I just had to pull my tranny because it was making an awful chattering sound. I thought it could possibly be my throw-out bearing because I just replaced the clutch 10k ago. Well I pulled it off today and the TOB was fine so I pulled the clutch. One spring on the disc is about to fall out and the others are loose enough to be worried about. What the hell? Guess all the horror stories about the ACT disc's and their springs are true. Guess I will try Centerforce. I cant be replacing a "Heavy Duty" clutch every 10 thousand miles. :thumbdown

I do not know what to say, other than I LOVE street discs... It could be a fluke or a bad batch of discs. In ether case, I would send it to ACT to see what they will say.

Also, you can not measure clutch use strictly by miles. How was it used in those 10k miles?

my ACT is a POS compared to my old Centerforce 2500. Im goin back to CF when this ones finally done in a few k :thumbdown

My ACT 2600 in my Talon has never given me a problem tho, weird

Upon doing some research and searching for similar problems on this site I have found out that there are a TON of people who have had this problem with ACT. Weird how I had never heard of it before. I thought ACT were the top of the line clutches for DSM's but now I am beginning to think differently. The warranty on the clutches is only 90 days from purchase which I am far past. To answer the question of how it was driven I would say not hard enough to wear out even a stock clutch at 10k. I probably didnt do more than 5 launches in those 10k and even gave it 1k to break in as I had just finished rebuilding the motor when i did the clutch. I have also heard that there is some kind of recall on this issue? IF anyone has any info about that please let me know. I am planning on contacting ACT either way just to see if they will do anything.

Wow. 2 months and my street disk chipped, lodged in between my disc and flywheel, and made my car creep like an automatic wouldnt disengage to shift gears...blah blah. I'm back on my centerfoce now. This happened, eh, 5 days ago?

I Love my ACT clutch and have had like 3 of them now. Never any problems ever. I only run the 2100 with the Modified Street disc. Not sure how it's modified but have never had problems to date.

I think some of the problems that many of us have is because were WAY over the torque rating for the clutch...

So what should I get a 6 puck? Doesnt make sense though...the disc looks brand new, no scars or hardly any wear, just the springs. I mean hell the stock clutch held up to more abuse than this thing.

My Eclipse had a CF DF clutch when I bought it. It was nice, but I don't think I drove more than 1000 miles before switching to the ACT 2600. I haven't had any problems with my ACT.
I bought a CF stage 2 clutch for my old '94 Mirage 1.5L. I had just finished the break in period when this happened...


I never beat on this thing, and the wierdest part is that it happened during a cruising-in-neutral to 4th gear change. CF wouldn't give me a new one or anything.

Click to expand...

when you say chattering sound, was it louder at idle? on and off?

you sure that chattering sound wasn't something inside the trans? I'm on my 3rd act 2600 and no problems. I got a chatterning sound as well but it was definitly my trans.

It all started when I put the ACT clutch in. It was really hard to shift 1-2 sometimes but I just delt with it. About a month ago it started making a squeeling sound only at idle when the clutch was depressed. If I pressed the clutch in the noise would stop. Well on Friday it finally got out of hand. I started the car and backed it out of the garage. It made a really loud chattering sound when I barely let the clutch out to back up. I stopped, put it in neutral and let the clutch out and heard the same chattering/squeeling sound. Put the clutch in and all noise went away. I started driving it around and noticed that I only heard the noise when I would barely let the clutch out in first gear going from a stop and every once in awhile when I would shift as I would let the clutch out. It was loud and embarassing as hell so I went home and pulled the trans.

between DSM Tuners and DSM Etc. I have found AT LEAST 20 cases where this same thing happened. In my case. I lost the clutch and the also new Fidanza Flywheel. Both items had a little over 3 months and less then 3000 miles on them. Both items are totally destroyed. Total loss, $640.

Clutch with no spring.


