Faulty clutch/TOB issue

I just finished refreshing the CSX powertrain last weekend and finished my preignition checklist. OK we are ready to go. Let's verify clutch operation. Worked as expected but engagement point was a bit lower than expected so I had a look at the cable end at the 555, looked OK. When back in the car I pushed the clutch again and CLUNK......WTF. Now the pedal has no spring to 50% and is impossible to push any further. The pressure plate can no longer be disengaged. I am guessing the throwout bearing has slipped off the fork. Looks like the 555 will need to be dropped to repair.
Any ideas what I could have done wrong other than I picked the wrong hobby LOL?

check the clutch cable where it rides in the grouve coming over the top of the peddle assembly

possibly it wasn't completely seated in the grouve (?) when attached to the trans at the other end

also, my understanding is that 523/568 cables are slightly longer than 520/555 cables so if one snuck in there .. things won't be right

Thanks Johny, I did double check the cable at the pedal but won't hurt to check again. The shift cables were fine with the 555 last year

the TM gods have answered my plea..I removed the MTX Clutch arm grommet, checked cable position and operation. Everything looked fine so I reassembled. The clutch works fine now...I now wish I knew what the issue was..

ya know... ^That^ sounds familiar...too much so

so I'll stick with cable not fully in groove and prevented from moving off some stick point on the side of the peddle bellcrank that until you removed the retainer at the clutch arm..cable tension .. couldn't seat properly..
yeah sounds really really ..really... familiar

that or maybe the inside end of the cable wasn't seated properly in the adjuster block..?

Thanks for the note

I'll go with the cable was not seated in that groove also. Been there, had that happen once or twice.

To add to the notes, there should be a curved metal retainer clip that snaps over the top of the positioner pawl thingy to keep the cable seated down in the groove. It is not necessary for function, I imagine it was more of an assembly line aide to keep the cable seated while things were being built up. Most cars by now it is probably long rusted away, fallen off or tossed aside during a cable replacement.

My CSX has this but not in the Sundance (I purchased new in 87)
