  1. I would like to know, please, if there is any good way to pull headset
    crown races short of buying a crown race puller, which would be rather
    tiresome for one headset's worth.

  2. screwdriver, mallet, gentle tapping, and you can *usually* get it off
    w/o damaging it.

    Installation with a length of PVC pipe is highly recommended if you're
    going for a true high-class job. :-D

    It isn't a puller but rather a pusher and the tool is relatively
    inexpensive:

    Oops, Park Tools was a bit misleading in that they show you a remover
    for frame bearing races when you ask. You probably want a device that
    looks more like this:

    Actually, if you don't mind the race getting some mild blemishes, you
    can beat it off the fork with a flat faced punch (drift pin) by
    alternately driving the front and rear part from the underside.

  5. i create a DIY!
    a walmart machete will "pull" the crown race.
    heat the race till it smokes
    insert machete edge bewteen race and fork seat
    tap dull machete edge with wood block
    move to opposite race side-repeat
    then 90 (why no degrees on the keyboard?) repeat
    then opposite then as necessary
    then the race will work loose with vice grips after heating -more pull
    than turn please to avaoid gaulling

  6. uh-let the race cool following the machete work
    spray/dribble with light lube-pcblaster is recommended but red finish
    line unshaken is good
    then turn-pull with vice grips.

  7. What they all said plus - the fork may have two indentations to fit the tool
    / screwdriver / punch as a starting point to work it off. Once it moves a
    bit it should come off easily by "rocking" it side to side with your tool of
    choice. It shouldn't take a lot of force. Go easy, use patience.

    I've had no problem getting the majority of them off using a bearing
    splitter plate, a block of wood, and a hammer. Position the splitter
    plate below the race, rest the plate on the open jaws of a big vise,
    protect the end of the steer tube with a block of wood, and tap on the
    wood with a mallet to drive the steerer through the race. As long as
    there's an accessible shoulder to grip under the race, it works.

  10. a bearing splitter plate are two machetes bearing down on each
    other-the machete costs 7 bucks and can be used to defend the camp
    site-most folk turn white at the sight of a waved machete.

    Rubber mallet. "Tap" on the front, then back, to work it off the crown.

    Well, now I'm confused. Having looked at these photographs, both of these
    devices appear to remove the same thing from the frame. What I've got is
    what is left over when a threaded headset has has everything screwed to
    the fork unscrewed and the lower half of the lower bearing removed with
    the fork.

    Sheldon's bicycle glossary suggests I am confused about terminology; that
    a "crown race" is what is left behind on the fork (next to the fork crown)
    and that what I actually want to remove are the two frame bearing races
    which are stuck to opposite ends of the head tube, and so the Park Tool
    link depicts what I want. Is that correct?

    That's the inexpensive tool that removes the headset cups.

    Unfortunately, he wants the expensive-looking tool that removes the
    crown race from the fork:

    http://www.parktool.com/products/detail.asp?cat=50&item=CRP%2D1

    I think G Daniels has the best idea with his cheap-machete concept.

    That, or this is one of those 10-minute jobs that may be worth paying a
    shop rate for, at least if you're dealing with something vulnerable like
    a carbon fork.

    This tool is for removing bearing races from the head tube of the

    Well that is what confused me so I listed both tools. Yes the fork
    crown race is the head bearing race that is a press fit on the fork
    crown at the base of the steertube.

    I drift them out with a short length of good-sized copper pipe.

    He was making a joke (a pretty funny one, too).

    Hint: it is a talent he was born with.
