[QUOTE="Terrorist 5.0, post: 1560058, member: 30689"] So today I took the transmission and bellhousing out of the car today and took some photos along the way, along with what I found. I am still planning to take the measurements that weendoggy (lmao) mentioned earlier, although the flywheel measurements are going to be difficult without taking it back out. I may email LMR since I bought their flywheel (SVE), and ask them to measure it. In the pictures shown, the clutch fork position with my 8lb preload dialed in, the position with no preload (just the fork up against the fingers), and whatever I found in the bellhousing. Keep in mind, all these components are brand new, and have only been in use for about a month and a half. I cleaned off all the parts with brake clean prior to taking the photos for better clarity. Before I took the transmission out, I looked at how the clutch fork sits. It seems to be ever so slightly biased to the rear. So, beginning with the my main suspicion, the pivot stud (lengthwise), the head of the ball is pretty shiny in some spots, and is beginning to have a notable flat spot. It had a lock washer under it, as mentioned before. I feel that with how long it has been used, it shouldn't look like this, although I didn't use much grease on it. The fork already had some on it. The clutch fork shows some signs of wear in the form of shiny spots on where the throw out bearing rides. This doesn't look out of the ordinary to me, unlike the pivot ball. The throw out bearing itself still turns very smoothly, and doesn't make a noise. The bearing retainer really caught my attention. There is a shiny spot where the throw out bearing rides, and is beginning to make a slight ridge which I can feel. It is the same all the way around. I attribute this to the hollow sound when the clutch is used at higher RPM. All the pressure plate fingers appear to be sitting evenly. The reason I posted this is because I cannot tell exactly what to do with what I saw. My current gameplan is new components all around. They are cheap and good insurance. As for what is causing this, I do not know. Can anybody provide any input on this? I will be taking measurements soon, and comparing them to my old setup. Happy holidays.
