    I ordered a synchronizer kit to fix some of the worn parts while I had it out the wanted some numbers off the low range hub and the vin they sent me a pai kit 806803 it seems similar but a few things are different did they send me the wrong kit if it’s right does anyone have an installation guide or something for it I ordered a manual but it hasn’t arrived yet btw I haven’t tore into the power divider yet hopefully this fixes it but I have my doubts

    I haven’t got to the power divider yet but I understood what you meant

    No drives normal it never did this before loaded probably 65k gross pulling a hill in high side made a loud grinding noise for a second then at the next stop sign did it in high side gears getting rolling then on the the hills if I got into it .it got lots worse as I kept going this was all in 30 miles or so no problems before this

    I pulled the drain plug out of the power divider nothing other than oil came out how do you get to the peanuts first group of bolts behind the front yoke .does it come apart for inspection and go back easy with out special tools
  5. dieselfuel007
    How would I go about checking the power divider out to see if it has issues
  6. dieselfuel007
    Tires are new all look good
  7. dieselfuel007
    Well it really sounded like it was in the transmission hope it’s not the power divider
  8. dieselfuel007
    The fork looks like new there is probably a 1/16 gap between the fingers and the ring it runs in should that be tighter? and the clutches all look I’d go for a reman trans but we are getting rid of the truck.If I put a synchronizer kit in is there anything else not in this kit that could be causing my issues if all the other parts in the back case look good

    When it pops it’s like it pops out of gear rpm’s jump you hear gears clash if you let off it grabs ahold again until you apply load it’s not that I’m afraid to put the synchronizer in I just want to be sure it’s the problem

    Yep mp10 titan

    No it’s just in high side I don’t have a power divider I’m just concerned about the low range hub being chewed up and everything on the high side looks fine range shift fork back for high side forward for low is that correct
  12. dieselfuel007
    I have a Mack td713 and I was driving the other day and it popped while pulling a hill and it would do it the rest of the way back anytime you would put it under a load in any high side gear so after reading on here and talking to my dealer we checked the shift fork and the bolt was snug .So we removed the transmission and removed the synchronizer but all the high side gears look good the inside teeth on the low range hub and it’s opposing gear are chewed up pretty good will these have any effect on high side or are there other things to look for

    Well I’ve finally had some time in the shop swapped ecm with another truck and put the ecm from the truck with the miss in the other truck neither truck run different with the others ecm checked fuel pressure it seemed good at idle and at 1600 while I was at my dealer I picked up a fuel pressure regulator/check valve instantly upon start up could tell it run a lot smoother it was on the job today driver said its way better thanks for all the help

    No I don’t have a code reader for Mack
  15. dieselfuel007
    I will clean these grounds I’ve cleaned the engine ground before but I will do it again where is this ground breaker in the bulletin and the ones on the dash?if there isn’t a lightning bolt on the dash will it retrieve this code if I use the cruise control or do they have to be active to do that?
  16. dieselfuel007
    No that’s what’s strange I don’t recall a lightning bolt coming on in the truck when it does this I’d don’t have a lot of knowledge of how the system does it’s diagnostics if it had a bad wire or a wire grounding out should I have a lightning bolt?
  17. dieselfuel007
    If these wires are grounding out at the eups would there be a lightning bolt on the because it doesn’t have one on it was the dealer for three weeks trying to find it
  18. dieselfuel007
    Dealer did all the work with the eups but I will take a look at the wires
  19. dieselfuel007
    Yes it’s got a miss when idling it doesn’t really come and go idling it’s kind of like if you take off at one stop light it’s missing really bad next one not so much it’s obviously down on power as well it really seems electrical to me just because it’s intermittent but seems to be more frequent than it used to be where is the best place to check fuel pressure
  20. dieselfuel007
    We have a 07 granite with a 370 and t310mr trans it’s had a random miss that’s been getting worse you run it hard loaded in town that’s when it’s the worst when it cools down it’s not as noticeable sometimes it even nearly goes away almost instantly we’ve changed nozzles and eups cleaned engine grounds it’s been at the dealer they can’t figure it out I have a 05 granite that has the same engine and transmission can I swap ecms to see if that helps or does anyone have any other ideas
  21. dieselfuel007
    Yes my dealer told me to clean the engine grounds when it started but I’ll revisit it and read your posts
  22. dieselfuel007
    I’m working on an 07 granite dump truck with a 370 engine it’s low miles at 210k and it’s got a miss when taking off at low rpm also when pulling a hill but it’s intermittent our Mack dealer has put all new injectors ,lines, eups ,and adjusted the valves before we did this work it had some injector codes that would come on from time to time now it doesn’t there not sure what to do now they said run it till it gets worse
  23. dieselfuel007
    Well I think we’re gonna pull the trigger on the truck talked to the owner sounds legit so I’ll guess we’ll see kind of makes me feel like a traitor to go for a truck without a grey motor
  24. dieselfuel007
    Well it’s sounds like it runs as good or better and I’ve got really good dealer support in my area do they have the low end power of the grey motor trucks
  25. dieselfuel007
    I’m looking at a 2007 granite with a mp7 395hp we currently run grey motor granites 370 and 427 I’ve never been around any of the mp7 how will it run compared to our grey motor trucks all of these are tandem dump trucks
