This is still not clear to us.

Is the clutch pedal able to be moved at all or is it depressed/released with no change in clutch engagement?

Please describe the term "seized". This is usually reserved for bearings, but can be used in other context. I believe those of us above are looking at your description and believing that the outer race of the TO bearing is seized to the inner race via the rollers in the middle.

Your description is starting to make it sound like the bearing is either sticking on the input shaft and not sliding (which would cause a hard pedal if it is released, or no pedal if it is engaged.

The only other thing I can think of is that there is some sort of binding in the clutch fork/TO bearing assembly. Maybe it is on crooked? Maybe there is not enough lube where the bearing rides on the input shaft front housing? Maybe the spring is on wrong? Maybe the pivot point is binding? These are just all ideas. Heck, maybe the slave is sticky and for whatever reason it becomes irritated when wheeling.

Some more discription of what the pedal is doing would be super helpful.