Flywheel

Deam i had problems with ACT street disk too. Maybee two weeks after i bought the car it wouldn't disengage out of gear. So i pull the tranny off and find that center piece of disk is all toren up. All the springs chewed up, but the friction material was like brand new. So i wanted to try different and i buy exceddy street disk. I put that on with act 2600lb plate and i have been driving the car for over 3 months now and no problems whats' so ever. No clutch chatter or any of that BS. I been launching the car, and it holds like charm, no slips so i dont know how long it's going to last like this but its working for me.

Have all, or most of the fokes with the street disk seen this happen over time? What is a way that we can correct this and straighen it up with ACT?

Hmmm...interesting.

I run a Shep tranny, ACT street flywheel, ACT 2600. It is just now starting to slip, but it has seen over 50 7000rpm launches; we're talking hardcore launches, no grandma driving. I like it so much I ordered the 2900 to take more torque with my new engine.

ACT rocks

My ACT street disc blew up too.

I am now running a clutchnet 6-puck. It's not perfect either, but it's no worse than a damned exploding disc that also killed the synchros in my transmission.

I'm not very happy with the ACT dics as of late.

It definitely sounds like ACT had a problem with some bad springs on their street discs. But you need to keep something in mind, 80-90% of DSMs out there are using ACT clutches. That means that they are going to have a HUGE number of complaints. If even 5% of them go bad, that would constitute 100% of CF or CM users. So you can’t go by what you hear on the boards, because for every complaint about ACT clutch, there are 20+ people who didn’t post that their ACT clutch is doing fine.

You guys should have seen how many complaints people used to make against CF, when it was pretty much the only clutch we could use! At least ACT would stand by their product (in most cases), you couldn’t get CF to even look at the clutch.

ACT may have a huge DSM following, but so does other companies making other products. For example, you don't hear about my FP Turbo went to sh*t, or my AEM EMS reset to default settings, my Greddy IC kit busted a seal, etc.

I'm still waiting on a response from ACT. I emailed them, I'll give it until Wed, before I make a phone call.

>ACT may have a huge DSM following, but so does other companies making other products.

There are probably 30+ ACT clutches to every FP Turbo…. Besides, do you know what is the #1 turbo sold by most DSM vendors? EVO 16G, which is one DAMN good turbo!

>my AEM EMS reset to default settings,

Not a very good example… Glitches in early AEM code caused several people their motors…

>I'm still waiting on a response from ACT. I emailed them, I'll give it until Wed, before I make a phone call.

Hell, I’d call them NOW! (Edit: I see that you are in Germany, so it is probably not as easy to call...)

Looking at the other couple of picks in this tread I see you have all springs. I took off my pressure plate to check out the springs and everything is fine. The soild looking objects seem to be a rubber of some sort. Do you think would hold up better than the all spring disks? ACT classified mine as a "Performance Street disk".

Yeah I emailed ACT also and am waiting for a response. I highly doubt they will do anything but its worth a try I guess. So what do you guys think I should do? Should I go buy another ACT disc and PP and hope that it works or should I try something different like Centerforce or Clutchmasters etc. The only reason I went with ACT in the first place is because that seems to be the most popular clutch being run by the DSM crowd. I dont see to many people running the CF or other brands.

Turbo90gsx: How long ago did you purchase that disc? Maybe act changed the design? I have never seen a disc with rubber instead of springs.

Both rubber bushings and metal springs are springs, the difference is that rubber possesses damping qualities, where as metal springs do not. I have also noticed that ACT went from OEM style metal/rubber spring design to an all metal spring design. I am not sure why they did that, but one thing is pretty clear, they seem to be having some problems with their current all metal spring design.

I've been running an ACT2600 for two and a half years with no issues... Must be a bad run.

I bought my kit from Slowboy Racing in early April I do believe.

Leon, ACT may be better than CF but that doesn't make this ok.

My clutchnet disc WILL NOT lose a spring, I can guarantee that. However, it too has other downsides.

When my ACT disc went, I walked to the guys at ACT. Their response made it seem to me like this kind of thing has never happened before, and they just blamed it on my installation. Now that I see how many people it has happened to, I'm a little less pleased with that response...
