First major Elise repair: Installed a clutch

My throwout bearing started to disintegrate on the way home 2 weeks ago. So I bought an ACT LE1-HDSS clutch kit, and started pulling things apart.

With the help of a friend I dropped the trans, popped in a new clutch, and realized that the job required new pressure plate bolts. I never knew they had to be replaced, so I ended up waiting again for some ARP bolts from Monkeywrench.

Everything went really well. The new clutch is slightly more grabby in first with an ever so slight increase in pedal effort. I expect it will change behavior a little after it's broken in.

I took a ton of photos and did a massive how to guide on changing the clutch. It's posted over on HowTune: Replacing the Clutch | HowTune.com

I'm almost positive it was the original clutch, it was an oem unit and I don't have any records of the former owners replacing it. Not bad for 99,976 miles

Why did you drain the oil out of the trans?

He probably drained it so when the half-shafts were pulled, it would not leak fluid all over the place.

Yes, I don't have direct experience of it puking gear oil, but assumed it would given that the axles are bathed in it inside the trans.

Thanks for the kind words. I still need to finish up adding in torque specs.

I just thought I'd follow up on the break in period. At the very beginning the clutch felt VERY grabby. I was getting quite a bit of chatter at very slow speeds where you have to slip the clutch a lot (like pulling into your driveway, or the pedestrian filled parking lot at work). It made quite a bit of noise and you could tell the engine was flapping around a bit.

It also HATED slipping when theres a significant difference in engine and trans rpm (like if you let clutch in, and the motor idles down, then you try to get it back into gear because the light changes - like you know... when you should rev match).

I'm happy to report it's characteristics are becoming much closer to stock after a few hundred miles. I almost feels less grabby, and it's quite a bit more forgiving at low speeds. had me worried for a bit, I really didn't want to take it back out so soon.

It's really convenient that you just made this how-to a month before I had to change my clutch.

THANK YOU SO MUCH!!!!!!!!!

I can't even explain how easy your guide made this for me. Took a few days to do it since I was just doing it after work but it really wasn't that hard. And I've never swapped a clutch before!

Woa wait what? you need new pressure plate bolts? I installed the ACT HD-SS pressure plate and street disc earlier this year, and just re-used the stock bolts with a little red threadlocker. Is that bad?

Normally all PP bolts are "stretch" bolts and they stretch as part of the torque process, right? Last clutch I did was a 911 turbo and I remember having to reorder a full set.

+1. You're "supposed to" replace the flywheel and pressure plate bolts with new ones. Either OEM or ARP (which are better and reusable).

I'm not sure if using the old bolts would really give you a problem though if they went back in fine.

I would totally recommend removing the clam to do this. Not that you have to, but you would be amazed at how much access you get. It is not very hard to remove the clam, it will add several hours of work though. But it is straight forward work.
