clutch operation help, sproing then cable is somewhat slack Options

[mskala]

Maybe somebody can educate me on how the clutch is supposed
to be. While driving today, I felt something give when I pressed
the clutch pedal, then it was still pulling (cable not broken) but
didn't have the pedal travel to release all the way.

Limp home, check back of cable, still fine not frayed. Check front
of cable, not frayed. Higher free play than it was. Looked at
front of tube while pressing pedal (tough to do!), tube not broken,
also firewall tube not broken.

When cable totally removed (looks good still), the release fork can
be moved about 1 inch without any resistance. Can't see enough
inside to tell anything. Should the release fork be movable (much)?
Do I have to pull the trans to find out what's wrong?

Thanks all.
