No idea Hans

Might of been and Australian thing, I really couldn't say

The Australian content was pretty high during the R and FR models

Paul

Well I thought to myself, I reckon I have one of those on a tank laying about

And well I thought right

Has 1985 on the tank plate, was off a R model Mack 

No more details 

So I'm guessing it was near the end of R model run

Is be curious to see what the actual gallon size my tank is?  It is an alum tank from an R model.  One of the larger ones I've seen, length wise.  It's hanging under the bunk in my signature picture.

I've see ones that are near 1/2 as long as mine.

Apparently there was a 1 start, 2 start and a 3 start tank

The single start tanks are really short 

Maybe only 6 to 8 inches of flat if measured length ways

2 start tanks are about 12 inches of flat

3 start are longer at a guess 18 - 24 inches

I reckon on some old B models I have seen even longer again

Paul 

Yeah, he's good to listen to, a lot of this stuffs been going on for quite some time now 

I have listened to Paul Harvey for some years now, the first time I ever stumbled across him I thought to my self, wow, this jokers saying a lotta what I reckon we are all thinking 

Paul 

Never known of a clutch switch on a Ferguson 

Sure the loom isnt get caught in a linkage or something and getting pulled a bit when the pedal is full pressed 

They are normally pretty reliable 

Paul

Nah, there's a hose with a fitting to drain the tyres to recharge the tank, three tyres apparently gives you enough to get here going

Once your started you refill the tyres from the trucks compressor 

As I said a pain in the neck

Paul

Well you fill it up with air and try again

I really cant imagine a air start is much good in a cold part of the world, the air valves freeze in Australia at -5 C which according to google is 23 F and it gets a lot colder than that in parts of North America I believe

Apart from the novelty air start is a bit of a pain in the neck, battery technology has improved so much that air start has been made a non event even in tough going areas of Australia

5.73 with a OD 12 speed will give you about 55 MPH on the governor if you are on 11r 22's 

5.73 was a common road train gear even with a E9 at 500 HP, but you are shifting 200,000 pounds plus all day every day 

As to a 350 in 1980, I  was pretty sure that series intercooling came out some years after 1980 and that was when 350 HP  was first talked about for a E6 in Australia 

Increasing the revs on a E6 will dramatically reduce it's life span, they are a genuine million mile motor but, I believe and so do most people I speak to tend agree they are at their happiest at about 1950 rpm, yes you can run them out to 2100 plus but they really arent in their happy place 

I cant see or think of any reason you would have to use the tip turbine, the chassis mounted cooler should be fine, I  wonder if anything has to be done to control boost, the turbine controls boost on a tip turbine to a large degree

how you pair it would greatly depend on how your going to use it. a show / play truck not as important. a daily used work truck needs to be much more specific. work truck the trans need to be compatible. can't have a wide range main coupled to a totally different aux.

Pretty much what he said, it really depends on what your plans are for said hot rod 

There's a huge difference between working something out on paper and going "it'll work" and the truck having any degree of drivability about

Paul 

A Foden in Yanky land, surely a sin 🤔 lol

Struggle to even Fodens in Australia, NewZealand still has a few though 

Paul 

Totally open to correction on this

I believe this motor is still a Thermodyne

Econodyne was a 4 valve chassis mount intercooled motor

It may also depend on the part of the world each of us is from as to what we call them

Can this engine be swapped  in place of an e7 and just remove the tip turbine set up and plumb the existing chassis mount charge air into its intake ?

I dunno why you would unless there is some drama with what you have

It wont give anymore power or anything like that

The old tip turbine is pretty proven and reliable

Unless I have missed part of the story here

Or are you looking at buying a motor like this from a truck and fitting it into a different truck ?

Paul 

And I dont think two valve or four valve made much difference if any to the torque quoted by Mack

4 valves were more efficient and gave better fuel economy

Heres stuff from a 1980 brochure: 

 

I think the tip turbine and the charge air cooler motors were produced at the same time then. Doesn't show a tip turbine 350 but I think you could get a rough idea. 

This part of your picture show a coolpowered 350

Series intercooled tip turbine motor

Thats a good page of information you sharex there Bob, thank you

Also, the original Maxidyne trucks from say 1966-1972 have two as well. However, the lower one is open ended under the hood. I assume so the intake air stream is partially warm. These trucks didn't have charge air coolers so I don't know why they did that but they did......

The original Maxidyne's only had the 1 intake tube in Australia 

It wasnt until the coolpower motor came along that two intake tubes were needed, however in Australia the second intakecame from a second aircleaner for the turbine and the other aircleaner was for the motor intake

Welcome to the forum RoadRanger 

A interesting life behind the wheel

Paul 

Is that a train or a tram, think you blokes call them trolley cars

Mack looks tiny in front of it

Paul

Mrs Mack is very slowly in between this atrocious weather getting sorted, she never had that much wrong but I started fixing one thing and noticed something else not right and so on

A bit like the little old lady that swallowed a fly, well I hope I dont have to swallow that horse lol

To make things right is lot harder than to just get them going sometimes

Paul

Even in Australia the same deal with logging on

Joey I can tell you I am sure glad I live in Australia with our health care and not the US with yours

Paul

From what I know and everyone knows thats two tenths of SFA the rails need to be fully seperated to clean the rust out fully to allow them to close up

Apparently they allmost always spring back into shape when this is done

So sadly I think you need to go all the way to get the result your chasing

I have never done this and am only passing on what else I have seen or been told

Get your self a 3/4 cordless rattle gun and get into it I guess

Paul

Hmmmmmm

Hope it all works out for you Joey

Second book is called "Fifty Shadeds of Tarmac" 

https://www.goodreads.com/book/show/27427571-fifty-shades-of-tarmac

Now me been me and been very different, I contacted the Andy MacLean direct and paid him so he got all the money and not the likes of Amazon etc 

Book turned up with a signed note inside

That is the book KS shared, "Me and my Mack"

You jokers should tell the chief cook and bottle washer and you might one for your chrissy stocking

Paul 

Well my 20 cents worth which is hardly worth 2 cents tells me if it was mine I would fill the bores with diesel and a little bit of petrol (gas for yanks) drop a rag in it and set the bores on fire until they burn out

This heats the bore and hopefully allows some possom piss or diesel or what ever to get down past the piston to the rings

I would do this a few times  until I can see some results

Then maybe try budging it a bit

Drop the sump and  see if you can shift any loose pistons up

Probably only the ones TDC, may need a jack on the floor with a block of wood on the rod

Dunno the more you can get moving before going crazy means the less strain on everything 

Anyhow thats what I would be doing

Nice and gentle is the way to save money

No swinging big sledge hammers belting the crap out of things

One slip and you can really make some giant steps in the wrong direction
