Reply With Quotegot picks of the rest of it?
my mates clutch did this in his civic....turns out it may have not been a genuine Exedy (wasnt stamped) but other than that the friction material just fell off.....
what would cause this? clutch
exedy stock replacement about a year old (30000kms or less)
showed no signs of slipping before it spat the dummy.
I have been told its due to the pressure plate mulfunctioning, meaning i need a whole clutch kit.
what are your thoughts?
cheers

Re: what would cause this? clutch
its not a fault of the clutch. what you have there is a misalignment of the input into the back of the crank ie its on an angle.
this causes flexing as the clutch spins which the workhrdens the material and snaps the disc.
it can be caused by numerous things ie:
flywheel not faced correctly
engine plate bent or missing
gbox not aligned on the dowels correctly
and a few other things but the above are the biggest contributors.
no a clutch supplier wont give you a refund because this is not a normal failure.

flywheel was machined correctly, gearbox was on properly. Clutch supplier (different company) said exedy clutches are rubbish and likely to be fault of pressure plate.
as for the rest of it, i dont know haha, there were only a few shards left in the bellhousing. I presume the rest is on the road somewhere.
Re: what would cause this? clutch
ive used alot of exedy clutches and never had a problem.
i have seen this on numerous occasions where a customer has changed the clutch himself and bought it down to me because "it wont select gears properly" .only to hear a crunching noise and after removal of the gbox ive seen this.

Re: what would cause this? clutch
true
Ive done many a clutch in my day, this is the first to fail.
there was no sign of slipping or anything, just a sudden failure.
Re: what would cause this? clutch
put it on ebay, sure some noob will buy it
Re: what would cause this? clutch
i vote misalignment as well.. if you are reverse loading the material on every revolution.. (perfect cyclic reverse bending test) and it is because of input shaft vs flywheel misalignment.. it should all break at once....
maybe there was something that caused the gearbox to not sit on dowels properly or? evan a mm out could cause it...

Re: what would cause this? clutch
the gearbox was properly bolted up, i doubt it was that.
Re: what would cause this? clutch
wonder what it was then?
if the flywhel and gearbox were "true", then the pressureplate couldn't do anything else but hold the friction plate flat on the true flywheel.... if it was slipping severely on one side, it could have failed first....
are there heat indications on any particular piece of shrapnel to indicate it failed first?
is still a fairly impressive failureand could have been manufacturing farkup.. but rare.

Re: what would cause this? clutch
nah, if you look near the rivets that hold the outer plate on you can see that they have been worked to the point where it snapped.wonder what it was then?
still a fairly impressive failure
seen it on a few occasions, and yes even 1mm off on either side of the box can cause this over time, speaking of which how long had the clutch been in there?

Re: what would cause this? clutch
hmmm, back to school for me to learn how to read.
if its out by only a slight amount it would probly take that long to snap completely but it depends on how its driven.

a couple of big metal shavings looked fine, clean etc. like a sudden failure.wonder what it was then?

wouldnt i have noticed if the clutch was slipping?
