    Do you have the service manual?
    Have you contacted the frame manufacturer for one or asked how to remove it?

    If you are prepared to risk damaging the frame, then support the other side on a block of wood and cloth to avoid paint damage, heat the link with a hair dryer (aluminium expands more than steel. Assuming the pin is steel. Can be tested with a magnet), then using a hammer and a drift gently tap the pin and look carefully for any movement

    I suspect that all the hair dryer will do is knacker your paint work. The pin will probably just tap out, however it might be directional.

    No. I've had a blow torch on a frame before. You need common sense and know when to stop before paint starts to be damaged.

    If a hair dryer is a worry use boiling water.

    im sure the taper is visible in the top picture so it was tapped in from the bottom picture side.

    Tap the tapered end to push it back the way it came from in case it is directional.

    When I go in my mates bike shop he’s always got the hair dryer out Not. If you need to start heating something to loosen it, you got major problems. This is Just how do you get this pin out, not that it’s seized in place.
