Paul the lever is all the way back! the 3 point functions with no load in the shop the three point will lift a decent size log when the tractor is in reverse ! When you select a forward gear in first and low and let the clutch out it will drop the log and you now have no traction to move it! a real odd situation in my mind! My davey brown wont balk at doing this only I have no counter weigh with davey it has you looking skyward ! The furg has a loader more weight on the front! I 'm wondering if the valve block is shuffling in the bottom and bumping up against the draft control lever?when in a forward gear!

So another issue has surfaced with the massy here the three point hitch will only lift weight backing up! Soon as you pick a forward gear and let the clutch out to move forward the load drop s any ideas on this!

Can you work its ass? Running at an idle is not the greatest!

Stat first 150 to cold! How long are you running it? need to get it hot!

WELL ! Bet you slept well last nite Joey! 😅 Obviously the shop doing the job, did not, if they care! Like Onyx says done one you done ten! How ever again this comes down to experience attention to detail and patience! Also did these guys confirm the cups were fubar! was there evidence of the injectors dancing , carbon build up,cracks etc. Did they follow all the steps did the use the magic grease on the seal? ! There are lots of ways to beat the book time skip the tune up portion of the job bla bla bla ! that said do you want to be the guy that's doing it twice? Micro cracks on the injectors is quite common did they re use the injectors ? Likley! These arn't your garden variety 400 cummins that any jackass can replace an injector! they are temperamental you have to pay attention on how you work on them mainly to the half baked fuel system design ! SO Follow procedure and things should go ok AS long as you don't miss something !They changed from the copper cups to stainless how ever it only half assed fixed the problem ! The design is flawed as I have said before ! How ever it is work for people as long as its done right! If everything was perfect on these, guys like Pro, Onyx wouldn't have a job! If these engines had a proper fuel system on them they would be bullet proof! And they wouldn't sell any parts! 🤣 also if it weren't this problem I'm sure something else would come up!

Yup get on it!

Yup same to everyone here happy year folks ! Joe you’re doing the right thing bro stick with what you know! You need to embrace this new stuff and sort of believe in it! Don’t know about you but myself ! I don’t! It’s Too fragile and temperamental! 😂

Yup keep up the posts! Un fortunately It may have been worth the wait to go to a dealer! As mentioned its its best to replace injectors and cups for this very reason ! Doing it twice ! Same as doing it your self! So much tinkery ass shit to be aware of! Constantly moving goal posts!

Keep us posted!

Onyx! You are Totally correct! (Hate to admit it 🙂) Crying over spilt milk! Got to get on with some sort of fix here if We can ! So again! from my side walk super intendant point of view! I have heard this compliant before! I remember the guys checking for boost leaks ,exhaust leaks , another situation is the the 7th injector fouled (they replaced that )and the Turbo starting to stick if I remember correctly also the diff sensor clogging opening the egr valve to much to compensate for the clog! in turn polluting the cat with more carbon hence a necessary P-R in very shot order! point is something up stream is likely causing the issue just got to find it! Look for any broken intake bolts just below the front where the EGR comes in , a crack in the intake manifold in that same area .just look for stuff you can find yoursellf! I'll refrain from mentioning all the pricey shit that could happen here and focus on the semi cheap and easy stuff! I 'm sure Onyx and pro will set me straight here but you got to try stuff and look for stuff your self at times ! Another place to look for leaks is the flex from the turbo to the cat they crack a fare bit! The more expensive stuff like engine brake slaves protruding causing an in complete burn , injectors going bad Creating soot , turbo sticking . Long list ! Need to start ruling out stuff!

Yup it’s a constant battle! This Volvo outfit is organized like a shit fight no foresight ! The parts system sucks you got to be a guru to run it! You need a degree if want to run it! And still can’t find stuff. There was a reason for prefixes in the part system the Mack system was way superior to the current Volvo rubish ! Even us dumb mechanics could find parts with the old system!

Have you changed you air drier cartridge lately? If not do so! Wet air can take out the hi module! This is just a comment not a fix for your issue! It all could come down to where you were driving lately long drives heavy loads keep the regens away! As stated!

My Davey brown had a clutch switch!

Yup 👍 good news thanks for posting the fix!

Don't rule out the starter as Glenn mentioned!

Rule of thumb ! If the engine starts up clean running on all 6, suspect electrical. if it stumbles to a start suspect air in fuel! Could even be something as simple as an ignition switch !

They will be after market! How ever most of the mack sensor parts are made in Mexico ! Pick your straw!

They all do even stock turbo? The lengths are different!

I don’t know where you live how ever if you got a local fuel shop you might want to check with them! Also mak sure your air filter is clean this has caused issues in the past specially with a high output turbo and fueled up engines! In the land of oz the v8 was or could produce 650-700 hp we installed an ozy turbo on several trucks here and as your observation 35-40 psi boost was not uncommon! Just tweaked the fuel to the need! Note the drain tube was a little different so beware!

Could be a Differential issue

With the engine running I would suspect lots of bloby at the draft tube in the low compression dept! Im sticking with my tank vent or or his suction line theory for now Joey ! Just running with his symptom's at the moment! The lost of prime makes the most sense at this point! In the first statment only in the morning next statement after ten minutes of shut off! Rule of thumb ! If the engine starts up clean running on all 6, suspect electrical. if it stumbles to a start suspect air!

Yup cheers to all Bros !!

So keep us posted on this interesting issue! If the issue persists after the suction Lines are replace check the tank vent!your description really describes the scenario to a tea! Vacuum created in the tank sucking the fuel back when shut off!

Yup
