Can anyone shed any light of the 1930s A179 petrol that AEC developed for the War Department? I understand that it was a design based on a current production Diesel 6 cylinder unit, but which one? I've got to try and locate a rebuild-able core for the A10 Tank that is under restoration in Lincolnshire. The production machine has the A179, but as the vehicle we are restoring is the original 1930s prototype it may have had the original diesel. I am under no illusions, finding an A179 to rebuild will probably be impossible....would a 1930s AEC 9.6L Petrol be more easily located?

Thanks,
Alastair

I think the engine might be the A180 8.8 litre Diesel, but I shall have a look through my reference library when I get home.

I now have the manual from AEC. This is a side section.
It is termed A179 9.6 Litre.
As you can see it's dry sump, did AEC make many dry sump units?

They certainly made some, I have only seen them in flat engines but my knowledge is limited.

The AEC 9.6 litre diesel indirect engine was a development of the 8.8 litre unit and fitted in the Valentine tank, armoured car, armoured 6x6 mobile command vehicle and many stationary applications like the compressors and pumps used in the Mulberry Harbours. The final development in a continuing quest for more power in the tank was a petrol version of the 150 bhp 9.6 litre diesel, but it was still not deemed to be adequate. Further engine development for the tank relied on American units.
All the tank engine units had dry sump lubrication and an air compressor for the track steering controls.
Rex Cadman restored an ex target range Valentine tank 20 ? years ago using an AEC 9.6 Valentine generating set I supplied, a very quiet and smooth running engine, and it was delivered by my AEC Mercury!
In an earlier post I mentioned that some Dutch military vehicle enthusiasts had found several Valentine engined AEC Armoured Cars in a scrap yard in Namibia while the were working in South Africa, if you are interested I will find their contact details.

Regards, Martyn
