How to remove this corroded headset race

gooseygoosey Posts: 133
Hi folks, this is the lower headset race in a carbon frame. When I took the fork out, the bearing cage fell out along with a couple of manky seals, leaving this corroded race in the head tube. How now to remove it? It's near as dammit flush with the inside surface and I can't get a purchase with a headset remover.

    I'm not certain but.. that's part of the frame and not the headset? So leave it in. Buy a new headset and see which bits it comes with. Then you'll know.

    Check your forks, is the crown race still on it?

    The bearing has separated into two, leaving the upper race stuck in the head-tube. Luckily the bearing isn't press fitted, so it won't be a tight fit, just held in by the rust.
    Use penetrating spray/fluid or even 3in1 to loosen the rust. Try just gently levering it out with a screwdriver. If that's fruitless, a blind/internal bearing puller (slide hammer) should work if there's a slight lip.
    Cheap generic bearing pullers can be found on Ebay for not much money. The quality isn't great, but bicycle work is very light duty.
  • This happened to a friend of mine on his Dolan ,got it out slowly soaking it with penetrative fluid and gentle tapping with a tiny flat head screwdriver all round . Was a couple of hours but it eventually came out
    Patience is the main key

    If you're not certain and want to confirm this is the case post a picture of the bearing that came out. Are the balls visible or did it come out with both races intact?
