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.

Problem solved Phil. Found (to my total amazement) an ex Cowley apprentice who has a restoration business in our (large) Village. He has lots of old factory tools, and whipped the offending bearing outer out in minutes.
Then spent the rest of the morning reminiscing and proudly showing me pics of his efforts. All for a fiver on the spot!

Thrust washer problem also now solved. Received new set yesterday which fitted perfectly first time. Crank spins easily with correct end float. If anyone is interested they were Mahle. Also bought some engine assembly lube, just the job for retaining cap thrusts in position when fitting.

Another small but annoying problem. I need a "plug" to blank off the 'ole in the inlet manifold, servo pipe take off.
Where would i source from--Pipe thread (plumber) or ncf engine part?
Have tried usual supplier, but no joy.[frame][/frame]

It's 5/8" UNF. http://minispares.com/search/classic/ma ... 0plug.aspx

Super, Thanks Roy.

Please be aware that some of the vac take off pipes on BMC/BL manifolds are 5/8" x 16 TPI UNS and not 5/8" x 18 TPI UNF as per the link above.
I would advise that the TPI is confirmed before trying a 5/8" x 18 TPI blanking plug into the hole.

The correct blanking plug for a 1300cc Marina/Ital inlet manifold is Pt No: ADP210.

Thanks Phil, but the link that Roy put up, took me straight to the correct part no--fortunately,or maybe he searched for A plus specifically. It's ordered, but surprised at the POSTAGE cost, pity they didn't have one in stock at Harrowgate depot--I'm going there Monday, so had to order from head office.

It should fit - Minispares should know what they are doing. I have never come across this UNS thing - nor do I know where you would get such a plug.......

5/8" x 16 tpi Unified National Special (UNS) threads can be found as the thread of the crankshaft pulley bolt/starter dog, the threads in the head for the bypass hose adapter and can also be found on the male/female inlet manifold vacuum take offs on various BMC/BL manifolds. There may be others that I have yet to discover but those listed above are the important ones.
Fortunately I do have a 5/8" x 16 tpi UNS tap to be able to clean up those threads if required.
As regards Mini Spares - they are very good and I do have quite a few spares off them but the listing for the blanking plug (Mini Spares Pt No: 5-8UNF) for the bypass in the cylinder head is listed as 5/8" x 18 tpi UNF when it should be 5/8" x 16 tpi UNS.
Thankfully Osselli supplied me with a batch of 5/8" x 16 tpi UNS blanking plugs many years ago for blanking off the bypass hose threads in the head and I do have a few left

Looks like you're right Phil, received the plug today----wrong thread. Have Osseili got any more (they are not listed) or do I wrap tape around the standard bolt and fit a jub clip around that?
Remember: it's only to go on the test rig so will not be needed when back in the car.

What do Minispares have to say about it?? If it was just for a 'test rig' - i would have jammed a cork in it!

John
If it is a 5/8" x 16 TPI UNS and you have a spare 1275cc crankshaft pulley bolt I would use just that to block the hole so enabling you to run the engine.
I do not know if Osseli have any more 5/8* x 16 TPI UNS blanking plug you could always give them a ring. It is a long time since they supplied me with the ones I have.
If you get absolutely stuck send me a PM or call.
Phil

Haven't got one of those, but just tried a temperature sender in there, and its fine, as you were alluding to earlier.
I've got a busted one somewhere, I'll dig it out tomorrow.
Cork???? Nah dont think so. People will think I'm a wino!
Thanks

Hi,
Thank you for your reply. We have had our technical colleague look to this matter of the ADP210, with the manufactures. An dthey have returned with the reply,
I have checked with the manufacture, they are definitely the correct thread size (18 tpi) however the zinc plating is quite thick making them ever so slightly oversize. If you use a spanner to tighten it down they should be ok.

If you wish I can send you 5-8UNF plug screw as an alternative solution, free of charge?



Heres the answer chaps ---what do you think? It's still not the suggested thread. Don't want to wreck the manifold. Do I try their alternative? Haven't found the scrap temp gauge sender BTW.

John
I can confirm that blanking plug ADP210 is and should be 5/8" x 18 TPI.
Temp transmitter in the head is also 5/8" x 18 TPI.
Both the above checked with a tap and die/die nut.
I would not force it into the manifold as you could crack the manifold.
I can also confirm that the Mini Spares blanking plug Pt No: 5-8UNF will fit the hole in the manifold but is no good for the long term as the manifold hole is straight through and the blanking plug 5-8UNF does not have a head to stop it screwing all the way through as per ADP210; it also has a parallel thread so will not grip the walls of the manifold when tightened as a tapered blanking plug would do.
John
I have sent you a PM.
Phil

Seriously - you said this was just for a 'test bed' - a cork will be fine !

Yes, of course Roy, but have to think a little more long term, and may decide to not bother with servo when brakes upgraded, or fitting on "spare" engine in future, so may as well sort it now.
