I've found the hydraulic trick hopeless, if you do, then use an engineering tap of the appropriate size to screw in, then gripping the end with some mole grips or something, pull or maybe tap the grips to withdraw the bearing.

Rubber seal ???? Are we singing from the same song sheet ?

Ital engine and box, not a bush-- a needle roller bearing which has a rubber seal to ensure grease does not contaminate clutch I suppose. As I did indicate earlier. :wink:

Needle roller similar to the one in the photo attached:-[frame]Image[/frame]

As regards removing the outer casing - I would try screwing a coarse bolt into the remains of the bearing so it fouls/catches on the front and back lips of the bearing which were retaining the roller bearings and then continue screwing the bolt in, because the roller bearing is not blind the bolt can be fully screwed in against the back of the crankshaft and hopefully it will pull/push the remains of the bearing out of the rear of the crankshaft.
If the bolt will not pull it out try a pair of levers under the head of the bolt and see if you can get any movement that way.
I have just looked at my spare 1275cc 'A' Plus crank and it does not seem to be too hard a job to remove the remains of the bearing.
Make sure that when you replace the bearing it is set into the rear of the crankshaft by the correct amount.
If you can borrow one of these even better

I know the needle roller bearing alright - but not seen one with a rubber seal ....

Just looked again at the needle roller bearing in the rear of the 1275cc 'A' Plus crank and yes it definitely has a lip seal.

If you look carefully you can see the lip seal - whether it is rubber or leather I am not at this moment sure.

Oh well! Some do - some don't I guess.

Thanks Phil, but don't need that piece of kit. Seems, from your pic,that the outer must have come out with the rest of the bearing AND THE RUBBER SEAL! I would never have known that without your picture despite having 3 Repair Manuals ( 2 Austin Morris+1 Haynes) for this Ital. It was very rusty and completely broken up, so thats why I didn't realise the set up. Many thanks.

Well done
Just be aware that my picture featuring the rear of a 1275cc crankshaft is that of a modified 1275cc Midget crankshaft fitted with a first motion shaft needle roller bearing of a similar type to that fitted to the Ital.
The ESM link give a photo of the roller bearing.

Yes, I saw that and recognised it. Was more interested in the position in crank and now you have me doubting again.
I'll put a picture up tomorrow and ask on another thread. Maybe someone with the same combination can answer.

Below is a picture of the rear of the Ital crankshaft with bearing fitted.
The rear outer face of the first motion shaft bearing is set 12.3mm into the rear of the crankshaft from the slightly recessed part of the rear flange.[frame]Image[/frame]

Sorry to say it but it does look to be still in there :(
If you have a suitable tap that is just a bit more than an interference fit, screw it into the remains of the bearing until it bottoms on the rear of the crankshaft and continue tightening the tap and you may be able to screw the remains of the bearing race out.

Yes, tried that but have not got a big enough tap--mine only go up to about 1/2 inch, but i can get hold of one later.
Not critical yet--still waiting for new thrusts. BTW general question, what enamel engine paint do you guys use, spray can or brush. and what make please?

I use Glyptal inside the crankcases and just an ordinary BMC green engine enamel on the outside purchased from the likes of Frosts Restorations

Though I have found a tin of Hermetite Speedwell Yellow engine lacquer in the workshop so I might end up painting the spare engine that colour for a change. :D

Ok thanks, I'll have a look later as I want black for the block, red for the head as they were originally? How about Hammerite silver for the back/front plates--does it stand up to heat ok?

Edit---just looked up painting the inside of engines Chris, looks like there is 2 schools of thought on that?

If you paint the outside of the engine black how will you spot the oil leak source?

On the other hand, if it's painted black, how will anyone see any dirty oil streaks on it ;)

Good point, but I'm a born optimist--it 'ain't gonna leak :-? Seriously though purely for originality (Ital) and personal preference.
