I was wondering about that too…how do you get those snap rings off?

And do you have to completely remove the wheel to change the tire or is it
possible to remove the seat and pull the tire up through the split fork
crown and stem?

Putting those snap rings on is pretty easy, but I’ve never found a good way of
getting them off.

  1. Generally I mount the frame in a vice or other solid holder, if possible.
  2. Then put on a pair of goggles.
  3. Then jam the ends of two sharp screwdrivers together at the gap in the ring,
    twisting them against each other to push the two ring ends apart.
  4. After a whole bunch of tries, you can either
    a) Use your third hand to stick a third screwdriver under the middle part of
    the ring if it’s lifted up, or
    b) Listen closely as it pops off and finds the remotest crevice of the room
    to settle.
  5. Go find it.

As for dismantling the hub, unless you count the bearings it’s all one piece.
The bearings might need replacing, but the cycle will work with or without new
ones. For the axle, you usually can’t tell if a failure is going to happen until
it’s most of the way gone (then you might see cracks). You could look for bent
flanges or damage to the tapers or threads on the axle ends.

It’s surprising how many people ask this question. All you have to do is take
out that one bolt.

Re: Schwinn hub

There is a special tool designed to for these snap rings. I have always known
these snap rings as “cir-clips” but I am sure we are talking about the same
thing. It’s a C-shape clip with a hole in each end ?

If you visit your local auto shop I’m sure you could find a cheap pair.

They make it so much easier and they don’t go flying across the room like if you
use two screw drivers.

As for removing the bearing from the housing, use a “puller” if you want to do
it correctly and not damage anything. For this job it could also be used to
assemble the new bearing in to the housing also. You can pick up a small puller
when you go in to to get your cir-clip puller from the local auto shop. Just
tell the guy you want to

What the hell are you guys doing to your unicycles that is causing axels to fail
?

Re: Schwinn hub

There is a tool available for removing the clamps (c-clamps?) that hold on car
door handles (window winders, etc.).

After using the three handed, two screwdriver method that John described, I
found it easier to use the special tool. I used it on a car though. I’m not sure
if it is transferable to unicycles.

Ask at your local auto supplies shop as it may work for unicycle clamps too.

Sorry, I couldn’t think of anything quotable.

RE: Schwinn hub

Mark, The clip or ring is in fact C-shape but there is no holes at the
end. I do not believe from what I have heard that the axle is bad. As
old as it is I am sure the bearings have seen better days. This has
never been apart since it was new
( along time ago).

RE: Schwinn hub

Thank you for the help. We will give it a try and let you know what
happens with the axles and the bearings. Paul D. Spencer

Re: Schwinn hub

Hard to say without seeing it so I would recommend getting one out and taking
to a place that sells tools (such as an auto accessories shop) and see if they
can help you.

Maybe it has some type of notch at each end to grip and open it up from??? If
not then I would definately see about replacing them with cir-clips and getting
the special pliers for working with these.

Sounds like a wierd set up to hold the bearings on but then I have never pulled
a schwinn apart (or ever seen one for that matter). While we are on the same
track, if your replacing the bearings (I’m assuming that they are a single piece
construction and not the seperate balls that used to be used in the old
bicycles) then I would recommend getting fully sealed bearings(you can’t
actually see the balls as there is a plastic seal in between the inner and outer
rings). These will never need to be greased under such a light application
(bearings can take huge loads) and generally give a nice smooth operation.

The bearings I have seen in unicycles (mine and pictures of others) all seem
pretty standard. You should be able to pick these up from a bearing specialist.
If you look up bearings in the phone book you’ll find some where that
specialises in bearings and they hav a huge range. Just take in your old one and
tell them you want a fully sealed unit. They will probably be cheaper and better
quality from there than any bike shop.

Mark.

RE: Schwinn hub

Thanks, I think sealed bearings does sound like a good idea. I will get
back to you and let you know how I made out. I will also let you know
if there is a tool for pulling these c-clips off. I do very much
appreciate the help.
