    B34 Crank Bolt ( socket size?)

    Do you know what's the mm size for the B34 front main crank bolt?
    It's much bigger than 30mm, i need to find out the socket size to buy.

    Thanks!

      32 sounds correct, it's a big bastard. Also, the torque spec is around 325ft/lbs so you MAY have to wait until it's in the car and connected to the transmission before you can properly torque it.

                my bad. hope you kept the receipt.

                if you have access to an impact, that should pop it off no problem.

                only took one hit to get that bad boy off.

                  It is also very close on the standards scale, I want to say 1 5/8" but not positive. I had one huge socket laying around and it just happened to work.
