I would think if it had blow by your gunna start to start to make boost but I really dont know about 

Paul

A lot will depend on how much load and what revs your at

I would expect maximum boost at the cross over between maximum HP and maximum torque under full load with a big long hard pull

Paul

Same questions I always ask

When the boost stops increasing are you making smoke

If your making smoke you probably have a air leak or something not working right in the intake

If you are not making smoke a lack of fuel is the problem 

Paul

New to me

Paul 

Struth send me your shoe size and I'll send you a pair of Blundstones

Tiz what most working men wear in Australia 

Paul 

Time to skip all the guess work, you have a fuel leak, nothing more complex than that

So as I have said many times, get some old inner tube, a couple of big flat washers, a air fitting to match the compressor in your shop, a fitting to screw onto the air line fitting, and a hose clamp big enough to fit over the filler cap

Cut the inner tube big enough to cover the filler and go down the sides a bit

Put a hole in the middle of the inner tube, air-washer-inner tube-washer and another fitting to clamp all of these together

Then pop the inner tube over the filler neck, and some air pressure, not a lot, wind the regulator down as low as it goes on the shop compressor 

Then search for the wet spot, by the sounds of it, it's gunna be easy to find 

Hope thisis of some help

This isnt a lift pump or filter or anything else, this is a bad fuel leak

Paul

I reckon they are both pretty bullet proof 

Paul 

Did you coat the inside of the tank to stop any oil seeping thru, I find these tanks are always wet and dusty unless this done

I have never done it myself, tanks I have that are coated are always nice and clean and those that arent are always dirty

Paul 

First things first, when your trying to start it does it have smoke coming out the exhaust ?

If it has smoke and wont start you have fuel and prime isnt your problem 

If you dont have smoke you have a leak 

Cant give anymore help until we get the basics sorted first

I wish I woulda found that truck first ha! If that has a 300 motor, is it a ENDT or a E6. Don't ENDT's only go up to 285hp from factory? I would want to change the tranny on that truck and get rid of the front pizza cutter steers, those tires will sink on most of my jobsites! 

All of these motots you mention are E6 motors 

285 is a coolpowered  Maxidyne 2 valve

300 is a Maxidyne none coolpowered with the intercooler In front of the radiator and was a 4 valve

350 is a Thermodyne none coolpowered with the intercooler in front of the radiator and was a 4 valve

300 can also be a Thermodyne coolpowered motor that is a 2 valve or maybe a 4 valve depending on the era

Can also have a 350 coolpower that is series cooled with 2 valveheads 

There is quite a long list of options, I have only scratched the surface here

The coolpowered motor was a game changer in the industry for many years and really set Mack up as the leaders for a long time 

It is important to understand the differences when shopping for a truck as the sales man will always quote the higher value on power when selling a secong hand truck

Even if you have a really good understanding I doubt anyone can tell what the pump is set to by looking 

Paul

Dunno about on your side of the world but over here the chassis number is used for identification 

In Australia it is punched into the RHS rail behind the first drive axle 

Probably of no help but its a start

Not only should it not go past 90 degrees, they should be setup to be at 90 degrees with brakes applied. Maximum brake power at 90 degrees. Your brakes are not setup correctly.  

That isnt correct, they should not be set like this as once any wear is apparent they will be past 90 degrees

Wow! Thanks, Larry.

If you ever see the truck again (and if you will happen keeping this point in your mind) please pay a bit of attention to the sleeper. The one I have on my R (and the one I built) seemed a kind of unique since I never saw a similar bunk on any truck or a picture. The one on the B is not a 100% copy too but very (95%-?) similar. I have no practical need in any info about it having my bunk almost finished. But would be cool to learn its origin and design details. I will try finding the truck owner's contact info either. Thanks.

It must be time for a update post on this bunk of yours Vlad, gotta be some happenings since we last viewed it 😉

Paul 

Well my 20 cents worth of useless advice

Dont be to hard on old ,ate flogged the truck to you, any truck over about 10 years of age wont be original and will be changed quite a lot to suit what you want 

So keeping this in mind I would start collecting bits and pieces to make it into what I want it to be 

Keep using it until it goes KAPUT then start chucking your stuff into make it what you want 

Also some advice from a fellow truck driver at Springsure in QLD Australia one day, was about to head off in my 320 hp Mack pulling a road train, up around a 100 ton (220,000 pound) heading south to Roma and have to climb Carnarvon Gorge, now this is really really steep and has bought plenty of trucks undone, it has "caution trucks must use low gear" signs for climbing the hill, only place I have ever seen this for climbing a hill

Anyway this truck driver says to "dont worry lad, plenty of blokes have climbed that with a lot less power pulling more weight than you have" 

Moral to the story is you have plenty of power for anything you will ever want and unless your running coast to coast that extra power isnt gunna make much difference to your day, slow and steady and enjoy the view 

Paul

 Top photo was a late model KW that electronics had gone KAPUT on Carnarvon Gorge and couldn't lift off (wheel spininning on dry hard bitumen) 

Bottom photo is after I over took him stopped there, had to split up his road train and pull a trailer up at a time 

Guessing he was a 600 hp monster, horse power only gets you so far

Same here bud that’s messed up I usually don’t even follow them anymore since nobody responds it wasn’t always like that here…. You look at how many people checked it out and nobody said anything it’s ridiculous why did you even go there dumb ass… and thanks for nothing bob

Yeah it has changed on here in recent times but that is the one constant 

Paul

Well I hope you had a CRACKER OF A DAY, dunno much about the navy, even less about the US navy 

I wouldnt be much chop in the navy, vomit and more vomit lol

Paul 

I used to crop photos once but I noticed that while looking at photos from many many years ago that the most interesting part wasnt the subject of the photo originally but rather something in the background 

I also got into the habit of just getting every photo printed as I  worry that years to come some photos will get lost because they are stored on technology that is out of date 

A bit like if I was to have stuff stored on a computer floppy disk from say the 90's I would have no idea about getting access to it today

Remember those big laser discs before DVD's that were around 12 inches diameter, could we even watch one today

Or DVD's in 10 years time ?

Paul

They are some good looking bulldogs there, I  would have absolutely no use at all for a R 800 but I would love one

I have seen two come up for sale but are gone in a heart beat, they only made 26 so the chances are slim of me ever getting one 

Paul 

Looks like a great event, also looks like Im gunna have to take up golf by those golf karts ☺️

International Scouts always looked good to me but were big sellers in Australia, dont think were big sellers in the State's either 

There's a way I was taught to reduce the size of imgages all at once and 100s upon 100s can be done in one go

Have a look if your interested, I  still had to get a hand the first go or to but once I new how it really is as simple as 

Paul 

No matter what the motor you need to keep a eye on the pyrometer when climbing a hill

237 has balls bigger than you can jump over

But honestly if it needs this much changing to suit you are probably better buying another truck

Paul 

From New Zealand 

From I believe Patrick Mark Mahoney photo

 Maroa Logging NZ Forest Products Kinleith Tokoroa (1978-1980) Kenworth 848 Off Highway  very similar at the time of the Canadian Pacific trucks at Kinleith and Kaingaroa

Can see a R 800 behind the Kenworth 

Interesting to me at least, these were stamped DM on the chassis rail, I  am thinking they used a DM rails to build the R 800

Australian and New Zealand Macks are very much custom built and almost all used a R model chassis except the R 800

This applied COE and conventional cabs well into the 2000's
