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

mate there are gear box's and theres gear box's I have never heard of it been hard to get parts for a Mack 12 speed and if we can get them here in Australia Im sure you can get them over there easier to drive than a 13 speed roadranger and a lot tougher I no what I would prefer 12 speed every time seeya Paul

we call air start "The Granny Scarer" in this wide brown land Paul

Brocky give us yell when your near Townsville and you are more than welcome to come and kick a tyer or have a beer or bbq or all of the above dont forget to drop in at Gatton Western transport museum http://westerntransportmuseum.com/location.php near Toowoomba plenty there to run your tounge over anyway hope you enjoy the wide brown land seeya Paul http://www.dorotheamackellar.com.au/archive/mycountry.htm

me as well gotta love some gifts if you decide you dont want it and want to re-gift it just send it my way lol looks good gotta be pretty chuffed with that Paul

gudday fellas got reading this Brockway thread never seen one in Australia but they did bring them in at least for 1973 evadently the new owner was pretty happy with his ride and so were UK diesels so happy someone wrote a poem Bruthen is a town in south east Victoria when you start to climb up the great divide thought Brockway blokes might get a laugh seeya Paul

pretty much as Greg says maybe could reduce the bight on the drill ie maker the angle it cuts flatter so it bites less will help to reduce broken drill bits make sure the swarth coming off the drill bit is blue that way you no it is taking all the heat not the drill bit if the swarth is not blue you are going to slow and the drill bit will bite and break a lot easier good luck with it all Paul

things you need to check are phase angle which is the relation ship between drive shafts assuming there is more than one drive shaft between between front diff and gear box when you look down the drive shaft the uni cross's between the two shafts should not be in a straight line the rear shaft should be one splined notch behind the front shaft in the oppiset direction of travel for the pto shaft other wise you will get torrsional vibration between the two shafts the other thing to check is the vertical angle of all the uni crosses must be exactly the same other wise the unis accelerate deaccelerate at different speeds which will cause the same problem as described both of these problems will not be picked up by balancing the drive shafts as the shafts are not out of balance but will cause the annoying vibration you mention and are both caused by lack of properly trained mechanics they just no that computer says do this and thats what they do so it must be right that is the modern world though here is a link thingo for the second problem that describes it much better than me http://www.hotrodhotline.com/md/html/drive_shaft_harmonics.php will have to dig out picture of the first problem I spoke about had quick look on google only found the second and most common problem hope this is of some help Paul

Paper Back Hero chick flick type of thing with R600 as one of the stars all the way thru Paul

Gudday all the pressure regulator Im talking about is on the top of the box some 12 speeds have 1 regulator some have 2 depends on I dont know someone much smarter than me can proberly tell you this one is set at 65 psi and the regulator is before the gear stick selector if it is set to high you will hear air leaking out all the time even with good seals good luck and keep us informed seeya Paul

check the air pressure regulator on the box I think it is meant to be around 45 -55 psi Paul

gotta luv this its enough to put a horn on a jelly fish Paul

to my understanding I am probebly wrong only Mack Maxidynes had gold dogs in Australia and only for the first few years of the Maxidyne run just show something different. My 81 R model has all Mack running gear with a Maxidyne motor but no gold dogs as most dont here at all except for the later model CH onwards I think Paul

And if you blokes over there are after more good truck songs try this

thats easy " I'm married to my Bull Dog Mack " by Slim Dusty

now we all have read how much you blokes liked the Australian value liner now you can bye your own Aussie Mack brand new I'll even let you park it at my place wile you get shipping organised back to the states or some other spot in the world Paul

25 years here in Australia that went quick or Im just getting old

lads I only use one and have air start to start with works a treat can even start with no battery just need a pen to push the air soliniod Paul

well the 12 speed is the best tranny I have ever driven had trouble splitting into low once crap built up inside the gears on the low range side takes a bit to pull it all apart but cleaned it all out ran as good as new if it is only in one gear I have no answer if it is on all gears maybe the air ram on the box lid or the regulator is out of adjustment and not enough pressure ?? Paul ps I never use the clutch for splitting gears didnt no I was meant to

well I have been waiting for all sorts of advice but not much has happened so heres what I do roadranger I just change down through high range using engine brake if any fitted and leave it in high range until stopped just push the clutch in near the end the Mack 12 speed I just leave it in high split or low split and change down with engine brake working dynatard not that it does much if it is a heavy load ie over 60 ton I would split each down to 3 rd and then change down full gears was told once it is cheaper to wear out brakes than rebuild gearboxs but it all depends how fast your trying to slow down if some clown has cut in front well there mighten be much time for this fancey down shifting I guess what Im trying to say is each time you stop it is completley different Paul
