hell no!! why would we trust trump, (as if Trump Created the actual vaccines).... then Obama's puppet becomes our fearfull leader, and says he will have 100 million vaccines given in his first 100 days, and he is currently saying that those who dont have the vaccine are a problem for our nation.... (WTF) however,,, if you walk into our country you can go and do whatever you want, and we will provide free transportation. no need to be vetted or vaccinated, because that would be RACIST... I cant believe 80 million AMERICANS voted for this COMMIE.... Jojo

Good luck.... jojo keep in touch

help me with this thought i have.... i hear that Florida and Texas are experiencing high covid cases now. Of course, I ask, how do we know? But I also think its beause our great leader, allowed and shipped, border jumpers all over the country, without a 14 day travel quarentine, to many states to help increase the covid cases.... yes... I know I sound like a nutcase.... but its what popped in my head..... Ok..... Let me have it!!! 🙄 jojo

when you pull the panel that has the cup holders, you can barley see a screw at the top of the top right corner... What i did, was.... i made a flat tube out of card board and attached it to a shop vac. then take a small lenght of 2x4 and pry the duct open, gently and hold it with the block... then take the homemade vac tube and suck it!!! i use card board because it will shred before F'n up the core.... just be patient... you will also see a blue plastic filter thats like a brillo pad.... I have stitched 2 of them together with zip ties and stuffed it back in, then just pull it out to clean it.... not a true fix, but when you get good at cleaning this, the 20 minutes is worth it... another thing you can do after its clean is to switch the hvac to recirculate, or just shut it off till you are out of the dust,, not perfect, but somewhat preventative.... ok.... there will be more and better ideas coming... good luck, Jojo

Its only obvious to those of us that work, and employ workers.... Oh yeah, and have to decide if they are going get a new.... anything.... or pray the old one hangs on for a bit while I fix the house, or the car.... Oh wait, keep my kids in good repair as well... Just my thoughts... I dont have kids, but I have the other things... Just a small working fish in a pond of welfare pirrahnas... Jojo

with the belt off the water pump, there wont be any flow, so the water will be "still" until combustion pressure enters the cooling system... no biggie, its a bit of work to do this test, but a heck of a lot less time than pulling heads that didnt need to be pulled, plus the cost of gaskets and bolts,, and whatever else decides to break..... Good luck sir, Jojo

Utterly amazing!!!

ok... I was told much less than 45 years ago that it can hurt the turbo.... thank you for clearing it up for me.... I have been laughed at a few times about this, guess I don't know what I think I know... 👍 jojo

is there a cap on the stack? if not.... tell him to check his turbo.... and .... yes .... girls kick ass......jojo
