Miele Bike -- Removing the Headset to move it over to the Schwinn Paramount

Need to remove the goose-neck & handlebar to be able to remove the headset.

The Shimano 600 headset uses these unusual nuts but a regular 32 mm headset wrench fits.

This long Allen had screw is what holds the goose-neck in place, inside the fork tube. What you should do is to loosen it a few turns then it the head of the bolt with a plastic hammer to push the tapered nut down and out of the bottom of the goose-neck.

I was able to get the locking nut at the top of the goose-neck loose. Took quite of bit of force...

I already had this Shimano Headset wrench (32 mm). It worked well.

Although the goose-neck bolt & nut were loose, the goose-neck did not want to come out of the fork. I'll have to push it out from the bottom of the fork. First, I need to remove the front brake. I loosened the Allen had bolt in the middle of this picture to remove the front brake assembly. It came off without a problem, fortunately.

I was able to push the goose-neck out from below using a hammer and something to push with. As you can see from the dark staining on the gooseneck, it was corroded and kind of stuck to the inside of the fork...

The goose-neck is aluminum and the fork is steel. So, it's susceptible to galvanic corrosion (corrosion caused by dis-similar metals in contact, especially aluminum and steel...).

Here's the setup I used to "push" the goose-neck out by applying force from the bottom. It's a long 3/8" socket extension with a deep 9/16" socket on the end. This is the largest socket that will fit into the hole at the bottom of the fork. Because the socket is smaller than the goose-neck, you have to make sure that one edge of the socket is pushing on one edge of the goose-neck.
