Saw one recently. Very very rare it seems, but it's from the works. Anyone else seen one ?
Location: South West France
Sold one last year to an excellent austin 7 man on the south coast.
Should about be in his car by now.
He reads the forum.
If you ask nicely he might even put some pics up for you.
Very curious haow the crank oilways arranged. Surely they would not attempt to feed all from the lomg suffering centre main, and it is a long and winding road from the front, although I guess for modest flow pressures ultimately same as with 2 bearing. Does the crank have the external radius hoops?

I have some pics of one from a Grasshopper:

The G word. R
If the bes were all fed from the front would involve yet another return of oil to the axis. Maybe the web drillings to surface were to avoid the axis.
Surprised that a simple exhaust manifold retained. If nothing else separate pipes reduce the heat applied to exhaust valves, which, being distant from water on one side, have a hard life.

It looks as though the Ulster type web transfer port holes have been blanked off. Why?

Here is the 1947 article on the Grasshopper engine. I've been trying to research the pressure 3 bearing and Nick Turley's interesting thoughts from another thread sit against what evidence I can actually find. I wonder whether anyone can come up with a pic/evidence of a three bearing pressurised engine that they rebuilt for a Speedy in Germany.. and has the relieved sides for the larger crankshaft?
The evidence (known engines) seem to suggest that:
1. the pressure fed 3 bearing is 1 5/16" and smooth sided, and the same as the standard non-pressure engine casting with the exception of no oil jet drillings, and a larger aperture for the high lift camshaft.
2. one crankcase has been numbered 1A; one other is remembered as 9E...
3. [Nippy 3 bearing crank] is pressurised through centre main alone, not as per the Grasshopper spec article to fornt and middle.
There has been some discussion on the drivetrain height i.e. on some crankcases the feet being different. This could be a red herring, unless anything emerges to support.
Can anyone elucidate further with evidence?
Doug Kiddie made a couple of 3 brg cranks,probably 15 years ago,one was for a german customer I believe.

He sold out to arrow in Hinckley a long while ago.I would guess they would have drawings from then.Do you want a photo of a crank?
No, I want to know if by any chance he ever made a 1.5" rather than a 1 5/16" one! i.e. to see if that story is a red herring...
The german connection seems too close not to explore with Nick's story.
Presumably someone may have the German owner name if it was in a Speedy, too.
Arrow sadly dont have the drawings any more...
I don't know If Doug kiddie kept the drawings.
He is kind of still in the crank business.
He used to be in the next village to me.
The only person I know who will be in contact with Doug, is Peter Pearson.
As Doug organises the counterbalanced cranks for Peter and myself. Same as the kiddie crank I had made were through Doug.

Another little item of interest.
When Doug was running kiddie engineering in sapcote, he was making cranks for Jordan F1 cars.

Are you in contact with him? The question is, was it a special for some specially converted crankcase, or are we missing some vital information on a rare part that has been overlooked up till now?
i.e. could a 2 bearing pressurised 1.5"crankcase be converted to three bearing (and if so, why would one)
Nick's memory is of a case with relieved - unflat - sides, so no point questioning whether a 1.5" could spmehow fit in a straight sided 3 bearing case....
Peter Pearson as Tony has mentioned earlier is the one to ask,I believe they are friends.
All I remember was he had made one for a German client who was involved in other motor sport,There was a spare on the shelf and I bought it for one of my cars running a 3 brg engine.
I can't see why it wouldn't fit in a standard 3 brg case apart from line boring the centre main for appropriate shells and actually feeding it in.Building an engine,3brg with extra block studs would be really strong and smooth.
Do you want a photo ?
So you are saying that a 1.5" crank WILL fit in a standard crankcase...?
We still have the issue of the German car having a relieved crankcase.
Is there any difference in 2 and 3 bearing engines that would mean that a 1.5" crank will fit a standard 3 bearing case whilst a 1.5" 2 bearing crank wont fit in a standard 2 bearing case? (i.e. why presumably why they made a different 9E crank case in the first place...)
Curse of photobucket! if you email it to me I'll upload it in wordpress and get it up...
You say "mag c/c"... does that mean its NOT possible in a later dynamo/distrib crankcase?
Likewise, is it possible to change a 2 bearing sports crankcase casting to fit the gubbins for a centre bearing, without extreme hassle?
No what I mean is if you can get a 1 /2" crank in a case made for a 1 1/8" then it should be possible.Lots of people had fitted 1 1/2" cranks to coil c/c's.
As an engineer I would say it's impossible ,and unnecessary to make a 3brg out of a 2 brg,I don't think I could be proved wrong.
Many have gone the opposite way boring out the 3 brg case to fit a 2 brg crank though.
If you wish email me you phone no.
all clear now thankyou!
Oddly, it seems some may be able to see the photo? I certainly can't!
It was up for a few hours Jon,Can send one via Ipad if you haven't seen it.
Waiting for daughter to come round and dump photobucket.
Have just caught up with this thread.
I will contact Doug and establish if he still has any details and maybe drawings.
Just to complete the picture, when I first met Doug he was making cranks for Jordan F1, Judd, Hart, Arrows F1, Mclaren F1, Walkinshaw Racing and all Mercedes competition engines. I still feel proud that he personally designed my 100% counterbalanced racing cranks.
As soon as I find anything out I will get back to you.

Here we go, from A I T S!
For info, Nick Turley also recently said "There were some 3 bearing 1 and a half cranked engines, we put one in the German Speedy as its engine was missing".
He's going to try and get a photo of the engine.
I have a 3 bearing pressure fed engine to sell , it came with my nippy many years ago .
The engine is stripped down , I had the crankshaft crack tested and it was fine .
aluminium sports sump with the 9 E cast into it , tulip valves but 3 vales are missing in the Block , Dante aluminium sports head , sports canshaft.
Crankcase is un drilled where the oil jets normally go .
All the bits seem to be there apart from 3 valves.
White metal looks good in the con rods and crank looks fine .
con rods are for floating pins .
Strange that they used white metal in these engines, i thought 3 bearings would have had shells.
I have kept the nippy carb , manafold and head as I am using them on my nippy.
I am looking for offers over £3000.00 for this very rare engine that must be a late nippy or speedy engine.
cant see how to attach a photo of all the parts laid out.
