Thanks for the info in this thread - very helpful... Did mine this weekend with the expert assistance of @
Joesurf79. Thanks Joe!
Old TOB was shot, but I caught it before it did a lot of damage. Puddle in the bell housing where it had lost all of it's grease. Little bit of play in the bearing, but it sounded dry and rough :
35k miles on the clutch and ~20 track weekends. 18k of those were by the first owner, so I didn't really know what to expect. Turns out things looked good. Old disk had 1.7mm of material left before the rivets. New one had 2.0mm. Service manual says to replace if it's below 0.3mm.
Pressure plate fingers were a little worn, but otherwise looked OK :
Replaced the disk, pressure plate, fork, fork pivot, and the TOB. Used the old flywheel. Nice quiet clutch again. Given the wear I should be able to go 150,000 miles on this clutch... or 35,000 until the TOB fails again...
