Ferrari Mailing List: Re: 512 TR no drive

[TheMightyToe (themightytoe]

Well,

Fun to speculate, but my 2nd M3 threw a clutch cetrifugal spring through 
its bell housing at about 44k miles (fortunately it threw it down at the 
road!)...  punched a dime sized hole in the bell housing too.

My 348 had its throwout bearing replaced (twice since the first time it 
was leaking, 2nd was a freebie) and after learning how to heel and toe 
at MSR's braking zones in it, the clutch was pretty well toasted 
(throwout plate teeth broken in several places but still barely attached 
to the main plate) at 25k miles (my bad)...   Fun challenge driving the 
thing 90 miles home without stopping to avoid the drive train halting 
(since it would not disengage the clutch the entire way!)...  rev 
matching on downshifts was much easier than upshifts...

Good luck and hopefully it won't break the Xmas budget too badly!

Mike
