Greg,
I have read through much of the previous threads an am trying to take a Sherlock Holmes approach. Given all the things you've done and all the suggestions, I question the validity of your clutch plate wear test. I don't have any info on the new style clutches, because they are almost none existant here in Calif. I do have the little tool that slips into the slot on clutches from the 60s and 70s, and I had to look in the book each time to see if the notches should be showing or not to indicate a worn clutch because I couldn't remember. I used a factory manual, but Haynes and other after market books are notorious for getting things bass ackwards. Why don't you state your exact test procedure, and perhaps someone out here can attest that you are reading it right. Once you dissengage the clutch, it is out of the picture. In 30 years as a MB mechanic I have never seen a clutch try to apply itself slightly to cause slipping.
