There are lots of tsb on this subject ! None on F**kn injector Cups On E7! Granted the Volvo turds screwed up the service bulletins like they did to the parts system ! probably hid them some place! Now I think on it these guys where his truck is fit right in !😡

I'm Sad that there are Shops that impersonate being Mack dealers some times! but that goes with this generation of people that have No integrity No concept of pride in workmanship ! Is Just a sad state of affairs ! Depressing to See!

Get The Truck out of that shop ! The more I read the more I believe you need to RUN! THEY ARE CLUE LESS! and full of BS!

as Joey Said ! ok... too much to absorb.. stop them, and pull the truck home.. the injector cups on those engines dont crack. I have seen over the whole time I worked on these! injector(sleeves) not cups leak MAYBE twice and never internal !And apparently you have Two leaking NOPE Don't think so ! Get the truck out of that shop! They are not real Mack oriented they got Volvo brain! I have seen where the wrong sleeve was installed in the wrong head coolant leaked out the injector line! These can be replaced in frame IF they are leaking! But they aren't! Injection lines leak yup Fuel ! Tow the truck it would be wise to get the hell out of there tow it to joeys if you have to It will be a way cheaper and it would get fixed proper! And another thing I would suggest if you have disturbed the rocker assemblies replace the bolts there were issues at one time with these and you want to start fresh there ! Joey will likely get get you talked thru the coolant push thing here! another embellishment I read was High liners That never happened either! low liners in the early engines yup ! but not on AI or AC Get the truck out of there! this engine wasn't One of Macks stellar builds but it didn't have any injector sleeve issues to speak of! They were guilty of trying to make it Eat Its own shit just like all the rest due to the emission rules! extra heat to deal with bla bla bla !

Yup Joey will take that 😂

Injector orings was another one I used to horde them when V8s were popular! We did head gaskets by the dozen for several years till they finally got a good handle on the gasket issue! 😁 I tend to pack rat stuff anyway, Might need that some day ! You know!🙄

its hard to believe anything you see electronically these days with this AI Crap going on! They tell you one thing and the exact opposite is going on or worse! This post could be fake for all I know! 😡

I used to squirrel away various parts in my tool box bottom drawer that our parts guys seemed to have a hard time getting saving them from rebuild kits ect, Trunnion inner washers was a common save as not every job was worth using them!

yup noticed after i posted ! 🤣

amen bro absolutely no clue! No work ethic ! May have to make your own offset key 😂! Volvo Turds want the old stuff to die so they can sell more junk to people!

Piston cooling probably started as they were thinking on adding more ponys to the build, morphing up to the 237- 285- 315 I know when they went to 350 they added steel webs between the main caps ! Just before they started using the 4 valve head!

If you suspect the shut down relay swap it with another relay in the batch there remember the one you use so you can replace it !

If there are wires for the torque limit switch they will be towards the back of the trans likely tied back in the loom two wires! if it has a mack trans the switch is located on the back Cylinder At the top! Not sure if they use it on that trans how ever the the wiring will likly still be there ! I have NEVER seen a Spicer trans in that model not sayin it isn't possible usually Eaton fuller Or Mack! Spicer did clone a Fuller trans at one point so anything is possible!

Did you try what Joe h posted ? maybe you should?

wouldn't want to pay a middle man ! Me and Joey want to clean up! Make the big Bucks! He wants to retire ! 😁

Criminal ! one 7018 welding rod 50 cents / one 6 inch by six inch piece of 1/4 inch plexi maybe 3 dollars Plus 3 dollar 100% mark up ! Worth 6 bucks! In materials Bit of sweat equity for etching ! 50 dollars would be reasonable ! $300 Not so much! We should go into business making these we could clean up sell for 99.99 ! You could retire from building engines! Become a door to door piston squirter aimer salesman! 🤣

Yup its not running long enough to even build O/P ! not an O/P or Low water issue! Do the check engine procedure as joe explains there!👍 60 seconds or so would indicate a sensor ! Note I have seen stuck engine brake sols cause this on MP engines I know that this is E7 how ever don't rule out anything! Also check the big round plug at the fuel pump un plug and replug it together several times it may have loose pins!

YUP! If works don't fix it! Same rig I used for years as well Not sure much changed in that department! keep it simple!

Yup took fan belt off today get one tomorrow fight it back in! Drive seized to the pump shaft not unexpected!😡

Nice thing with the e6 you can use cloths pins to hold them up! While the side plates are off!

Nice job buddy! Pop that b housing pan a front cover on and your done! Or are you building a complete?

Joey what do you use to target the piston coolers?

I like the liner mock up tool ! I made one exactly the Same years ago when E7 came out great minds think alike buddy Never had a liner installer always used a bfh and block of wood for that!

👍

Well the Friday parts guys are refunding my cash as they could not confirm what cylinders are on here and are to expensive to send back pretty descent of them ! I did a little more research and was able to figure what cylinders are on there and ordered thru Amazon ! So if anyone needs some Cylinders Brake Master Cylinder D141779 D136837 for Case Backhoe Loaders 580M 580K 580L 590 ! I got em!😁 Thanks Josh ! Ya I can get the floor out real easy its a pc of stainless just chucked on the floor I'm suspecting some one already has been fighting with this issue before I bought the machine hence the stainless on the floor hopefully we can get to the bleeders from here looks tight and my fat old carcass ain't getting at them! I have an eager young apprentice that is going to dive in there and give it a go when they get here next week I HOPE! Wish me luck that these ones are right ! 🙏 And Joey thanx for the heads up ! I'm tryin to Deal with places I can get to with out to much political interference due to import fees and BS Im avoiding using sites I'm not familiar With!
