Bill,
That clutch riding over time was likely the cause. The hydraulic clutch
makes it so easy to hold the clutch on the floor in traffic that folks
forget what they should've learned as beginning drivers. Interestingly the
thrust bearing in this engine was well worn, but intact. All the wear was
on the rear thrust surface of the crank. For racers running heavier than
stock pressure plates with these hydraulic slave cylinders it's something to
keep an eye on.
