clutch "throwout bearing"??

["Andy Webster" <trunkie@hotmail.com>]

hello list,
okay, so while my engine is out I thought I'd glace at the bellhousing 
contents.
There is a circular component over the input shaft and attachd to the 
lever/fork from the slave cylinder. Is this the throwout bearing? I ask 
because mine does not spin. Should it spin? It looks like a thrust 
bearing...
I never heard any bad noises or felt any problems that obviously arose from 
there.
It looks tricky to remove.
