I can see wear on the throw out rod...... $15, I'd replace it and apply grease to the surface that contacts the actuating lever. It will keep eating the head of that rod.
The mechanical advantage from moving the hand control full throw (30*? Working range, 5-15*?) to the point where the actuator pulls that rod 'out' by less than 90* rotation is pretty significant. I expect the force must be similar to a claw hammer prying a nail out of a board. All concentrated onto the sharp lip of the actuator that first makes contact.
I believe the bearing the other end of the rod rides on is not decoupling the rotation of the pressure plate adequately. The actuator mills off the back of the head as a result. I know the part number of that bearing has changed at least once. I don't see any mention of lubing that bearing in my shop manual, either. Grease near the frictions probably a bad idea.
I don't like the look of that steel, either....
