I changed my bearing way back and as I remember you need to drill out the retaining rivets (to be replaced with screws/nut + locktite) Take the bearing into a proper bearing shop, should be able to get a replacement. You might have to warm the ally end casting to get it off.

Result! Nice to keep all the original bits. Parts like starters and dynamos have dates on and are part of the vehicles past.

As you probably know the C39 brushes are a different size to the C40 brushes
