Thread: What happened here?

oh and its even on the same spot on both?

what was the problems that caused you to take the clutch out? what was it doin?

i had the same problem as you did too...i did my research about the clutch cable and everything that people suggested...i replaced everything that had to do with the tranny and clutch itself...since none solved the issue i decided to ordered oem clutch, pp, tb, etc...solved my problem and drives fine...

I would say there is air in the system or one of the cylinders is leaking/bad. I know that before I would be done bleeding the system it would act exactly like you describe.

what kind of break in period did you allow for the clutch?

There was obviously a high spot on something, either the flywheel, the disk, or the pressure plate. Was the pressure plate installed new or used?

Yep, that's what I'm thinking as well. Everything else are red herrings.

Other than faulty production, the high spots could have formed because clutch material was being transferred to the flywheel and pressure plate surfaces (similar to when brake pad material transfers to rotors) due to localized hot spots maybe caused by a clutch cable that was too tight (causes low engagement too) effectively reducing the clamping force of the pressure plate allowing the disc to spin somewhat freely during normal driving.

Edit: Oh I see you have a hydraulic clutch... Well, something happened to cause all that heat. Not enough clamping pressure under normal driving conditions or somehow the clutch wasn't fully disengaging between shifts. I'm not real good with hydraulic clutch systems as I've never dealt with on directly.

Thus causing the flywheel to heat up from all that friction in such a perfectly symmetrical pattern. The hot spot pattern that was created may be a result of the how the heat transfered across the metal alloy makeup of the flywheel surface itself. Then it transfered the heat through the disk to the surface of the pressure plate. The pressure plate and the flywheel are in fixed positions relative to eachother so it makes sense.

Next.

Oh by the way if pressure plate discs are anything like brake rotors, you can't just resurface that sucker. You need a new one. Same goes for the friction plate on the flywheel. Time for a new one of those too obviously.

I think thats a stock fly and it can be resurfaced.

Oh what the hell I didn't even notice.

Sure it can be, but it will just have the same problem over and over again for it's entire life no matter how straight the surface gets. It's ruined. That's assuming the flywheel friction surface material is similar to brake rotors, which I'm thinking they are.
