how cool is that twins Im in love Paul

it might have to go out the deep reduction end ? its been a while since I've had mine apart and I was taught you cant split the trans on the truck should be pulled out and stood up on its bell housing I have never had to force these gear boxes apart to work on them it it dosnt come apart or together easy somethings wrong well that was the way I was taught mind you I was not trained by Mack just another bloke working in his back yard I have had my 12 speed apart a couple of times and it was fairly simple Paul

Is it still standing up on its bell housing if not it may need to be Paul

melonreo welcome aboard mate Paul

welcome aboard mate Paul

might be the big bolt in the tail shaft yoke have had it come loose makes a bit of a rattle but not in all gears I think it lets the out put shaft drift around a bit ???????? Paul

WOW I have looked at this thread a few times theres diff ratios I just find hard to believe or perhaps Im just way out of touch you blokes would be having a heart attack with my diffs Im pretty sure they are 5.73 12speed OD and rated 115 ton will get around 3.5-4.5 MPG depending on wind 85 kph top cruising speed get around 6.5 MPG at 42 ton a lot different figures than you all run horses for courses I guess Paul

Well do I have some good news for you there are plenty out here !! It is hard to believe that they were major interstate trucks in there day grossing out 42.5 tons or 85000 lbs doing trips just as quick as todays trucks well almost as quick and they still make them here . Its just goes to show if you make what people want and not try to tell them, what they need you can compete against the cheap imports but they have to listen to what customers tell them they want a recent post thread thing'o' springs to mind about about Ford relaunching a F truck in Brazil http://www.bigmacktrucks.com/index.php?/topic/35823-ford-re-launches-f-4000-at-brazils-agrishow/ Maybe Im not real smart but the car manufactures cant seem to see this in Australia and yet the truck people can perhaps they need to look closer at what other companys do Paul

is it getting power to the small wires on the solenoid or just the big wire ? Paul

yep as stated above you lot are in a mess there used to be a saying once "only in America" that we all used when something amazing happened it still gets used but for different reasons good luck sorting out you mess just many zeros are in a trillion thats a whole truck load thats for sure There is one US TV personality who says "you cant fix what you dont acknowledge" some body on here might need to drop that off to the man you have in charge !!! Also when Im driving down the hwy and I make wrong turn the further I keep going the wrong way before i turn around the longer takes to get back track .Good luck getting back on track None of this is been a smart ass just simple observation from me and yes we do have our own problems here in Australia but man you have got a doozie over there Paul

hey watch it you blokes are gonna go blind soon Paul

thats good to hear the problem solved I dont worry about using the clutch to split just flick the switch and back off the go pedal and then straight back into it if dosnt shift clean straight away you have some other problem . Just a word of warning if your mate hasn't driven one of these and are used to a shudder "road ranger" ur yuck as soon as flick the switch it puts pressure on the selector fork trying to change it were as the the other inferior brand only try to change when the stick goes thru neutral Paul

the shifter rods under the lids might have some surface rust maybe? you can take the lids off with the box still in getting the rear lid back well he will a whole fresh bunch of swear words . Has he looked the air rams maybe there leaking? "O" rings maybe buggered ? good luck with this Paul

that will teach you to fall a sleep congrats some times I fall asleep and when I wake its like a whole new world Paul

my 12 speed has no cooler and as above only pump on the input shaft so cant see how that cooler is gonna work any good ?????? Paul

Mort that all sounds about right to me sounds the part only just more for dropping revs quick with a five or six speed Paul

come on you cant tease us like this must be good you had to keep telling us about it . What gives no name or just keeping it to your self and you no it dosnt count if you are asleep Paul

I can almost hear the GROWL from here lol Paul

Ah one of the many problems I dont have, by not having electronic gismo's all over my truck, gotta luv the old R model such a sweet ride Paul

fantastic not something I would have expected to see just goes to show you dont need 600 hp that people seem to now Paul

Mate all them beans in the last picture you'll be farting like a draft horse Phew lol Paul

well they sell plenty of double coin tyers down under seem just as good as the other well known brands and they have been sold here since the 60's Paul

welcome aboard jnr ate mate welcome I have been known to pull the odd road train and yet I have no idea what your asking ???????? Paul

well I had never heard of this movie so jumped on google and bought a copy what can I say nice truck's from a different time story line never kept princess awake she got to the end and said so what happened I had trouble explaining suggested she watch it again she declined cant make these woman out yet lol Paul

well its what we call a cool power Mack here in Australia looks like a five or six speed trans to me and is that a front diff I see and would that be a 38000 lbs ass end ? looks that way to me but not on camel back dont know what the back suspension is ???????????? I bet you can feel a road trip coming on Vlad Paul
