That interface doesn't look like your problem to me.

   At the end of the Panteras Northwest Fall Cruise last September, my
   clutch was becoming stiffer by the day and at the end, It was all I
   could do to get home.


   I pulled the engine and ZF yesterday in prep for a restoration on the
   car and when we pulled the two apart to diagnose the stiff clutch, I
   found that the fingers on the clutch lever arm and the `ears' on the
   throw-out bearing were both extremely worn (see attached photos).
   Also, while the face of the throw-out does not appear overly worn, the
   bearing itself is quite loose and rattily.  The lever arm shaft moves
   freely enough so I suspect my problem was with the lever arm to
   throw-out friction.


   I'm likely going to have to separate the bell housing from the ZF and
   send out for repairs - I don't want to tackle this one myself.  I
   suspect the throw-out actuator will need to be replaced.  I put a very
   light lube on things when I put it together but no more/less than the
   last two times I've replaced this bearing (with a stock unit
   previously) and never seen this kind of wear.


   Stay tuned.  I sent these pics to Adam at Pantera Performance and we'll
   see what he has to say.  I was running one of Quella's throw-out
   bearings as well.  Glad I won't be driving it for a while.


   Mike
