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 

Paul

It's a good read, theres a secobd book from the same author

 A 285 is strictly Air to Air cooled charge air! I beleive !

I would agree with this

Paul

If you keep on just poking along like you are you might be surprised at just what can be achieved with out spending bugger all

Nice and steady, you may get away with no sleeves or pistons or maybe you will need just one or two 

Paul

We nerd KS to provide some info on this, dunno how big that back is at but huge is a fare guess

Looks like a Alsakan Freight lines truck, or that style of truck

Are these dry sleeve or wet sleeve motors? And if they do pop out why could't you just reseal it and pop them back in?  You can check the condition of the cylinders and check for cavitation if they're out. 

Also do Mack's have problems with dropping or sinking liners like Cats do? I'd imagine sleeve shims would not be easy to find for one of these. 

If someone is putting a lot of force on a crank to move a seized engine then pushing as sleeve out is well with in a possibility 

Then as Joey suggested these are a press fit or freeze and get back 

This is all gunna be a challenge with a pistion still stuck in a sleeve 

Anyway thats how I would deal with it 

Paul

Very good, please feel free to share any photos or memories

Looks like the box was run with bolts loose and then the inners broke off in the housing or pulled out

I reckon your right, this isnt as easy to notice if you dont know we're to look

The bolts towards the center of the camel back I doubt anyone can easily see from walking around doing a pre trip inspection 

So depending on how the conversation went with mechanic I can sort of understand how this could all unfold quite easily 

Gotta remember the mechanic can only goes on what is described to him and the driver can only describe as best as they can 

I dunno we need to try to not be to critical after the event

Bloody lucky everthing survived the ass puckering adventure at 65 MPH I reckon, I know I would of had white knuckles pulling the truck up 

Anyway I'm sure all involved are well on the way to getting things sorted now

C4Ed I'm judge you the truck or anything else just chucking some thoughts about

A lot of the people on here are really experienced in all facets of Macks so dont judge them to hard as they can only call it like they see it

Paul

Well this is good news, now that's gumna sound strange

But let me explain, you stopped forcing it before you went to far and broke something 

Mouse piss etc should be of concern, or at least it would be to me, must be some valves open either fully or partly 

How did these mice find their way into your motor ?
