throw out bearing issue with luk pressure plate. any suggestions?

I'm getting ready to put the engine back in my truck and I have a new ford t/o bearing to put in. I was having issues with a slight grinding noise prior to the removal of the engine, but the grinding only occured when the clutch pedal was not pushed in. The noise would go away as soon as you pushed slightly on the clutch pedal.

I went to put the new T/O bearing on the transmission and I observed the center plastic section of the bearing had rub marks and was coming apart. It appears the fingers on the pressure plate are a bit too long and are rubbing on that part of the bearing. I put the new throw out bearing up to the pressure plate and observed the plastic section of the bearing on the face of it will rub on the fingers also.

Is this normal on this set up? It's been a year or so since I have worked on cars but I don't remember any throw out bearings being set up like this.

Thanks
Mike

pics? i believe mine was the same way when i had my trans out, but will need to see pics to confirm. the grinding noise is most likely the rollover noise that is common in these trucks after a SMF swap

will post pics soon, but it looks like the noise is coming from the pressure plate chewing up the throw out bearing.

So.. Is that plastic center piece supposed to be damaged by the pressure plate? I sorta wish I had a factory pressure plate to compare and see how it's set up. I have the new throw out bearing and am sort of sad that the same thing will happen to it should I put it in.

I've looked around on line and it seems there are quite a few people that have issues with the throw out bearings making noise and exploding on these.
