  1. OK, what engine we talking here. The later E7/EA7 have unit injectors on the side of the block that are fed from a single high pressure pump. Earlier engines use an inline injector pump fed from a piston type lift pump. And any airin a diesel fuel system is bad and will cause problems no matter what the make. Cummins were more susceptible to it with the PT (pressure timed) fuel system than others simply by design. Tiny amounts of air would make them run like a hairy goat. Fuel return to the tank simply is what's not required for the engine to produce required power at that time. More returns at idle while less is returned under full load climbing hills for example. Series 60 use a gear type pump to pressure feed fuel galleries in the head, where unit injectors are fitted. Most of the modern electronic engines (except E7/EA7) are the same. One thing these "bolt on" parts must not do is restrict fuel flow. The gear type pumps will differ from make to make, but they all need an unrestricted supply from the tank.
  2. Thanks for that thaddeus. Is the knorr ABS diagram. Very handy as we have volvos in our fleet too. I am trying to "break" into the Renault site currently to try to get a schematic for the quantum, because, guess what, Good Friday, and the phone rings. More air leaks on the nightmare. Much appreciate that diagram.
  3. Ah yes, the infamous "Greenmount". With a "normal" air system it is usually pretty easy to pick up a bypassing booster as air leaks out the exhaust port on a relay valve or quick release valve on the service brake circuit. But now in SA at least, rated trailers have to have pilot relay valves, and QR valves everywhere. Makes it interesting when you have a double hooked up and the trailers are dumping air out the exhaust ports on BOTH pilot relay valves. That one took some working out. But these quantums are in a league of their own when it comes to plumbing, and what makes it really hard is that the air lines are all black, basically the same sizes (6, 8 or 12mm) and bundled together tightly in the chassis, so if you are trying to follow a line from a valve, you have to cut cable ties, undo brackets, etc. to find where it goes to (usually another queer looking valve). And no, Mack don't have a schematic of the air system. As the foreman at Mack in Adelaide said to our driver last friday " I don't want to see you or this truck again!". Pretty poor attitude, but I can understand why. So I am off to Adelaide tuesday to have words with the SA manager and the workshop manager to basically tell them that while it has their brand on it, it's their problem too!!
  4. And we got a fax from our fuel supplier this morning saying fuel is now $1.50 a litre. Converted to US cost that is about $5.22US a gallon. Nothing like the Easter break to bump up fuel prices. Now anyone would think me a cynic for saying that. And on March 9 I posted saying fuel was AU$1.40 a litre or about US$4.88 a gallon. Not a bad jump for 10 days.
  5. Yes Thaddeus they are certainly different. I have now got my hands on a list of valves on this Quantum. 3 pages worth. What a nightmare. ABS system is basically same as most others, except the ABS computer is 12 volt, and the modulating valves are 24 volt! Then we have the collection of sensing valves for anything you can think of, pilot relay valves to activate relay valves to activate a pair of brake units on one axle. Load equalizing valve for the suspension, the aforementioned load sensing valve and numerous quick release valves. Personally I think a few less pilot valves and a bit more 1/2" and 3/8" air line would do exactly the same job. Most of the air line in the chassis is 6mm and 8mm. Oh yes, almost forgot, the air fittings are all single use, push in type with swivel. Most useless when trying to change valves.
  6. Still looks like a frightliner. New grille and......... not much else really.
  7. Well that kinda sums it up, the wife just had a look at the pics on the international site, and I quote " It's gorgeous". Says it all really.
  8. Looks like they let the work experience kids loose on the design computer that day! Definitely different. PT cruiser with a fifth wheel and bogie drive!!!
  9. Will take my tape measure on Tuesday Barry, have to go our Mack dealer so might scoot round the front and have a measure of the grille size and let you know.
  10. Oh please, it's bad enough I have to work on a quantum (big sister to this bucket) every second day, and then I come home to see this. Please people, have mercy. And they might have left the Class 8 trucks alone over there, but here we got the rubbish. The Quantum and Magnum with the EA7-470 and Cummins signature respectively, Eaton box and Meritor diffs all stuffed inconveniently into a european chassis with euro plumbing and electrics. Charming!!!
  11. Yes, Thaddeus, had a close look at that. I gather then that the air cleaners are still under the side of the cab then, that's where they are on our titans. Even so, I agree you should still be able to mount stack air intakes relatively easily. Only thing is the cost being prohibitive for the genuine article. But I guess some people will have that sort of money, and I hope to see some US models with them fitted.
  12. G'day Grant and welcome. Great to see another Aussie on board!
  13. Now I'm gonna go out on a limb here and guess it wasn't designed originally to load and unload quite like that??!?!?!?
