I just got done ripping out my Spec 4 puck sprung hub. When I got into high boost in 2nd or higher gear (with foot completly off the clutch) It would chatter horribly. There was some hot spot's on the flywheel and PP, but the damn thing never held from day one.
What causes chatter? Is it because Spec sucks? Does the sprung hub cause it? The hot spots?
I dont want to have to deal with it again.
I'm about to order up a clutchnet.com 4 puck spung hub with a yellow pressure plate. Think it can hold 300ftlbs?

Re: Clutch Chatter...
 

I'd guess defective clutch. I've never heard of getting chatter any time other than engagement. My sprung 6-puck chatters like hell during engagement but one my foot is off the clutch pedal it holds great.

Re: Clutch Chatter...
 

if it didnt hold from day one first off, it doesnt sound like you broke the clutch in improperly...... that would cause major clutch slippage from glazing the flywheel and disc

Re: Clutch Chatter...
 

Lol, I installed my clutch and ripped on it right away hope its ok.. Same with the obx lsd

Re: Clutch Chatter...
 

I've heard from a few different sources that puck style dont need a break in, just organic and stock.
But I did run low boost for break in with this clutch, kept it to 12psi for awhile.

Re: Clutch Chatter...
 

no need for break in on a pucked clutch they bit from day one. as for it being a spec and sucking from day one your not the first to say that. I have a budy with a accord a20 motor put a spec 6puck in her before he went boost. thing slipped na and was shot with in 25 miles on boost. they suck majorly better off running stocker haha

Chatter is from a serious amount of grip, or in case of a stock clutch - a warped or glazed flywheel/PP. The sprung hub is only supposed to dampen severe shocks to keep from harming the transmission parts.

If I were you, I'd measure how much the pressure plate compresses when bolted up. The clutches I've done in most cars compress by almost the whole length of the bolts that hold it down. It is possible it doesn't have enough pressure on it because of that. The other thing to look for is *any* bit of oil. Thats an easy way to create a slipping clutch. Besides all that, the hotspots are from slipping. Looks like it was slipping quite a bit to me.

It could also be a shitty clutch manufacturer, as they do exist. Action/ACT FTW.

did you get the fly wheel machined?
my brake in consisted of me stalling the car 6 times pulling out of the shop :1

Re: Clutch Chatter...
 

This clutch did'nt have serious grip, 15psi is all it took to get it to slip (with foot off the clutch).

About half the bolt length or so. It seemed to me there was plenty of clamping.

The rear main did have some dribble running down, but the PP and disc was completly dry & clean.
Yes the clutch was slipping with high boost.

Maybe.

Yes, I allways get the flywheel resurfaced on install.

1st-3rd gear burnout + some slipping for some reason really messed my ACT 6 puck up just earlier tonight... Sounds a lot like your vid. It isnt disengaging fully either and its a real pain in the ass to shift. I'll tear it down tomorrow and see what happened

Re: Clutch Chatter...
 

ceramic clutch?

Re: Clutch Chatter...
 

Ah so something WAS indeed slipping... I limped it 15 miles on the freeway like this :8

holy ----, well if it was in a honda you only have to worry about the passengers legs

Re: Clutch Chatter...
 

lol shane that was my spec stage 5, it was a 3 puck unsprung (stock type pp), virtually undriveable and a pain in the ass all around. It didnt last long in low boost at all, maybe a couple days? That double diaphram clutchnet 6 puck sprung has a much heavier pedal than stock but it holds ANYTHING. Never Ever had a problem with the clutchnet, it outlasted 2 motors and burnouts/racing. AFAIK pucked clutches dont require much of a break in, as long as the flywheel surface is pretty decent and unglazed/non warped/not beat go to town. Organic and Kevlar (esp Kevlar) disks absolutely REQUIRE a break in period. Also, pucked clutches can be soaked in oil and it wont affect them nearly as much as an organic or kevlar, which will burn up quickly.

Re: Clutch Chatter...
 

Holy ----! I dont think I've ever heard of a PP breaking.

Well then I guess I cant blame my spec sucking because of a leaky rear main seal. (wonder if sythentic had any thing to do with that, was'nt a OEM seal)


I started my install last night with clutchnet PP & 4 puck disc. The disc springs are completely held in with the plate, so it's impossible for the spring to pop out. Thats kinda nice.
