Like you mentioned use a dumbie input shaft and pilot bearing on a vice?

Worth a try! fly wheel run out can be checked with fly wheel on the engine! with a dial indicator! balance has to be done by a machine shop or by the dinosaur method I have stated just somthing else to check!   (leave no stone unturned!)

Highly doubt the clutch is hurt!

Think past conversations will include you as far as low oil flow to top deck of engine. Keeping in mind oil powers your jake. Are you aware of which update remedies you have already, or someone previously, installed?

Ageed here your issue is not uncommon!  oil preasure / flow is the key! does it have an external oil source Kit on It!

Hi did anyone think to check the balance of the flywheel? It sounds like you have had many clutches if so. then if the fly wheel has been surfaced lots or even changed  it can change the balance of it just somthin  to think on We once chased an issue in our shop similar to this  on an E6 it turned out to be the flywheel! found it by mounting our input shaft dumbie  in the vice put the fly wheel and pilot bearing on the spigot of the dumbie shaft and the fly wheel would always fall to the same spot like an out of balance tire! ( The wonders of gravity) or frustration of it!

We have 10 or 12 common rail engines running around here for over a year and still have not had any problems that a software update couldnt cure. So far so good!

We also have half a dozen running around here And the same result ! To my surprise  few issues in the fuel system department, we changed a couple of rail sensors so far that,s it That s in keeping with the on going cheapass sensor thing that has always been a thorn!

(May)      have a winner :  we will see!

As for up time ! ?? They talk the talk ,but its the walking they have trouble with! They tend to stumble alot!

If it's vibrating that sounds like injection cups. 

Agree however if you get the wrong eservice guy  this can drag things out. you got to follow their protocol or you don't get paid! Its a rock and a hard place for the dealer! Having said that. it is a 2018 likley common Rail and  haven't estabished  a track record for failure s yet!

Fixed that for ya

YUP Macpro  WE TEND to blame the wrong things some times!  

call a spade a spade!

Try putting it in 1st then throwing the switch!

I agree to that to some extent but I'd bet 10 out of 10 diesel repair shops have the software for Cummins and Detroit which means they can work on any brand. Since Mack is Mack only and I'm guessing there aren't nearly as many as the other brands they'd be less likely to have the software. Not trying to start a war but going by the trucks on the road stats the above statement is likely true but it's not a fact but just my opinion. 

No argument here on this Quote how ever Everything changes when you throw an auto trans in the mix which every one seems to be pushing .They seem to be hell bent on creating stupider people here ,they are providing people with so many conveniences abs atc  vsa  bla bla bla ! Pretty soon you will have  nothing but idiots driving 80000 lbs down the hyw. The upside to that is half of those units will be in the shop having repairs done to all the crap they are piling on these units ! Those will likley  be dealer specific  vehicle ECUs  , As Rockwell pointed out A derate  to 5 mile an hour on 55 mph hyw  is down right dangerous for someone who knows how to drive Just imagine it happening to those that don't , guess the point is that it seems All manufacturers are trying  to captivate everything ! there my be a cummins dealer on every corner but  not always a  KW dealer or a Pete dealer or a Binder dealer and with all the automation  your married !

Just saying 

I would like to point out ,If You do a "tune" you will likely  limit your self even more than you are already The Mack softwear is almost identical to Volvo how ever  From what I understand Unless your a Dual Dealer we are allowed  to see what we have paid for as a dealer !And yes  "ALL THE NEW STUFF" is entrapment You ARE Married to the brand! NO matter what you drive!

yup all the best Barry !

The spec for liner fit in the bore is .002" loose to .001" tight. Liners moving while rotating the engine is nothing to worry about. If they do move, make sure no debris or crud gets under the liner flange. 

If you are concerned clean and dri the bore , I have put a small amount of lock tight at the very bottom of the bore  however I also  would not be too concerned  as stated  00,2 is still ok don't forget the liner will likely swell as the engine warms  , It ran before it will run again! 

Just sayin!

