So is it an air operated or cable operated?as pictured? The should be a stop on the linkage there ! I believe it’s a sliding gear in there! I have changed the shaft on these with out removing the whole lump but it has been years!
-
Picture 1 is driven off the main box counter shaft and has five selectable speeds if I recall! On a 12 sp trans !
-
E6 won’t handle! E7 maybe for a while! Wouldn’t want to drag much over 500 for to long ! Just my opinion!
-
Ahh good to know!
-
I doubt Mack will not let you have the Xt program not enough cooling will be the excuse or a non Mack drive line will be another excuse!
-
Not wrong just the way you think. I thlnk like you also! How ever when you’re being squeezed for old parts that they are trying to make extinct the writings on the wall!
-
yup it’s deleted so it’s a crap shoot !Takes your chances with this! Hopefully don’t crack the head! Seen so many isx turn in to shower heads by deleting with the wrong programming! Could be Just a night mare!
-
Make sure you check them slaves as v mentioned! Hopefully injectors cure it how ever grasping straws and chucking parts is expensive!
-
Joe you would think it would be throwing a code if the cam was off a tooth at least that’s what our guys experienced! I think he pulled the valve cover replaced the the brake valve! Milkman is likely on to it the delete program is likely causing an issue!
-
7th injector still hooked up? engine brake valve sticking? half stuck? just shit to think on! If the engine brake is full stuck the engine will start then die a soon as oil pressure is established ! If its part on will run rough and still be fueling! smoke! we had these valves faulty right out of the box ! Just sayin!
-
Is it throwing up codes ? on the dash! these have synco issues in certain gears 7 th if I remember correctly! does it have 2 speed reverse?
-
Me too ! 🤣 That said the vgt could be sticking not uncommon even when not deleted! remove the control motor and check if the control rack is moving smoothly! DON'T break the bolts! 😅
-
With FIC module would make it vmac 1!
-
HOW????????? you answered your own question Joe! her oldest is a drug dealer,
-
Exactly! You can triple the HP on a E9 But how log will it last is the issue! the E6 as Paul stated there even at 285 maxi dyne was susceptible to this they did make a 315 thermal dyne as stated before in another thread there was a reason the E7 came along! sure you can turn it up but DO YOU Really want to?? If you want to keep your toy alive just leave it! in my mind A half turn on the screw is all I would consider myself ! You don't want to be getting your foot into it for any serious work thou !
-
THE LIMITING FACKTOR ON THESE IS THE ENGINE BLOCK! 300 MAYBE ! Just my opinion not a fact
-
It some times takes a test drive to work the air out! Try it!
-
How is the oil pressure with your foot on the throttle held At 650?
-
In my mind there should be no trailers running around with out Spring brakes regardless of year! Same as tractors with spring brakes on only one axle which is still allowed by the way! You can always tell a cheap truck build if it was build with only one set of spring brakes it was a bottom of the line build! BARE MIN spec!
-
be wear ! The selco valve that Joey posted there comes in two versions not sure which number joe has posted there how ever! One will release the brakes on push of the button while it fills the tank / IF IT FILLS THE TANK ! And the other requires the tank to fill before the brakes will release! the later is the best one to install otherwise your trailer can run about with no air in that tank and you would never know! Not a safe condition !
-
Loud squeak / squealing when I set my parking brakes (pull out valves)
fjh replied to itsJC's topic in Air Systems and Brakes
Joe may be right how ever You have a warranty use it bro ! Let the dealer identify it for you! Many times there is a quick release valve on the back of the cab on the emergency line! -
.Sounds to me Mp is on the right path ! Don't think the EGR block is doing it The egr should be throwing a code for mass flo out of parameter! this shows up a few KM after you block it ! Your first boost drop out complaint is pretty exact and some of the other stuff on the list as well there as well! worth a shot doing a reflash! Something may have got corrupted in the program somewhere! (not the first time!) Also if all else fails check the ECM plugs for coolant wicking! relatively common on the older chassis! just something to look at!
-
Try pulling up the blink codes as stated! You will have a mass flow code . How ever are there anymore! For other things! ? Engine speed? Vehicle speed?cam position? These all could make it stumble! I once blocked an egr valve on a customer truck it ran in inhibited for 1.5 mil kms! Not saying it ain’t a problem but…….it was a 2005!
-
How’s the air filter? Cheap and easy stuff first? These filters plug up fast!
-
Well we can hope for is a good out come on this! If it is indeed a loose bull gear it can get real pricey and a deep hole to dig out of ! Alongside all the other crap that can go wrong with this newer stuff! The only saving grace is it has no def system!
