Yup I agree with Tech ! Also Its unfortunate but in that era is the year prior to Egr They were struggling to meet emissions Targets And to do so they were being stingy with fuel ! We had a lot of power complains back then, we even dynoed 460s that were putting barely 360 to the ground And they would NOT Fix it! We live in steep country here and need the ponys to get things up and down mountain sides anything less than 500 hp is inadequate!The V8 or Mp ten was the answer for this However they saw fit to remove these from the line up!

E7 no egr E7 aset and AI are both egr engine’s

long as it cleans up when pulling I believe you'll be ok in that department! i'm Thinking the same as milkman Is likely the rad or the fan hub by what you discribe!

The computer Will likly show a bad pump not the injector! u still may have a bad pump if you changed an injector! just sayin

In your case remove the valve cover and check for broken rocker shaft bolts! Just my opinion! the new engines had an issue in this department !

Yup Nice install! 285 or 300 as stated!

To Late now its Spilt Milk! The Gas companies here where I live advertise on tV all the time ! CALL BEFORE YOU DIG ! I think that applies Here!

Like everything else ! mother Volvo screwed up the Heavy haul now the light haul ! Middle ground is all that's left! Oh well I predicted the mack Brand would RIP after the tenth year And we still going ! I was wrong ! even thou the mack cab is really all that's left, the brand is still here , However shallow it may be! Might see another ten years who knows?Once the cab changes that will be the END! Parts are drying up for the old stuff and even the newer stuff!Tough to predict the End BUT Its coming unless Scania or some one buys in ! Highly unlikely as The Volvo influence Is Deeply ingrained From the parts system down or up whichever way you want to look at it! 😡

the problem is likely inside the bell housing

Its likley the clutch actuator is leaking down and is not operating the clutch properly Either a leaking hose or or the bellows has a hole!either way its pricey! and you likey have to take it to a dealer!

Yup remember everybody is saddled with the same rubbish to add on to meet the emissions , Must be some other stigma! ? Maybe the VW People Are Evil !?🤪

Also the supply pumps can fail ( Fairly common) is your oil level staying normal or rising !

new style lifters are of better design the original lifter had the hard surface silver soldered on the new style seem to be one piece these never or rarely fail !

Check your oil pump I’d replace all the lifters

We access thru our dealer portal you may not have access to that on your set up not sure

so likely the 285 hp then

If you have a mack logon at your location you can log on and go to this section ! Case based reasoning ! They have collected all of the field repairs and fixes and compiled them for guys to shoot for when having issues with this and other stuff Its one of the few things that they did right with the program ! as its not all theory Its fact base repairs Done by real people not dreamed up by someone whom has never turned a wrench!

My opinion you have a 285?

possibly ! have a look It could be anything from 275 to 350 what trans does it have? If it has a 12 speed behind it ! will likely be a 350 ! if it has a 8 or 9 0r six speed it may be a 285M 300 M !

e 6 it has side covers behind the fuel pump there is a tag on the rear valve cover

Rd800? Maybe 18000 is a heavy axle! Flat metal fenders?

Dito

Good Job Barry really like it! O well I tried after almost a month I had to change back to oem ! Found I didn't care for the dark mode But Keep up the good work buddy Can't hurt to try things!

My first thought is the accessory relay if you turn the key on and you don't hear a click in the the dash I would check there first!

Fuller would be my pick for all of the reasons above the main one being cost of repair! The Volvo people are pushing the m drive and want all real transmissions Mack fuller or otherwise, out of the picture! So they a gouging on the parts end to make it not worth rebuilding or repairing any thing real Mack Or fuller fuller is far cheaper on the repair side as they. We’re the dominant trans for years!
