Here's what I think I saw on your first repair. Kind of looks like the TO bearing might have walked off the finger.

Maybe it's the camera angle or the lighting (or my eyes), but something doesn't look right with that finger.

In any case, hope you've found the problem. Too bad you'll have to split it again, but this should last a while.

You're comparing 2 different pressure plates.
One from 2 years ago and one from now.
There is no possible way for the fingers to "walk off" the throw-out bearing on that that pressure plate, at least not if they are still attached.
You should change your monitor, with a 40" monitor everything looks as it should! ;)

Yeah, I knew it was 2 different pressure plates. Maybe I was just trying to see something. Just hope torch has found his problem.

Well I ran that by the wife, mainly because I'm getting older and the eye sight isn't what it used to be but it's still good enough to be able to tell by the look I got it's not gonna happen. :(

Thanks. I see what you mean in the pictures, however they look much better in person. I think it is an effect of the lighting on the dust vs polished contact area. The pictures were taken on disassembly, without any cleanup.

I replaced the pressure plate assembly last time primarily because of all the dings from broken bits of spring bouncing around in there:



I was concerned that there could be hidden cracks or fatigue that could lead to catastrophic failure if it was re-used. This time the springs were intact and there was no visible damage to the pressure plate assembly so I just replaced the friction plate. (And the gasket. $70 for a gasket. Ouch.)
