Removing a stubborn fixed cup
from a bottom bracket can be a real bear. Especially if it's been on there for a
long time.
And I'm gonna show you some tricks of how to get this thing off.
I already have the adjustable cup removed from the other side and have
everything cleared out from in there.
So what I am gonna do is I'm gonna take some penetrating oil and spray it in
from the back side here and try to get it all
coated into the threads of the fixed cup here.
And let that soak in there for a while. Okay now to remove this, I'm
going to use a homemade tool.
I got this from Sheldon Brown's website.
You can buy these parts just at your local hardware store.
It's a two-inch
long 5/8-inch bolt. I have a half a dozen
lock washers, a flat washer
and a nut for this bolt. So what I am gonna do
is slide this bolt with the lock washers in through the back.
Put the flat washer on.
And then put the nut on and then screw that down.
And then
to get this tightened down I have a 15/16th
inch socket with little extension on a 1/2 inch drive ratchet wrench.
And I am gonna use that to hold the bolt in the back.
And then I have a big Crescent wrench.
So I am gonna use this to tighten down this
nut onto here.
What's gonna to happen is, as this gets tightened down
and it's going to clamp down on the fixed cup,
eventually as I'm turning this,
this pressure is gonna go ahead and loosen
this fixed cup. Cuz this is the right side and it's
left hand thread. So to loosen it
you turn it clockwise. So go ahead...
And eventually
you might want to get a cheater bar. So I've got my cheater bar here.
If I had two half inch ratchet wrenches, I could use
one on this side too. But I only have the one.
And I think it's broken loose. Yeah.
Use this to remove it.
And there it is. Now all I have to do is remove the bolt.
And so there, that's how you remove
a stubborn fixed cup from a bottom bracket.
I hope that helps!