  14. Yep, saw it every week when I was doing Adelaide - Darwin for 3 years. Very neat unit. He won truck of show quite a few years ago now in Darwin, then had it broken into on the same day and most of his gear stolen. Some nice low lives about. And yeah, why no MP10. Got the same story from Mack in Adelaide. Personnally I am thinking it has to do with our emissions laws as we are following the euro standards.
  15. Looks like you guys got your own US grille. Looks like an Aussie Titan bonnet, but no stack air cleaners. Why?, one has to ask. Still can't warm to the round front guards. Defeats the purpose of getting the engine bay heat out like our earlier Titans.
  16. Our Quantum has just returned after 3 days of much hair pulling and swearing by Mack dealer in Adelaide, me and my bosses. It went out Tuesday morning working fine after a head retorque and valve adjustment. Got to Adelaide some 200 odd km down the road and had developed a severe air leak. Driver and yard boss in adelaide determined it was from a large "ugly" valve in the chassis, left side, behind fuel tank. They ring me, yes I have seen it, and no, I have no idea what it is. They take truck to Mack dealer to be told, yes that is a load sensing valve for the rear brake circuit. (Air bag suspension). I get the phone call again asking if I had a valve or a kit in the workshop. No, never had one. Mack dealer tells them it is quite common for them to leak, do them all the time, but, we have no parts on shelf! Yeah, OK. Mack pull it apart, clean it out and determine that internally, it's stuffed, but put it back together "to get us going". Truck goes down the road 5 minutes and completely dumps contents of air system. I get phone call. "Ok, and where is the air leak" I ask. "Everywhere" was the reply. Nothing like being precise huh. Seems every relay valve (6 in total just on the rear end) and a few other assorted valves around the back end were leaking air. I ring Mack trucks trying to translate nontechnical irate driver speak into something coherent. Mack send breakdown van out. 2 hours later I get a call again, from Mack this time, and I quote " We have no bloody idea what's wrong". I said, " I do, it won't hold f#*%in air!!!!!!". We agree on this point. 2 days later (today) they figure out that a spring brake chamber is bypassing air internally, so therefore is upsetting the air system, in conjunction with this load sensing brake valve thing (still got no idea what THAT is) that isn't working properly, so the air is leaking out everywhere. Solution, change brake chamber, air leaks stop. WARNING!!!! Stay away from ANY truck that has any european plumbing in it. This is just another example of what happens when Europeans get their horrible little fingers on a normal truck. Die Volvo DIE! PS Anyone know where I can get a truck burnt on the cheap??
  17. Thanks bloke. Interesting you should say that. Even after all the work put into this little White, I still find oddities like what you have mentioned. Like I had always thought that 4000's had Cummins power and 9000's had Detroits. But as usual, there are always exceptions to the rule. Would have been a noisy ride with an 8V71. LOL But I can honestly say I have never seen one with a yellow peril up front!
  18. Still a watered down version of a REAL Titan. And can anyone please tell me why Mack trucks USA in their infinite wisdom don't use the full height "stack" air intakes like we have in Australia. I know you have conditions in Arizona, Nevada and New Mexico similar to here. And before anyone gets cranky with me, the 2008 Australian Titan is a watered down version of a real Titan too!
  19. Thanks very much for that. She was worth it.
  20. Now I'm not saying you guys in the US are getting it easier, far from it, freight rates are relative. Here in country South Australia, not quite the outback, we are paying $1.40 a litre, when converted to US gallons is $5.299AU a gallon, and factor in the exchange rate at around .92c US to our dollar is about $4.88US a gallon. Not that much difference. And who said the oil companies aren't fixing prices globally??????
  21. Bit of a let down for you guys, but still a classy truck to be heading your way. Bit of irony is that the last model superliner basically shared the bonnet design with the Titan, and now the Titan has gone all round and aero on us! (still looks wimpy). Will be interesting to see if the "turd herders" (stock crates/ livestock carriers) are able to spec their Titans with round tanks still. Can't imagine those boys wanting square tanks that reduce ground clearance/ escape clearance for the dirt tracks they run up and down on the big cattle properties, as well as the suicidal wildlife that inevitably wants to take a close look at the underneath of trucks. A big 6 foot plus 'roo at around 300 plus pounds will take out fuel cross over lines and brackets as he passes underneath when round tanks are fitted. Those square ones are just creating problems there.
  22. Yep, pretty much the dust and heat factor forced the air intakes upwards. The ram effect of putting the intakes up into cooler undisturbed air is also a plus. But another interesting innovation to come along in the past 10 years or so, is the use of pre-cleaners half way down the intake pipe. These help eliminate the solids out of the incoming air, thereby extending the service life of the air filters.
