  • Best method for removing a seized bottom bracket: you will need a bench vice, bb tool (one designed for use with an adjustable, eg Park BBT-2), graphite penetrating oil (wd40 if not) and a friend with a keen sense of balance.

    1) spray penetrating oil liberally into bb shell. leave for an hour or so.
    2) mount bb tool securely in bench vice so the spined section is facing upwards
    3) place frame so that the seized bb cup aligns with the upright bb tool (eg so the frame is lying horizontal/parrallel to the ground)
    4) Get friend to climb up and stand on the other side of the bb shell, thus applying the requisite downwards force to keep the frame in place.
    5) Rotate the entire frame, this will give you a shedload of leverage to remove the cup. If this doesn't work nothing will.

    If you don't have a lot of space around the bench vice you may need to just use half-turns and remount the frame several times, at least until if is free enough to use an adjustable.
