Has anyone seen one of these before?
First thoughts are it may be marinised?
It seems strange that the dizzy hole is blanked.
Engine no. starts 10P
Very strange!
Any info much appreciated.

It's a diesel used in the small BMC/Nuffield tractors.

That's what we thought at first but can only find details of a 950 or 1500 tractor no 1100cc.
Also do you think that fuel pump would be man enough for a diesel?
Thanks.

Hello,

This looks to me like a regular block that has had some diesel tractor parts bolted on. Maybe someone tried to build a 1098cc diesel. Could that 10P engine number signify it's a prototype? Who knows!

I have one of the 948cc A-Series tractor diesels. As far as I know, they're all 948cc, and there are diesel and petrol versions. The diesel engine numbers start with 9T, and the petrol ones with 9TA. There are several important differences on both types of block, compared to the car engines.

1. The oil pump is moved to the back of the engine, near the fuel pump. It's driven off a jackshaft that goes where the distributor
shaft goes on a regular block. The block in these pics does not have this.
2. The head studs on the tractor engines are 7/16 instead of 3/8, there is one more stud, and they are all spaced differently too.
3. The dipstick hole and generator brackets are both on the opposite side of the engine on the tractor.
4. They have factory-fitted cylinder liners.
5. The crank is also bigger and heavier than a regular 948 crank. It looks like a short-stroke 1275 crank.
6. Rods and pistons are both much bigger and heavier-built than standard, although the bore and stroke are the same.

I haven't figured out how to attach pictures here, but if you send me a personal message with your e-mail I'd be happy to e-mail you pictures of my block.
(Yes, I'm trying to put this engine in a Mini, as a long-term project!) I can also send you manual scans if you need them.

Best wishes,

Ian
