Aerodynamics????? Back when fuel was 50c a gallon who cared. LOL.

This one is a 1999 model. Renault everything except the driveline. The air dryer let go during the week and, true to form, only available ex Mack for AU$925 plus tax. So I got a generic Wabco unit that looks almost identical to the original Knorr-Bremse unit and had to fit a D2 governor valve to the compressor as the Wabco dryer has it's signal port different. Job all done for under AU$600. And now when it dies again, (and it will) cheap generic parts to fix it. The CH chassis would make life a whole lot easier. An ISX, what a dream......

If you can point me at an online wiring diagram I might be able to sus out a potential problem.

I love these tricky ones. NOT. Problem is never where you think it will be. Is the truck fitted with a circuit protection box for the trailer wiring. They can be a source of many problems. Is the marker light fuse shared with any other circuit, as this can create problems on a completely different circuit. If it was just the cab roof lights I would say check your cab earth first, but trailer not working as well tends to point at the one power circuit. You have a seperate switch for marker lights, or do they come on with headlight switch in "Park" position. If they come on with headlight switch, I have found sometimes the contacts in the headlight switch can be a problem. I guess best thing is to break out the test light and see if you have power to the switches and relays. Also ensure you have a good earth for the relays and that they are working. Wouldn't be the first time a "new" switch or relay didn't work.

Yeah, as I said in one of my earlier posts, Mack book time is 5 hours to REMOVE the sump.

Nah, only the gear shift is different, accelerator, brake and clutch pedals are all still operated with the same feet. I did some work a while back for Hunt Energy (yep owned by Nelson Bunker Hunt) when they first started up over here, and they imported all their stuff from the oil field salvage yards in Odessa, Texas, so all the trucks were L/H drive, but pedals still the same. You're right though, takes some getting used to shifting with your opposite arm.

I have to admit, when it was younger the ride was quite good, 4 airbag cab suspension with a shock absorber for each bag. Unfortunately the big let down is the front cab mount set up. A cantilever/scissor link type of arrangement with too many bushes to flog out, so ride quality starts to deteriorate badly, and the cab actually shifted to the left at one stage! ( because of our road camber with R/H drive). Would be ok on nice smooth European roads, but unfortunately like so many other euro imports, they underestimate or completely ignore our road conditions here. And to replace the mount link bushes is one major job. Cab has to be suspended in the down position from an overhead gantry. As for SISU's, yes there are a couple in Australia I have seen used in mining/exploration work, 6 wheel drive variants from memory. Tough as you can get. I think one had a mini drill rig set up on it for core sampling, so was heavy and still running off road all its life. Think they might have been pre renault though as the cabs were like square boxes.

Apparently they weren't thinking. Not clearly anyway.

I have posted a few times on here about our woes with our "Quantum". Luckily they never made it to the US ( probably tipped overboard on the way across the Atlantic). For those that are curious here are some pics. I know ThaddeusW wanted to see the engine bay. As you can see not a very user friendly hybrid, especially the position of the compressor and clearance between front crossmember and sump. And the 3rd last pic is enough to make any red blooded Mack man cry.

There have been some comments of late about the Australian "Stack" type air intakes. Some like them, some don't. Personal preference I guess. I have taken some pics with my phone (yeah forgot the camera ok) of one way these are fitted and used on an '07 Superdog belonging to one of my customers. Might help anyone who is thinking of trying to fit some to a US model. I will post some pics of his other Superdog stack setup a bit later. Please don't laugh at the colours ( we call 'em bacon and egg sandwiches ) but is a requirement as a contractor to Kalari.

Got some pics of a 2007 Superliner grille hear Barry, not sure how much difference there is with the '08 models. This was a new Superdog in November. Spoke with the owner today as I do his servicing and he seems to agree with me that the Superdog and Titan share the same bonnet, or are very close. And as usual after a long weekend, was chaos today so when I finally escaped, I forgot the piece of paper I wrote the measurements on. And surprisingly, there were no '08 Superdogs or Titans at the dealer today either. All on order I was told.

I know in Australia that unless you specced another colour, red was standard chassis paint colour back in the 70's and 80's. I love the user name and avatar by the way. Very Australian icon.

I just noticed today on my way home that diesel is now AU$1.55 per litre here. 5 days ago it was AU$1.50. That works out at about US$5.39 a gallon. When is it gonna stop???!!

Was the engine running recently, if not double check that the dizzy is in correctly, not 180 cam degrees out. This will cause misfiring and carry on when trying to start, but will show up on a timing light as correct timing

Pretty much they are a Cummins rip off. Ok, the filters and bolt on bits are different, but block and head are pretty much identical. If you see a D16 next to a Signature with its shrouds and tin work off, there isn't much difference. And they have kept the design and scaled it down for the D12/D13. That's how come all of a sudden Volvo's had engine brakes. Have to agree with old mate about them being gutless too, our 550 Volvo just isn't a shadow on our 550 Cat powered Sterling. They might be same cubic capacity, but they just can't make the torque.

Yep can do that for you Thaddeus. Won't be til tuesday though. I finally got an air leak on this thing that was easy. Leaky QR valve on the rear drive. 10 minute job. Something has to go my way sometimes. Pretty average looking engine bay til you look at it from underneath. LOL. Just an EA7-470 stuffed into a european (Renault) chassis. Will post pics tues night (local time) hopefully. Some pics of this things air system rear of the gearbox.

This is a link that shows the old Detroit 2 stroke diesel fuel system The injector fuel is supplied to the injector via pipes external of the injector, but supplied from, and returning to galleries in the head, in this case 2 galleries, one for supply, one for return. Take out the external pipes and you have basically todays modern unit injector setup. http://www.tpub.com/content/construction/1...s/14264_183.htm

Agreed yes, there is entrained air in all fuel supplies. But this is negligible and diesel fuel systems are designed with this in mind, as most have a minimum of 1/2" supply lines, but of late more like 5/8" or bigger to reduce vacuum restriction in the fuel line. As for the returned fuel, current engine technology isn't true "common rail" yet, although the new Series 60 Detroit is supposed to be, but I can't comment as haven't looked into it yet. What is normal situation with unit injector type setups is a fuel gallery in the cylinder head which feeds to the injectors. The injectors sit in a machined "hole" in the head ( usually in an injector tube or sleeve) and fuel under pressure is fed directly to them via the fuel gallery. The "out " end of the fuel gallery is usually smaller or fitted with a restrictor of some type to allow pressurization of fuel in the gallery, thus supplying pressurized fuel to the injectors. This fuel comes directly from the ift pump, usually a gear type either directly, or through a filter. Sometimes the filter is positioned on the inlet side of the lift pump, and sometimes there are 2 filters, one before and one after the lift pump. So to answer your question, returned fuel to the tank is what is not used by the injectors. Earlier Injector pump and individual injector type fuel systems are basically the same except the fuel gallery is in the actual injector pump, which has its own spill return line and some systems have spill return off the injectors as well. I will try to get into one of the engine manufacturers sites and send you a link that will give a diagram, easier tpo understand when you have a picture I find. I hope this clears it up a bit
