Well my project today is I'm gonna go ahead and change
the freewheel on this bike.
This has got a Sachs freewheel on there and it's a bit worn.
And shifting is not too great. So I'm going to go ahead and put a brand new
Shimano freewheel. What a freewheel is,
its a self-contained little unit. It screws
onto the hub. So it's got little threads back here. And
it's got the whole bearing system inside there
so it spins on there. And it's got pawls.
So what it does is, it allows it to spin free in one direction
but then catch in the other direction so it turns the wheel. So that's what a
Not to be confused with a cassette in which
the little bearing and pawl stuff
is in a part...another part that is attached to the hub called a free hub.
But I'll probably do another video on that too.
So the first thing I want to do is remove the wheel.
And for ease of use I've got the chain shifted to the smallest
ring. So go ahead and pop this down. It just makes it a little easier to put the thing back on.
Okay, I've got the wheel here. I wanna go ahead and remove
the skewer. And get the spring.
And put it out of here. And go ahead and put that aside.
Don't lose the springs. Now depending on what brand of freewheel
you are removing and installing, you are going to need
different I tools. If you look right
in here, there's like little splines.
You might be able see it on the the new one a little bit better.
See, there's little splines in here, and so what you are going to need
is a tool that's going to fit those little splines.
Here's like a few of the different freewheel tools that I have.
Here's one has splines on it.
And then these ones have little notches.
Some other brands of freewheels also have these little notches these fit into.
The Sachs also used the same one here.
This is a Park Tool FR-1.
These other ones here are also made by Park Tool.
These tools generally cost,
usually under about 10 bucks. You can find them for maybe
like 8 bucks at your local bike shop. Anyway this tool
what it's going to do is it's just going to slide right in here and mesh with those little splines in there.
Okay so I have the tool in there
And one thing you can do is you can put the skewer
back through here, and have it actually go through the tool
to help hold the tool on. You don't want to have it clamped real tight. You want it a little bit loose so
it gives it a little room to move out. But I
rarely ever do that. Not on this kind.
On the other ones that have the little notches that come out...
the other two types of tools, I usually do. But on this kind I generally don't.
So slide this in here and I have a big Crescent wrench.
and I'm going to fit this on here. And what I want to do
is turn this
counterclockwise. Now if this freewheel has been on the bike for a while,
what happens is, this is turning clockwise it's actually tightening this
thing on. So if this has been on the bike for a while....
these things can be extremely tight.
And you may need more than just a wrench to remove it
So what I am going to use is
a big cheater bar.
So I am just going to slide this over the Crescent wrench here.
to give me more leverage. And
usually I will just hold the wheel. If its real
tough I can actually kind of brace this up against a wall or something.
I rarely have to do that. Usually just
do this and break that thing loose.
And once you get it loose then you can just
unscrew this off. Just turn this tool.
It'll come loose. There.
It comes right off. And so there's the threads
that the freewheel screws right onto.
Okay I am ready to install the new freewheel.
Just slide it on here and
turn it on. Get the threading started.
and it should thread on pretty easy. Then just go ahead and spin it on.
Until it's tight there. Then you can take the tool
slide it on there.
Use the wrench to go ahead and
tighten it on there. I don't need the cheater bar to
tighten it. I just use the wrench to tighten it on there.
And that'll be good enough. As I ride it
the freewheel itself will go ahead and tighten itself on.
Now I wanna reinstall the skewer.
So I just slide this up.
The lever goes on the side opposite the freewheel. Slide this on here.
Get that started.
Now I wanna reinstall the wheel.
Since I had the chain on the smallest cog when I pulled it off
I am going to go ahead and put the chain on smallest cog putting it back on.
Slide it back up in here.
Tighten this on here.
Like that. Then just go ahead and
test it, make sure everything works good.
