Clutch Chatter?

[bidicamaro]

First time I've ever had clutch chatter while it was enguaged but goes away at the press of the pedal? What gives? 94Z28 with the 6 gearbox... No slippage that I can notice. Just an anoying chatter while out of gear idleing?

what clutch? how old is it? what flywheel? has it been resurfaced?

a clutch shouldnt chatter unless it's a spec 3 equivalent or greater and even then it is not common on a spec 3

mine does the same thing.. its been doing that for years
i figured it was normal:confused:

Something just isn't right. Like mentioned a clutch should only chatter if it is a very agressive material with a stiffly sprung hub, or an unsprung hub. I can't even begin to think about what it could be. Maybe a twisted input shaft?? Allowing the disk to vibrate on it...

I have no idea what the clutch assym. is. It's got whatever was put in it before I got it. I've never driven a 100% stock Camaro so I'm not sure what they feel like. I know the SOB grabs (at least it sure feels like it does). I guess I'll crawl up under and take a look at everything I can see. Anything to look out for on the outside? I'm not digging into this car right now because I don't have the time. I'm out of VA on Dec 9th and between now and then I have to get my wife moved to WA and the Navy to ship my crap. Any advice at all is sweet...

I also have a 94 and mine does the exact same thing. I have a spec stage 3 clutch. One of my buddies said that noise was normal. He also said that is was the throwout bearing and it was the way that it is hooked to the presssure plate. I've never had a t56 out so im not sure. Thats just what i heard.

My ears have felt them same tunes as well... Guess I wont worry about it until it shoots threw my floorboard or I get it back to either TX or WA (depending on where the money is) and get to building... SWEET DEAL PEOPLE!

I have a spec stage 4 and there is no noise. Sounds to me like your throw-out bearing.

I am 100% convinced that the majority of clutch chatter seen is due to installation. Personally, I feel it's going to be in how the pressure plate was torqued down, and whether or not everything was all torqued down the same. If you have slack in one side I could see it causing the chatter. FWIW I've had a Spec II, McLeod Single and McLeod Twin, and a Tex OZ700. The Spec II I did myself and though it was known for chatter I took my time and was very meticulous and I got zero chatter out of it.

Now something like a Kevlar Textralia or a Spec IV or V, I can see chattering without any cause. But most of the clutches we normal guys run shouldn't have any chatter.

+1, the big boys chatter but this should not. It has to be the install, as some will and some wont. Even then, some of the big boys DONT chatter.... So this has to be an install issue.

I agree. Factory clutches seem to have chatter problems, but I've had zero chatter with my old RAM HDX and my brand new RAM Powergrip (both installed by me).

typically it'll require inspection which means you need to drop the transmission. Honestly, I'd rev it up and slip the clutch out and try to wear the surface down a bit and see if that help.

I'll throw in my imput on this, i will say this, A stock type clutch should not chatter AT ALL, if it does, something is messed up, & from what i found on my car, i think the main culprit was the "pilot bearing", when i tore into mine to replace the clutch, i found the inner bearing was totally desinagrated, it was letting the imput shaft wobble around, i could even feel a slight vibration at around 2K in "N" with the clutch peddle released, some of the chatter may have been caused from the PP or flywheel (hot spots & distorsion), I was alittle surprized when i found the pilot bearing like that, but i can see how it would happen & was sure it was causeing some problems, but didn't realize how much it was causeing untill i got it back running, i'm sure this is a common problem on are cars once the mileage racks up, pilot bushings will wear slower & being a solid piece, theres nothing in the middle to come apart. In the end, i went with a Centerforce organic disc, re-man flywheel & a LT4 F1 Racing PP (mix-matched stuff), you wouldn't beleive how smooth this clutch is, it feels like a brand new car, the ingaugement is like silk, i had so much shit going on with vibrations, chattering, you name it, heck, even the rearend doesn't bang or jerk around on slow turns like it did (it has a spool). I wasn't exspecting the car to react as nice as it does being i mixed parts, but it works great, so if your in there, replace that pilot bearing, no matter how old/new it may be.

I just re-read the OP's post, and I caught the end where he said "just an annoying chatter while out of gear idling."

Throwout bearing. Common problem. Live with it, or drop tranny to replace. It's not chatter he's hearing, it's the throwout bearing rattling around. Press the pedal, puts pressure on the bearing, rattle goes away.

yea i didn't even see that part... def. not chatter. It happens with alot of cars with either worn throwout bearings or aftermarket ones. Mine does it sometimes, but not that loud but I don't hear it anymore anyways because of the exhaust
