I have a newer style level 7 Cartek clutch, i have about 3,000 miles on it, havent taken it to the track yet.....for the last month and consistently getting worse, when i take off from first gear, right before the the clutch is all the way out, it makes a low-pitch squeal, almost a growling sound that i can feel in the clutch pedal and shifter, if i push it back in it stops, seems like when i try to take off easy from a stop (maybe slightly slipping the clutch) it wants to do it, it only does it from first gear and is fine when im going through the gears, but if i kinda take off hard it doesnt do it, and also seems to get better after i go out and beat on it......im lost, please help me

 

anyone ....TTT

 

my textralia does the same thing.

 

Is it a high pitched squeal (like squeaky brakes), or is it a low-mid pitch "squak" sound (almost like a grinding/grating vibration)?? Does it still happen if you slowly let the clutch out at idle, without touching the gas pedal at all (on level ground, NOT uphill)?

 

Doesnt seem to do it if i let the clutch out slowly and not touch the gas.....and yeah, its a low-mid noise and vibration this is really not that loud but can be felt in the clutch pedal.....other than that, its good and grabs really hard....i heard if it was a bad pilot bearing, it wouyld do it all the time

 

A bad pilot would stop making noise when the clutch pedal is held down since the trans input shaft would stop turning inside the pilot bearing.

 

when it does the noise, if i push the clutch back in , it stops....but why would it only do it when i take off easy, when i quickly release te clutch and take off, it doesnt do it....also wouldnt it do it all the time , shifting through the gears, only does it when i take off form first, seems like it even does it a little if i down shift through the gears at about the same place of relaese when im going from a stop

 

clutch chatter... it happens

 

it chattered when i was breaking the clutch, in but it stopped......this is different, its an actual noise

 

is it a sintered iron disk? its just the way it is...unfortunately

 

Cartek does use a heavy duty, racing type lining/friction material, so it could act a little like racing brake pads, i.e.; it performs/acts/grabs better the hotter it gets, and they are generally VERY loud up until that point. Maybe it just needs a good amount of heat build up until it's quiet. If so, this is a small price to pay to have a clutch that will hold up to A LOT of abuse.
