Hello Everyone

I am instaling a Miche Primato BB, the first ever, and I seem (no no not my first BB just my first Miche) to either misplaced any dierections or it never came with any.

my question is quite simple, does it matter which way the cartridge goes in? other than a model and size I see no indication of how to insert it. it is a 107 symetrical spindle so no help there. does this little black O ring looking thing have to one side in particular?

also any idea what I should torque it to? BTW not that it matters it is an English BB

thanks a bunch

OH I did put this in the Mechanics forum too. maybe one of those youg hipsters has more ecperience with these for SS/FG bikes
