    I need to purchase one, the largest I have is 1-3/8".
    Would someone please save me the time & effort of pulling the bits off to get to it & properly measure the size of the socket needed to remove the harmonic balancer / crank pulley?
    Trying to get a caliper on it from the top it seems to be either 44mm or 45mm...

    Thanks!

    36mm will do the trick...

    Nothing on your Ferrari is AF/UNC/UNF - its all metric - so put those AF sockets & tools away before you break something ! :)

    (36mm as the man said)

    Actually, there is one application of an SAE fastener on the 3x8; the tie rod end lock nut. But that's a topic for another day.. ;-)

    That's 1-13.35/32
    Just a smidge smaller than 1-7/16.
    Just a smidge bigger than your 1-3/8.
