    CRANK PULLEY!!

    Hi - Can anyone tell me the torque setting for the crankshaft pulley and also the bolts which connect the torque convertor drive plate to the flywheel?

    My WSM states in Kg/m

    Securing Flywheel - 3.1
    Securing Flywheel to Crankshaft - 8.5
    Securing Damper to Crankshaft - 20

    Not sure if I've lost something in translation but just wanted to check

    Many thanks

    That should actually be "Kg-m" (kilogram*meter), not Kg/m.

    1 Kg-m = 7.23 lb-ft so just multiply them out to get them in lb-ft (and those values seem reasonable for the sizes of those bolts). I use this website for converting units:
