Fused Ceramic 6 Puck to flywheel?
 

Was out driving today and went to do a hard launch and instead of the tires letting go the clutch took all the slippage and welded itself to the flywheel. Atleast thats the only thing that makes sense. The clutch will not disengage no matter what I try. I was under the impression that a Ceramic 6 puck clutch could take the launching abuse?

Has anyone ever welded their clutch to the flywheel? Any way to get it unstuck? I have tried locking up the tires from ~7000rpm with no luck. I am really hoping I do not have to pull the trans but if I do I do I guess.

Tried doing some google searches on it and it seems like a pretty rare occurrence to melt a ceramic to the flywheel.

So you Turbo'd guys be careful, I just assumed id slip the clutch but she is stuck good! I read that sometimes if you jack up the rear tires and throw it into a high gear and drop the jack it can be enough of a jolt to free the clutch. Going to go out to a parking lot tomorrow and give that a try. I also read that if you can get it unstuck that usually you are good to go as it will reseat itself. Any truth to this?

Thanks guys.

Wow...... Sorry

so just to be sure it wasn't just an actuator failure, if you put the shifter in gear and push the clutch pedal down it will not start right?

Worth investigating. It sounds like it could be a clutch hydraulics problem. The CSC is prone to failure.

The clutch pedal feels normal, which is weird. The car will start both in and out of gear. But when it starts in gear it doesnt matter if I push the clutch in or not the car will move forward and start.

I have tried to use the starter to break loose the clutch by throwing it in 4th gear and then cranking over the engine, but it just held the starter. I have also tried going out in 2nd gear and slamming on the brakes with the clutch pressed in to try and free it with no luck. It just stalls the engine.

I am going to give Zspeed a call and see if Joe has any suggestions on what is going on.

If it doesn't work, I do have the clutch you will want to have ;)

Im listening, lol.

to melt ceramic you would need some intense temps!

Wow that's odd. I had the ZSpeed daily disk that fused itself to the flywheel from a dig at the track, and was sent the 8 puck clutch disk a week later. So far I haven't had any sticky issues, but it makes quite a bit of swirling noise whenever I'm going in reverse on a slope.

Yeah I spoke with Joe at Z speed and he thinks the probability of getting it unstuck is next to none. Going to go out and try this morning after it had time to cool, maybe it cooling down was enough to allow me to separate.

If your gonna break it, break it good right? argh

Joe said he has never heard of a ceramic melting to the flywheel. I guess I am just that lucky.

Check the master cylinder and csc first. Seems more likely than melting a clutch?

Wow Mitch.... sounds like you need to unbolt that Twin Scroll right away and sell it to me for dirt cheap! :stirthepot: Obviously you just can't resist torturing that poor 40th! lol

Good point. When mine fused, my car would die while it was in gear. Plus, I couldn't get it in gear without shutting down first. My tech had to use a mallet and screwdriver to separate the clutch from the flywheel.

Get the car on a lift, grab a flashlight, and peek through the rubber dust cover while having someone step on the clutch pedal to see if the CSC moves. If it doesn't move, then maybe the master cylinder failed.

My car will die when i'm in gear. If it was the CSC failing I would have no clutch. I have the complete opposite, the clutch will not disengage.

Also I found out today that the car will not let you brake boost the car. As soon as you press the brakes and try and get on the gas it will cut all the fuel to the car. I was going to try loading up the clutch and essentially press all three pedals at the same time to break the clutch free, but the car would not let that happen.

Mark - Just goes to show what these cars can take. They're are awesome cars.
