Hi,

I am replacing the bottom bracket on my spinner. The bottom bracket makes a clicking noise when you spin on it. I figured it was about as good of a time as any to replace it. I was able to pull off the crank arms without too much trouble but the bottom bracket is a little tougher to get out.

The spinner is about 10+ years old.

It is a square taper bottom bracket with no splines for removal. There is what looks like a small gasket so I was able to pry that off and I see loose ball bearing with grease. There is a round metal thing enclosing the ball bearing so that they don't fall out.

A couple of quick questions:

1) How do I remove this entire bottom bracket (housing, etc.)?

2) Is it fairly straightforward to replace this with a more updated square bracket enclosed type of bottom bracket?
