Neo, I ordered the service manual for Midliners, and should receive it Tuesday. I will do my best to keep up with you on the 3 post's you have, and send pic's and info accordingly.. I still think its easy to find the air leak when you hook shop air to the truck. I would un hook the air supply from the compressor at the tank. Install an air line coupler into an open port that may have a plug in it, or install a 'T' fitting behind an air line that is coming out of the tank, then install a coupler into the 'T' and reinstall the air line. this way you have a test port, or a port to air up the truck, for other reasons. once this is done, the air compressor line that you removed from the tank is set aside and a plug is screwed into the tank. now you have isolated the compressor and closed the the system from the tank outward. put shop air to it and then crawl around and find the leak... I have a couple of air nipples screwed together for this type of testing. jojo

That's why I said that others may shift it differently, there own way.. I did a bunch of combos in a Mack 12 speed, and then when I got into an 8LL,, it was less shifting, but still a great tranny.. jojo

I think its more for ground work on sites... when you are very heavy or stuck or in tight spots, it's a starter gear... jojo

Legalizing pedophilia is next....

I was taught that you can select lo-lo, then shift from lo to 1st, then split 'up' while in 1st. and shift the rest of the gears normally, however, I bet there is a few ways to shift this tranny without over speeding a gear.. This is my favorite Eaton tranny... jojo

This Just IN !! 1 Soldier and 3 civilians are hurt in Ukraine, from Russian artillery.. Here's the Kicker..... Kamala is on an emergency flight to Europe... I thought the real border crisis was a bit more to the Southwest of another country ??? I guess I was not paying attention very well... Jojo

Neo, It seems to me you have 3 threads on this issue.. in this last post you said you CAN get parts for a Midliner.. if you CAN get parts for youre Midliner, then you are sitting on a gold mine... I have a Book coming my way, if there is info in it that you need, I will try to share it.. I still think you can remove the old air management system and mount a small air dryer that will have the purge valve in it. as far as the unloader valves, those should be in the air compressor head.. jojo

that post is 8 years old....

I guess I should have figured you did.. Jojo

I only saw a few of these and they WERE dissconnected.. jojo

yes RPM/TDC...

ok.. gotcha.. well if I have any info you need in my books, I can take pics and send it through P.M. or text... jojo

the wires on the truck side of the plug tend to rot and break down.... a gentle tug of each wire up the harness in different spots may reveal a fray. hopefully it will just break and then you can fix it an roll on.. jojo

ok, how about the sensor in the lower left flywheel housing? around 8 O'Clock ?

Sweet... thanks for posting the fix... jojo

I dont know if this will help you, but I buy manuals from a website called: "My power manuals.com" (one word) I have about 12. all are engine books.. instant downloads, low prices, and I put them on 2 C.D''s and load them onto a laptop that is in my shop, then put the C.D.'s in a case in my office, in case I need them again.. good luck, jojo

ok, on the firewall may be a black ground breaker next to the starter relay.. I think you have bad ground or grounds

check the accessory relay in the dash, you should here a loud click when you turn the key on.. find that relay and clean and tighten the contacts... jojo

My guess is you have Robert Bosch electric injection pump.... If so.. when you are back to the yard, while it is idling, check the quality of the pins in the gray deutch plug on the governor housing by wiggling the plug and its wires at both ends. gently pull each wire as if you were trying to pull it out of the plug. I have seen many times were the pins get loose and sometimes, one will slide in the plug and barely be touching. especially if the plug has been repaired before or is not secured in the clips with zip ties... jojo

what does the tag on top of the front valve cover say? the part number starts with '11GBA'...... jojo

Been there done that,, at least I made a few people laugh... jojo

when you buy the injector 6 pack it comes with the correct cups. the engines head accepts them.. jojo

5/16"....... 3/8" would be great. jojo

here in N.C it's 2 years also, and they will suspend your liscence if you dont get the card re-newed.. I sleep with CPAP, so mine is 1 year.. even though I am not employed as a driver anymore. jojo

Mech. I know what you mean, and TJC.. drivers stare at their phones more than they do the windshield.. and if they are looking through the windshield, they are only looking over the edge of the hood.. I dont know why the "Smith system" is not taught anymore, Sometimes I wish they would post signs with the "Smith system" on billboards along the highway.. Not on one billboard, but on 5 individual ones so they arent trying to read all 5 at 80MPH... Mech. I have only a few years in a tractor trailer, running the East coast, I have driven through Hartford on I-84 about 100 times, on my route from (P.A. to Maine and back) maybe a bit less, dont remember,, but what I do remember is how many people changed lanes so often and would just go from left to right, or even right to left to grab the next exit, in a flash... and when the highway opened up to 12 lanes it still didnt seem like enough lanes... it's been over 5 years since I drove through there in my 4 wheeler.... and let's not forget I-290 in Worcester M.A. I always called it "The Worcester Raceway"... jojo
