Last Sat. night we smoked our clutch in our feature. It left 3 hot spots on the flywheel,(steel), that showed clear though on the backside. It also warped the pressure plate a little. We run a 10.5" stock setup,(no springs in the clutch). We're pretty sure it was because the front seal on the trans. was leaking grease onto the clutch. We got the flywheel resurfaced & it looks fine. My question is, can we just clean up the clutch to remove the grease,(we were told we could), or is there a chance that it has been permenately damaged by so much heat? I know we will have to replace the pressure plate. We are 5 points out of the point lead & don't want to take any chances. Thanks.
PS. the clutch slipped after we got spun out & tried to get going again, but seemed to start working again after about a lap & continued to work ok for the remainder of the race,(7 or 8 laps).

Are you referring to the disc, You can't clean the disc if it's made from fiber. If it's a metalic surface. Clean with denatured alcohol.

Yes, I was refering to the disk. I don't know what it's made of. All I know is that it is a full faced type, without the sprung hub,cost over $100.00 from a racing shop (6 races ago),& they use them in alot of hobby & street stocks. I just didn't know if that much heat could cause damage that might cause it to come apart.

most likely you have a fiber clutch, once they are soaked in oil or grease they are usually done! That much heat definately isn't good for it! If I were you and a new one was only $100, I wouldn't waste my time on the old disc I would replace it.
