Dont think long hood Road Boss was ever sold in Australia, well at least not that long 

Paul 

Hmmmm

Dunno about the looks but looks don't make money

Do they still make these (assemble) these in Australia?

Paul 

Sounds like the air regulator isnt working, wel. If it was a Mack transmission I would suggest that 

Dunno about the RoadRanger but think their gunna be similar, sounds like someone has hooked onto  the wrong air supply and your getting full air pressure to the switch

Rather than correcting their mistake they have tried just changing the regulator 

Paul

Well a few thoughts here from a bloke that knows SFA

I dont think the injector would be blocked, the diesel system is postive displacement, what goes into the injector line feeding the injector must come out 

So am wondering if that injector is really faulty and just dribbling away or stuck and letting the fuel return straight to the tank

Compression test wouldn't hurt and only takes time to perform and the correct compression tool

I am a loud mouth that said its nothing more than a fuel leak so perhaps don't listen to a word I say 🤔

I guess report back when you have some more findings

I would expect to find around 450 psi when checking the compression and all within 50 psi of each other 

Maybe pull the suspected dud injector and clamp it on the fuel line upside down and see what the spray or dibble is like, just keep your face and fingers etc away from the firing line, or for that matter all your body parts 

Paul

I think the problem is all this QA rubbish and companys trying to get 5 ticks on their logo, they farm everything out so the companies take no responsibility for the product, only for the fitting of the product 

Do big truck workshops in the US even have a injector pump shop to rebuild things or at least check them, I doubt they do

It all went pare shaped when places started having specialists in just on department instead of mechanics that could fix anything 

Local places to me had sales me and spare parts people that started on the workshop floor, all gone now and it shows

Paul

Why I was searching for other things I came across this photo from the last time I saw this truck

Emerald QLD in 2017 or 2018, thinking very early 2018

Still was looking pretty good then, have passed it a few times over the years, seams to get along pretty good and will get you there a lot quicker than my little 320 

Paul

Quite right Adkat

As they say a picture is worth a thousand words

Jack Ehret Loadmaster! Taken at our truckstop in Gilgandra. This time Jack decided he'd leave the dog behind! I think this trip was to the Gunpowder mine.

Sime dribble from me now, this I believe is Fruehauf "Super Hefty"

A Super Hefty had chassis rails 450 mm or 18 inch deep, 100 mm x 25 mm or 4 inch x 1 inch top and bottom flange

Probably tared around 10 ton, I have a double rail McGrath trailer that is built along the same lines or principles, it tares at around 9.5 ton but isn't as strong as a Super Hefty Fruehauf, I can take the camber out once in a while with big weights on

On my Fruehauf Cattle Cruiser I have noticed a extreme amount of camber in the axles 

Super Hefty's had this as well 

Fruehauf rated the Super Hefty for 50 ton carrying capacity from the factory and plenty of blokes went past that suggested limit

Was some tough old blokes back then and even tougher trucks

Paul

Thats a good result, another happy Mack person

Paul

I bet this sounds great 

Paul

Hmmmmm, dunno what Roadranger parts are worth but Mack parts are plenty dear enough, even PAI are just as bad

To me just changing the crook parts is always cheaper but to what its worth I have no idea 

Paul

Am thinking it is time for me to upgrade to these cold cut style saws

No more changing blades all the time and most importantly no more sparks setting distant things on fire 

This is pretty common and requires some fast work with what ever at hand to beat the fire out

Also have set myself on fire on the odd occasion lol

I have only bought Makita power tools for well over 30 years, are they the best ?

Dunno, they are a good brand than gives little to no trouble but they do cost a packet

Paul

Sounds like it is glazed up, handful of naphthalene in the intake is reported to solve this problem 

I have never tried this but have heard plenty of blokes mention such things

Paul

Its a lotta coin, but it looks in pretty good nic

Would you rather drive that or a modern jigger with add blue def and all the rest of that girly stuff

I know which I would prefer

Paul

Sounds fine but I would think any oil from the compressor should be getting sucked into the compressor and it would be before the turbo no after it

Just wondering what can cause oil to collect in the inlet manifold, if it was a petrol car it would be coming from the rocker cover EGR valve but I have never seen anything like this on one of these motors

Makes me wonder if something else is going on for the oil to be there

Was any oil in the charge cooler pipes ?

Perhaps the oil is from elsewhere,  but where 

Paul

Were did the oil come from on, if it's the inlet side shouldnt it be only air

Or is there something else feeding into the inlet were oil can come from ?

Paul 

Dunno the science about ether addiction, I  will say it is with out a doubt in my mind a genuine thing

I dunno if it damages stuff insude the motor but at the very least something changes, I  thought maybe washes carbon out of the ring and piston gap but if Jo says its causes more damage than that I would believe him

To me it is much easier to just fix the problem than it is to muck about spraying crap in there 

This is also not directed at you Truckie but at the question on ether 

Paul

As these other blokes have said, you'll have to bung up some pictures before anyone could even hazard a guess on value 

Paul

Well that rules out the rack been stuck

Maybe move things about a bit while the tank is pressurized and see if you can find a leak, shake twist fiddle etc 

Maybe try cracking the return to tank part of the fuel system at the injector pump, check the flow there 

Is something is floating about in the tank ? I don't think this will be likely from what you have described 

This has happened when it is running so I  believe that it must be in the supply side of the fuel system 

Paul

Of all the Macks I see on offer in the US, the Pinnicale is by far the most truck like looking truck that Mack offer in the US 

Australia has a totally different line up with totally different look on all except the Anthem and even that has been dolled for Australia with the removal of those stupid looking antler mirrors on the front 

Paul

There's been a few major milestones achieved in recent weeks

A huge pat on the back is deserved 

Well done, sounds great

Paul
