The 9000 does not have a pilot bearing like the old 900/99's, the throw-out was swapped with a newer one, and the slave cyl. rebuilt by me. If this was the problem, I would expect a lot of noise with the pedal fully pressed, but the noise is kind of proportional to the torque conveyed to the transmission. That means the source of the sound is where the pressure is applied. > >> Sounds like a pig dying or somethimg, metal-to-metal. > > Ouch.

Lots of work, I'm afraid. > I can think of only three possible explanations, listed in order of probability: 1. The disk is doing some high-frequency judder, causing the spring action to produce the metallic stream 2. Problem with the disk itself, but its a genuine Sachs 3. Disk wrong way -- Frode
