act2600 question. is this normal?

V8s_are_slow · Mar 8, 2004

to make a long story short, i took the tranny out to replace my throwout bearing cause it was making a noise (or at least i think it was the throwout bearing). anyway, when i had the tranny out i put the clutch alignment tool in the clutch and tried to spin it just for the heck of it. just felt the urge to do it. well, the thing moved. what the heck?!?!? moved like maybe a 1/4 inch. the clutch "disc" didn't move but the center piece did along with the springs. springs felt pretty loose so now i dunno if it was the throwout bearing, the springs, or what was making the noise. i dunno.

but felt a lil uncomfortable about it moving and so decided to take it off to get a closer look. the friction surface is fine and all but the center piece seems to move. kinda hard to explain without showing it to ya. but if you were to hold the disc by the friction surface, you could turn the middle portion a 1/4 inch, back and forth. is that suppose to happen? i can't remember noticing anything like that when i installed it back in october. yes it's pretty freakin new and only maybe 3 hard launches during that time. should i replace the disc? anyway, thanks for any info.

It's not supposed to move freely like that. I'd replace the disc for sure. While you're in there put in a new TO bearing just to be sure, and closely examine the pressure plate and flywheel.

Very true what he said. Those cushion springs have a habit of popping out sometimes so a new clutch disc is in order as well as a new plastic sleeved TOB.

k well i just replaced the throwout bearing yesterday. thought that was my culprit. but what in the heck would make the disc go bad? it's almost brand new and it hasn't even been driven hard. flywheel and pressure plate looks just fine too. also, the springs looked worn on the sides, but dunno what could've done it. :dunno:

another thing. when i press in the clutch now, it's making a VERY VERY loud metal clanking sound. if it's in neutral it doesn't do it. was thinking that maybe it could be the dust cover for the tranny but that's on the back side of the flywheel. about to maybe just order a new clutch disc and fidanza flywheel come next monday. but is there anything else that could be causing a problem? i know when i put in the clutch i had to adjust the pedal all the way out. only a few threads are screwed into the pedal.

So you mean the thing in your clutch that was already broken just got worse?
Hmm I didn't see that coming.

well it was making a noise before i took the tranny out. figured it was the throwout bearing. it also had gotten to the point to where i couldn't shift gears. so my mission was to replace it but was unsure at the time of the cause for the shifting problem (slave and master cylinder looking okay). that's when i noticed the problem with the clutch disc as well. went ahead and replaced the throwout bearing and now it goes into gear. dunno if that (throwout bearing) was the actual cause or not though. hmmm.....

but anyway, now it's a loud clanking noise. i wouldn't think the clutch disc itself would make the noise but i dunno what else could be making it. the pressure plate looks alright. flywheel looks okay. hmmm.....the springs in the clutch plate looks as though something was rubbing against the springs but don't see anything on either the pressure plate or the flywheel that looks like it would've contacted them. so i dunno. gonna just go ahead and buy another disc and flywheel but wanna make sure this doesn't happen again. but kinda hard to do that when i don't know what could be causing it in the 1st place. ya know?

what would happen if a spring popped out of the clutch disc? have a friend who had an act 2900 who had that happen but forgot what he said the symptoms were.

spring in the hub pops out, buy new disc. End of story. Don't want springs popping out? Buy unsprung 6 puck. Then buy new tranny

End of story. Welcome to the problems of high HP dsm drivelines.

spring in the hub pops out, buy new disc.

huh? sorry, what's the hub part? whatcha meaning exactly? gonna buy a new disc, but just wanna understand exactly what's going on in there. maybe i just sound stupid cause i just woke up. well, that's the excuse i'm going with anyway.

hub = center Center of the entire disc that contains all the springs, that's teh hub. When you get the clutch too hot, shit expands. That's how the springs come out, when the clutch gets too hot. The way to solve that is to get an unsprung hub, i.e. puck style disc. This puts a LOT more strain on your drivetrain tho.

okay but when a spring pops out, what happens? what does it cause? what does the spring do anyway? and what would happen if the springs were just loose? wondering what caused this......it's pretty new.

DRW · Mar 10, 2004

From what some friends have told me, when a clutch disc spring pops out it makes grinding, scraping, and/ or rattling noises, depending on where the spring gets stuck. The rattling noise you first heard might be a loose spring rattling around in the disc before it pops out of place. If a spring comes out it can also cause problems with clutch engagement.

A general rule of thumb that I use is; If you find something broken or excessively worn, fix it, even if you don't think it was causing the problem.
