Thanks for this great post Rick!

I've got a 78 car that I did a clutch on 200km or 6 years ago. The car has a mild clutch vibration when engaging the clutch gently at lower RPM. A more aggressive clutch engagement doesn't show the same symptom.

Its been so long since I did the clutch I can't recall if the bearing was also done. The "Porsche specialist" hack who put it in for me cross threaded the retaining bolts for the bearing and one bolt was only half inserted! Pulled it all apart myself after 50k of driving, found the mess and corrected the retaining bolts. It probably damaged the bearing now that I read your experience. I think I'll replace that bearing again and write back on my results.

Thanks!
