    Any idea how to remove the drive side BB so I can get rid of the old e-mount chain guide that has welded itself to the frame?

    It is currently soaking up the oil and penetrating fluid hoping it will move in the morning

    Which way are you turning it to loosen?

    You’re turning it clockwise, right?

    I have the proper tool.

    On the drive side, it is the normal thread pattern right? Lefty loosey, Righty Tightey?

    Please confirm because tomorrow I will move on from muscle power to a 4lb lump hammer.

    Thanks

    Just read the link – Is it a reverse thread?

    Please let me know for certain

    Is it a steel frame?

    If so, soak in coca cola (or pepsi)

    The phosphoric acid should help free it up

    Also helped enormously by turning it the correct way too. 😆 🙄

    For “Normal” BB to undo, turn towards the front of the bike.
    A tip passed to me many many years ago.

    Smooth shifting and silent loveliness

    I had forgotten how nice new transmission shifts are and Shimano is so easy to install and set up

    It’s always DRIVEL:

    DRIVE (side) = (equals) LEFT (hand thread) 8)

    Hth – in the future

    but what if you put the spanner so the handle is down at the bottom?

    the way I remember it is by remembering that if a BB jams it will undo from the frame under normal pedalling and push out onto the crank arms instead of tightening and jamming into the frame.

    Once I had removed the BB I saw some little writing saying TIGHTEN with arrows pointing the right direction to tighten the BB. If only they had ones saying loosen I would have been alright!
