Heinz if you find one I believe there were two different gaskets don't forget to order the gasket! If its available

If the engine has an AMBC fuel pump You could try and extra Gasket under the fuel transfer pump ! The little pump in the main pump tend to put side thrust on the pump cam and Can change the timing on number one cyl as the bearings wear! just something to try! 🙄

Do to our terrain we could have been still selling Mp10 here it is a brute pulling machine when everything works right! Volvo chose to shut Mack out on that deal! Hope your right about the shim thing stupid idea! The MP8 is set up much better a bit more mechanic friendly !

I've been out of it for a year or two But agree with your assessment mostly! Unless its changed ! What I saw and didn't like was using shims for the set of the rockers DUMB idea! Means a guy is AGAIN Tied to the dealer for a shim kit for what is normally a simple task! Mp8 had normality to it Proper screws and lock bolts ! And aside from the Bull gear failures and Decent engines aside from the cup issue that Should be resolved by now !Of all the new engines the MP8 and 10 were basically Decent engines ! and of coarse the half baked emissions stuff! Everyone is dealing with that junk!

It cuts the air pressure in half so the front brakes don't lock up enabling you to steer! The way I under stood it ! the auto one which yours likley is after XX amount of preasure gives all available air pressure!

Just curious! So Macky Who does your work now if you have other engine or chassis issues?! A lot of dealers won't touch a deleted truck ! Just sayin ! What happens when you have to plug in to check something other than emission related faults !( example ) Say to do injector cups and change Trim codes ? What happens then? just asking! I get haveing rid of this crap however there are other things to consider , just saying Let everyone see the big picture here! I'm interested! I am Not by any means being negative of your choice to delete just would like to know how you deal with these other issues that arise !

Are there an engine codes?

A while back I posted an article on these guys ! Here is a bit of an up date and the corruptness of Our governments both sides of the border! CRIMANLS in charge spewing Environmental BS and not following there own preaching's ! AND Tring to profit by it! Angers the hell out of me! Bare in mind I can't vouch for this not being AI but wouldn't surprise me one Bit! check it out

Bro your experience is welcomed here ! And I believe you will be an asset !

It may be a front wheel limit valve Is there a limit switch on the dash? does it go to the front brakes?

Also something you can try is after you push the seal and sleave on put the flywheel up and on with two bolts and take it back off again before the sealant can set up!And check everything ! it maybe that the fly wheel is pushing the wear ring on farther that the installer is pushing it! A! also as Joey and others have mentioned Do it cold with rtv or locktite or anaerobic sealant !

hoekey junk!

So my point was the first tool Mack provided to do this job was a piece of junk it had four clips on it to guide the ring and did not work well! heat or no heat ! 50/50 weather it worked right! Get or borrow the right tool to do this job and you won't have as many issues! The seal is not likely leaking its likely the wear ring letting oil thru! Just sayin!

we built a tool similar to this MACK REAR CRANKSHAFT SEAL/WEAR SLEEVE INSTALLER ALTERNATIVE TO J-37716 — Ferrum Tools for the shop it pushes the wear ring and seal on in one go and you can install the wiper ring with a small skim of silicone or loctite NO HEAT a much better way to go! The wiper ring can be a real asshole thing if you don't have the right tools! Works on E6-E7 - E9 ! I'm sure Joey must have this in his arsenal of tools ? Just sayin!
