This can't be good ...

In an attempt to fit a new coupling I tried to remove the nut , obviously didnt debur it enough and the nut stuffed the thread after about 3-4 turns then stopped , now I need a new shaft which so far unable to find ...
Also need new nut but I found 1 of them.

Been a long day

why not re thread it then use a smaller hub nut? i would look at trying that first if its going to be a nightmare finding a new part.

If you do re-thread, it would be worth having it reverse threaded. Then if you fit it to the drivers side it will be self locking

how about using something like that: http://www.fi500.de/detail.php?id=768

or that: http://www.fi500.de/detail.php?id=787   (seems to fit your car)

could also fit: http://webshop.fiat500126.com/?PATH_INFO=/katalog/artikelinfo/804-1-radnabeachsstummel_hinten_fein_verzahnt.html&

 

but you have to care about whether it fits your car...

So luckily for me I know a few handy people and someone has already machined it down , run a new thread on it with a Nyloc and its back together and working , couldnt be happier

Best of all the new engine actually has oil pressure and my 3rd is back !
