Hi Gerard.

Could you tell me what kind of bearing is used in it? Both rear and front.  I assume
that the casing has stamping.
I don't want to start another thread on it because I asked already before but I can
not find it.

Never done it before, so can not  answer your question. Sorry.

Thanks.

Konstantin.
