Crank bearings good or bad

Any tips on getting the paint of the cases?? mine appears to have been painted silver, then black.  the black comes off really easily it just wipes off if sprayed with WD40 or a bit of petrol. but the silver seems to be far better quality (assuming this maybe factory). I was thinking possible paint stripping??

I used Paramose Paint Stripper - it's for trade use only as it contains some nasty chemicals that work. Modern over the counter stuff like Nitromoors are imho useless.

You will need to use the right safety gear, right mask, eye protection plus appropriate long chemical resistant gloves. It's nasty stuff hence the restriction on retailing.
Once down to bare metal after washing off I used wet a dry to remove any bad surface oxidation.

After painting the cases silver - oven baked to cure.

Has anyone got an idea as to were I can a 57mm ring set from as whoever put the engine back together last time left this and the 52mm one out. Which explains why drive socket seemed loose and moved in and out from the crankcase as the entire shaft was moving 🤦.

It's showing as out of stock on CMS website and DS don't list it. Done a search of the web and nothing comes up where it's in stock

Bryanj:
I think i have a 550 bottom end lying about and may be convinced to split it
