Changing a headset is something you don't need to do often,
but why not do it yourself? Sure, you could roll into a bike shop, and pay $25 (maybe
more) just for the installation, but doing it yourself is so much fun!
Recently I found myself in need of a new headset - not
because it was bad, old, or ugly, but because this headset was missing the top
cap, and it was simply cheaper to purchasee another headset for $9.
Okay, so we are going to swap out a headset on my Frank-en race bike, in no less
than 30 minutes, using homemade, specialized tools.
Step 1: Get your
tools together
Here is what you will need:
1. Standard hex wrenches that you would use to dissemble your
bike
2. A hammer (any kind, of reasonable size)
3. A 3/8 inch bolt (as long as possible), with or without a head, threaded as
far as it can be (this could be slightly larger, if it's all you can find)
4. Four (4) thick washers for the bolt mentioned above, and at least 3 nuts that
fit it (Two to lock the washers on, one side, and one to tighten on the other
when you press the headset)
5. A copper or aluminum pipe (copper will bend better
without breaking, but I used an old seat post made of aluminum that I put a 3 inch
cut in down the middle)
6. A hacksaw
7. Two adjustable wrenches, or fitted ones to tighten your
frank-en press
8. Grease, of some sort (I use bearing grease - it's red, yay!)
First, make a 3 inch (or so) cut down the middle of your
pipe/seat post.

Then splay it out a bit, so it can reach both sides of the
inside of the headset cups (this is the special tool). I happen to be using a long screw driver for this task.

Step 2: Tear apart the frond end of the bike
1. Remove the front wheel, fork, handlebars, and any
associated cables/spacers
2. Keep an eye on the order your parts and spacers are in for re-assembly. Document it, if neccesary

Now your bike should be like a "T-Rex" with all the
junk in the trunk, if you will... and you are ready to remove the old
headset.
Step 3: Remove the headset
1. Be sure everything is removed from the headset, sealed
bearings, cages, etc
2. Use your new tool!
Place the removal pipe into the head tube (it should just fit through
the cup), and you should be able to catch the lip of the headset cup
3. Once you can feel it catching the lip, gently tap the
pipe on each side so it removes the old cup evenly (this may be difficlult,
depending upon how old/what material your frame is. Mine was easy, as I have a
fairly new aluminum frame)
4. Repeat this on the other cup, and you should end up with
an empty and clean head tube
1. Unpack the new, awesome or cheap, or awesome AND cheap
headset! Take note of the top and bottom. Usually this does not matter, but sometimes it does. The most inportant part is in the details. Use
the crown race, and seal on the bottom, and the top cap and star nut on the
top (for this how-to, I re-used the
existing star-nut, and my crown race, as they were identical to the old headset. I'm saving the new crown race for a new fork someday)
2. Let's get it on.
Place one cup on one side, and then use your "press", to
slowly tighten the cup. Be careful to
check every turn, and make sure that the cup is going in straight, it will want
to move around, and you will need to adjust your tool slightly to get it
"right"
3. Place the other cup in the head tube, and repeat step
number two above. You should now have a
head-tube with 2 empty cups (see photos below)
1. Let's put the bearings, the seals, and everything else
back together. It should go in this order - First, put the lower bearing and seal together on the fork crown, grease
the bearing, and place the fork into the bottom cup - bearing-seal and all. Then place the bearing into the top cup,
around the fork top, grease the bearing, and drop on the remaining seals and top
cap
2. Replace the handlebars/stem/spacer
3. use your stem cap to tighten/adjust the headset. It should be firm enough to the headset has
no "play", but does not bind
4. Tighten everything
WELL
5. Be happy - you now have a new, installed headset!

Notes and musing:
This is not all inclusive, and there are details you may know
better/do better than me. There are
somewhere in the range of one million tutorials on this if you search Google,
everyone does it slightly different, or thinks about it differently, etc. Your
mileage may vary.
I have done about 10 headsets at this point, and I find that
steel frames, particularly older ones are much harder to get headsets OUT
of. My Bianchi took monster truck force
to remove the headset. There was some bleeding, cursing, and anger {G.E.'s note: He's not lyin' about this one folks!}. Always take
your time, and do it right. When in
doubt, go to a bike shop you trust. They have awesome tools. I simply like doing things myself, and
sometimes like the pain too. Lastly, If you think you are doing it wrong, or don't feel
safe, don't even start! I am rather
cavalier, and confident with bicycles.
Never compromise safety, ever!
Speaking as the observer of this project, I will say that it didn't look so horrible, and I even thought that perhaps I, the mechanically-inept individual in the house, could manage it (under the right circumstances). It didn't take very long at all (after all the tools were found - as the mechanic didn't follow his own advice and line up the tools first). As a visual learner, I appreciated being able to see the headset removal/installation process, and hopefully, this will help someone else out there who's looking to do more bike changes/repairs for him/herself.

I would like to add, that there's usually a better/more efficient way to do it (no matter what I seem to do), so If you have a better way, chime in! I'm sure it won't be my last headset..
ReplyDeleteLOVE your blog. Just discovered it - stumbled upon it from some other bike-related site. I made myself the very same headset press a few months ago and it works great. Bought the cup remover though... you're an inspiration! Keep up the great work.