There should be an air filter some where! if not its been removed! as for shifting how long you been driving this?

These are a quite a bear to master! specialy spliting  the 4  to 5 I know of only two or three guys that can split them up and down  in the higher gears with out grinding and it takes lots of practice and experimenting with the engine brake! I have rode shot gun many times with guys diagnosing stuff  !an only two or three could  do it clean and they had a system with the engine brake swithch . I personally have never mastered it because I don't drive em for a living  just wrench em! Having said that you can buy a oring kit and try rebuilding the shift lid That may help! as for the oil don't recall the litre  3 gal  /12 litre rings a bell maybe  .    85/ 90W 

Good luck with it!

Rad is under 16 psi  pressure once the engine is shut down and there is no fuel pressure to counteract coolant pressure It can conceivably push back into the fuel rail coolant is sealed by an oring on the cup! Volvo Has had CUP issues for years and has yet found a GOOD fix!  It is a tad unusual to have your condition however Very possible! and is where the most likely place to start is!

Nope not impossible at all! injector cup issues plague these engines with a host different symptoms! hard start ng being the main ,stalling and antifreeze consumption and fuel contamination !   So if your truck is not equipped with a fuel heater its likely a cup issue or a cracked head!

Not at all strange!

Bro go to the red fuel filter and remove the line coming from the tank check the elbow into the filter is not plugged with shit These tend to collect crap

Thats all well and good as long as you can still work thats the key! UPTIME if you can suffer thru with a little less power until the turbo gets here then great turbos are not cheap to stock and depending on how many failures they have in their area it may not be worth it to have one on the shelf ilies why they order one!

Again good luck

just remember EVERYBODY else is having the same and or similar issues with this new stuff

Mack and volvo don't have the market cornered when it comes to turbo  failures!

Chances are they will have to file an e service The follow instruction from Big brother!!!

And depending on big brothers experience , he may or may not roll the dice correctly  Could possibly be a turbo issue won't throw a code for that. could be a stuck egr valve may or may not throw a code for that!There are several good guys at Eservice  And there are a few ledgends in there own minds guys that may stone wall them Unfortunately,  hopefully they get one of the good ones and minimize your down time! It all depends on who has the balls to throw the right part at it with info provided! chances are its a stuck  turbo issue as it is a fairly common thing!

Good luck to ya! 

in my opinion if the shaft has no loss of motion twisting it  it is fine!how ever it is the inspector you have to please not me!

So much for The MACK commitment to service  and Uptime!

I have some advice There is a kit made to repair the valve once you have the valve repaired leave it in the on position don't touch it ever again  and simply add a little coolant after you change the filter these valves were a good IDEA in theory however  the orings cook to the metal and u end up where your at!

Cummins has had this setup for years didnt work for them either! 

Just an opinion

Sorry !  please provide info year and model of the unit! sorta helps!  Any codes?  Its kinda like telling the dentist you have a tooth ache and not telling him which tooth !

Yup that will be the replacement for the MR once  they have finished wrecking it and the LE!

I'm seeing more and more issues with that M ride spring suspension. Lots of bushing issues.  Mack carriers exploding everywhere as well. I'm shocked. These Mack carriers are dropping like flies.

There will be a redesigned Mack Carrier launched end of 2018-early 2019. The new carrier will go away from single bolt threaded into the carrier housing concept to providing a flat surface on top able to mount the V-Stay with 4-studs.

Is this other than M-Ride suspension (with V-Stay bolt stripping the carrier threads) you are talking about? What part of Mack carrier chunks are falling off?

Mack carriers exploding everywhere as well. I'm shocked. These Mack carriers are dropping like flies.

So apparently this exploding issue was a Bolt manufactures fault A  Single bolt that holds the gear to the spur shaft! threads were cut wrong  or something???

AT least that was what I heard or read somewhere!

I have repaired several of these put (  lock tight on the threads  ) did that even when we used the  good  three bolt design!

Still like that Three bolts design better !   If it ain't broke don't  fix it!
