assuming you know absolutely nothing about what's involved, you have to remove and replace the transmission. the clutch plate is bolted to the flywheel, on the crank of your motor. the disk is obviously between the plate and the flywheel. if you're planning on doing it yourself, just know you'll need help getting the transmission back in- it's VERY hard by yourself, no matter how experienced you are. make sure you have an alignment tool before you start too- i don't know how many times i've been helping someone do sa clutch and they lost/forgot/didn't know about an alignment tool. i'd say the hardest part on a honda is getting out the cv axles, and that's not that hard. pretty straightforward.

if you have an extra couple hours and 35 bucks take the flywheel and get it machined, i know napa does it, not sure where else. better yet if you're going to replace your flywheel might as well do it now since you'll have the tranny out. oh yeah- buy gear oil too. that's another commonly forgotten item.
