The Lemons Civic ate a clutch at a time trial last year. Today was the day to replace it. The team had mentioned I end up doing most of the work on the car so today I stepped back and let them take over. The ladies did most of the work.
I don't think I've seen a disk fail quite like this. It's even a quality Exedy disk instead of the usual junk. It does have 8 Lemons races on it as well as a Time Trial event and a bunch of Rallycross runs.
That's a tiny ass clutch.
Check the alignment of the engine to the trans. That type failure looks as if the input shaft and the crank shaft are not perfectly parallel. Slight angularity causes fractures of that sort even in a gently driven car.
I've done that. I blame it on aggressive downshifts, but that is a wild guess. I do know it's a bad habit of mine.
That is impressive, and the clutch also !
I have only seen that kind of failure twice, and both times it was because the transmission had a hosed bearing on its input shaft.
Not sure how this translates to a transverse app with its super long shafts, but one of those failures was a Subaru, so maybe.
In reply to Appleseed :
It's a tiny ass engine.
I pulled a clutch out of my Dodge Ram that was heading that direction. A foreign object (from the dual mass flywheel) got into the bellhousing and had cut through two of the webs connecting the center of the disc to the friction surface. This is the end game of that particular failure process.
