International Travelall

I will look into parts from the USA. This vehicle has had the suspension changed around a bit as it was formerly abble to go on the railway as well.I am going to assume that the engine is blue it looks a similar colour to the holden blue motors.the transfer and gearbox seem to be in good condition.The rear diff needs speedy sleeves on the inner seal as the dirt has got under them being 4WD and cut large grooves.The motor itself runs fine even with old fuel.It does need a few of the leaks fixing but that it is nothing.The body rust however is a lot more a worry.I have seen a few other aa models down here in tassie cut no travelalls sadly.

My understanding of this is that the Aussie Black Diamond 22. 240 and 264 went from 56 to 58 but that the first of these may still have been vertical valve. Have also seen a reference to an Aussie Black Diamond with a red tappet cover ??
Them the Aussie Blue Diamond from 58 to 62 ( also coded ABD ) during this time the 220 was dropped and the 282 introduced. Then Aussie Gold Diamond 62 to 65, then 6-282 , 6-281 and 6 - 283 ( all 282 cubic inch with the 6-283 limited to Army 6x6 truck)
US built engines are a whole different story .

Atkipete - Have you come across any IH literature, factory or engineering memos, or IH advertising, that specifically refers to the Tilt Valve ABD engines, as Blue Diamond engines?
My understanding is that IHC Australia only ever referred to these engines as Black Diamond engines, and the Blue Diamond name came about as a general reference name, just as Detroits became referred to as Jimmys.
It's interesting that Wagga Tractor also refers to these late ABD engines, as "Black Diamond, Tilt Valve engines".

Yes, the ABD engines of 1956 to late 1958 were vertical valve engines. IHC Australia then "upgraded" these engines to Tilt Valve ABD's, with a brand new, wider head, angled valves, and domed pistons .. but it appears that they were still referred to as Black Diamond engines, by IHC Australia.

It hasn't been helped by the fact that the Army reconditioned a very large number of ABD-264, ABD-282, AGD-282, 6-281, 6-282, and 6-283 engines .. and then painted them either grey, red or blue!

The paint colour was probably an Army thing, with different depots using different colours .. perhaps so the officers could track down which depot reconditoned which engine! Or maybe it was because the Workshop Sar-Major just like that particular colour!

The AGD (Australian Gold Diamond) engine actually appeared in May 1961, in the "new" AB and AACO-172/182 series. I have a double-page "new" AACO model advert, confirming this date.
The AGD engine featured valve rotators, an increased capacity water pump, an improved oil-bath air-cleaner, a pre-engaged starter motor, and a full flow oil filter.
The 6-281, 6-282, and 6-283 appeared in 1965, in the C-series.

These last three engines were just slightly improved AGD engines, with minor engineering upgrades, and a new name. I have seen both red and gold used as the factory paint scheme on these engines.

The major difference between the AGD engines and the 6-281/282/283 engines, was in the angle of the valve seats. AGD engines used 30 deg valve seat angles for both inlet and exhaust .. the 6-281/282/283 used 30 deg for exhaust valve seat angle, and 60 deg for inlet valve seat angle.
There were other minor engineering changes that I can't currently recall.

The Tilt Valve AGD-240 and AGD-264 used a single carburettor, and a single outlet exhaust manifold. The AGD-282 used a single carburettor and a dual, split exhaust manifold, the same as the later 6-282.

Every 6 cyl, Australian IH engine from mid 1961 .. from the first AGD engine, right through to the last 6- series engine .. used a Bendix-Stromberg BXUV-3 carburettor, with just minor variations in parts and some part numbers. The 6-283 just used two of these carbys, also with slight modifications.

I have the Bendix-Stromberg carburettor catalog that itemises every Australian Bendix-Stromberg carby (and all its part and gasket numbers), as fitted to every Australian-built vehicle (that used Strombergs) from 1962 to 1979 .. and this catalog includes all International trucks (including Army models) in this period.

On the following linked forum page, there's two excellent pics of an Army MK5, 6-283 (post #316 by Brad T of Sydney).
This is the twin carby engine, with the two-piece, dual-outlet, semi-extractor style exhaust manifolds. Note that it's painted blue!
I only ever saw these engines painted red originally, in all the MK5's I ever worked with, or around (which is probably about 100 or more - I used to load a convoy of around 35, MK5 tippers, every day!)

Ron, re Blue Diamond engines. What I was quoting from this morning was a typed list that I think I got from someone at IH. I dont know who the Author is but the info seems to agree with other stuff I come across. Will have a look though IH adds for the late 50s early 60s and see if I can find any reference to The Blue Diamond. Also will ask around at Sandown.

Bits of my black daimond 220 (with vertical valves) is a grey colour. But who knows if thats original. I have no idea what this engine came out of.

Just thought I would add my 2c worth going on the stuff I have read and found. The ABD was first an Australian BLACK diamond
And was used in the AS model. When the AA came out it was advertised as having a new Australian BLUE engine both engines having the same ABD prefix of the engine number. Obviously the blue diamond was painted blue and black was painted black with the later tilt valve black diamonds having a red tapper cover

Atkipete is spot on

I had an AA110 and it was about a 59 model with the aluminium grill it's motor was blue and it had a two barrel Holley downdraft 2110 carby similiar to the flathead Fords ran, Murphys wouldn't happen to be this one by any chance
