[MRA]

[Bungle]

your not the first person to ask this and there have been topics in the past

you might find some info with a search

Its a "special" vehicle top secret, and until I get some answers can't be revealed..... It's a customers engine and until I have spoken to him I wil lnot be divulging the vehicle type it came out of and incidentally is going back into, however he has a Mini as well

Here's a manual for those engines:
http://www.instructi...rs/BMCminiT.htm

They were fitted to the BMC-Nuffield 'Mini Tractor' (funny name, eh? ).

I hope you know how jelous I am I want one of those engines.
There's a guy in Australia running one with bio diesel & turbo in a Moggy Minor Van
I once tried t find out more - with no luck at all...

I think it is redlined at 4000rpm? Might be tricky, even with a MPI FD...

Please keep us updated! Any more pics? Especially interested of a view to the combustion 'chamber's and pistons

That's got to be rarer than rocking horse droppings!

Never knew the A was manufactured as an oil burner - will folow this thread with interest!

Not that rare - as said it was fitted to the BMC Mini Tractor which later became the Nuffield 9/16 Tractor which later became the Leyland 154 tractor.

Whilst there are similarities between it and the petrol A series they are very differnet in reality - very few (if any) parts are interchangeable. As most engines of the era were designed in a similar way they all have similarities - look at the pre cross flow Fords they are similar in places to the A series.

As said, in a car I think they would be very slow and noisy. If geared for speed they would have bu66er all acceleration (unless you had a 9 speed box like the tractors!).

May be not so rare, however these engines where not fitted to the Leyland 154 that's based on the MGB 1800 engine

They must've changed after the Nuffield then - the Leyland was basically the same tractor but I guess needed modernising to 'keep up'. The Leyland stuff isn't old enough for me!!

I think the 950cc engine was only used in the first 9/16, then got a 1500 and finaly the 1800cc engine!? But then I know close to nothing about tractors

@Martin: Looks like it has 11 head studs? Do you have any more pictures of the engine? Eypecially of the head?

[MRA]

I have had a look at the manual, thanks Asphalt, I don't think that it is a 1500 though, as the person who has it says that it is identical at the block to (in this case) sump interface.....

Just imagine ........ a Cooper S diesel of the 60's

PS, I have a funny feeling that you will see this vehicle at a show near you.... well may be a show anyway

Regards Martin

[MRA]

Yes the block says 950cc Diesel........ 950D also used in Boats

Yes, your's is a 950cc But I think the tractor got a 1500cc engine at some point!?

Oh - that sounds interesting!

Would love to see a Mini with that 'hard' pre-chamber diesel sound
I'm pretty sure that would turn much more heads than any riced up Corsa

Martin, I think this sounds like a good adress for spares:
