Sorry, I must be remembering wrongly - thought you had the atr clutch fitted

Yeah it's possible I suppose, but there are limiting factors on the movement, beyond the pedal anyway - e.g. total travel length of the slave cylinder, total deflection on the release finger springs etc.

Be interesting to see what you find. The competition clutch guy on here seems to be interested and helpful, so worth dropping him a note once you've had it apart and know what the issue is?

I bought my clutch kit from Htune. The Competition Clutch guy has basically said that anyone buying though Htune or the like are not able to have any warranty with them as the kit was not bought in the UK. This doesn't really bother me as I am swapping out the bearing with a Honda one anyway. We checked the OEM bearing with the Competition Clutch one when I fitted it. It was visually the same.

To my 5th gen I do. An ATR clutch would be shredded by my 4th gen

Oem bearings anyday. A lot if yanks have used aftermarket bearings and most fail. Oem seems to hold well.

^^That is what I am thinking now.

Can't understand a pattern part release bearing being of such low quality generally, that it would fail this quickly though?
If it has done, it just be expecting it to be a one-off

Did you take any pics of said bearing before you fitted it, merlin?

That sucks Merlin, all that labour for that one little part.

Does seem weird to have prematurely failed, must be something up? Last thing you want is to change it and then an OEM Honda one goes in another 800 miles.

Anyone know what brand the Honda OEM one is? I have a Naachi bearing for my gearbox/clutch change which I'm doing very soon. Is it worth me getting another???

Yeah I know, 12 hours (on the driveway) or so of work for a £38 part

At least Honda can get it to me by tomorrow morning.

Lings says that the Honda one is a FUJIKOSHI, which is Nachi.

I have yet to search the net for examples of the Competition Clutch release bearing failing.

My mate has a c4 powered eg civic. He had a new Exedy stage 2 clutch kit fitted. The release bearing failed after 500 miles. So we put a Honda oem bearing in and has done about 2k now. And still sweet. I personally wouldn't use a non Honda bearing.

Really? Sweet. Thanks for checking that.

Its weird though, I got that bearing in the XTD Stage 4 clutch kit. They're supposed to be on the 'cheaper' side of things but come with an OEM bearing.

Good luck with it again bud, not a fun job on the floor (I'm yet to do actually until a few weeks time).

Scion owners club seem to have had a few problems with CC release bearings and pressure plates.
It seems for the clutches on those at least, there may be some different versions of pressure plates out there.
That's what I seem to be taking from the threads I've read, but that of course doesn't mean it's fact.
That may be why CC aren't happy with the stuff h-tune have been selling (might be new old stock that they've changed the design on now due to problems with the original design and shouldn't still be out there maybe?)? I dunno, that's also hypothesising so don't take it as read!

I reckon you should take the cover plate off and inspect the pressure plate when you take the gearbox off anyway, to be sure. Could be the pressure plate springs making a bid for freedom and starting to rub on the inside of the cover plate fingers?
