Install a headset in a bike

Step 3: Remove the old.

I had to remove the old headset. I did this by tapping out the cups using a LARGE screwdriver and a hammer. You don't want to hit it on a funny angle. If you don't have the screwdriver on straight it will gouge the cups. So tap them out carefully.

Don't hit the screwdriver up towards your face. If the screwdriver goes awry you may hurt yourself.

Park Tools makes a really nice tool for this job, about $30 USD I think. I personally use a set of handlebars, grips removed, as a sort of slide hammer.

The preferred method is to use a screwdriver or punch working from the inner part of the head tube, as shown above, pressing them outwards in a circular motion to avoid yoking out the head tube, where the press-fit of the cones will not be so effective thereafter. Try to tap them out as evenly as possible. A safety measure is to tie wire or string through the headset to prevent cups from flying out of control once they break free...
