BigRed350x Posted May 15, 2012 Report Share Posted May 15, 2012 Out of balance? Got any grooves in your basket? Usually the fibers breaking like that is caused by uneven distribution of pressure on the clutch plate fingers.... Quote Link to comment Share on other sites More sharing options...

sheerider11 Posted May 15, 2012 Report Share Posted May 15, 2012 Warped pressure plate, warped hub, or grooved basket. Quote Link to comment Share on other sites More sharing options...
Wheelman Chassis Posted May 15, 2012 Report Share Posted May 15, 2012 you sure your pressure plate isn't warped? maybe over tightening of the pressure plate as well. had this happen on my old zilla, i had over tighten the plate, broke the first two fibers. please explain how a warped plate or a grooved basket cause proken fibers?

Wheelman Chassis Posted May 15, 2012 Report Share Posted May 15, 2012 a warped plate can cause uneven pressure on the fiber causing them to flex. lol that would have to be a hel of a warp..lol Quote Link to comment Share on other sites More sharing options...
Tedder Posted May 15, 2012 Report Share Posted May 15, 2012 Want some broken steels to accompany those fibers? lol... Been there done that. We run asphalt - It's caused by clutch chatter You can usually feel what seems like the chain jumping the rear sprocket. Quote Link to comment Share on other sites More sharing options...

stroking Posted May 16, 2012 Author Report Share Posted May 16, 2012 yes its asphalt only and it did feel like the chain was jumping on the sprocket how do i fix this ? tired of breaking good clutches Quote Link to comment Share on other sites More sharing options...
Tedder Posted May 16, 2012 Report Share Posted May 16, 2012 There are a number of factors (sometimes a combination) that can cause chatter. When do you feel it? Mine was most violent at the 1-2 shift. Some days I can still get a little shutter depending on track condition/launch & shift RPM etc. Running on asphalt I assume you use a lockup? Do you use cork based fibers? Without getting into a big drawn out post my best advice would be to increase both primary spring pressure and lockup arm weight to stop the chatter then work back to find the combination that works for your setup. If you want to try one change I'd add primary pressure first..... *Once you get a handle on it and only in a pinch - If you have a little suprise chatter develop out of the blue a splash of GM limited slip additive can help tame it.

You asked it a while ago on another site. You didn't like the answers you got from Tedder & I. Your clutch tune-up is not happy. There are many fixes to the chatter, but you don't want to listen. You don't need to ask anyone anything. According to your times you were running in the past. You have the worlds fastest Banshee running low 5's & with sub 1.20 60's. You need to be sharing some of your clutch secrets with us. Quote Link to comment Share on other sites More sharing options...
stroking Posted May 17, 2012 Author Report Share Posted May 17, 2012 a splash of GM limited slip additive can help tame it. i seen some of this stuff in the parts store,but wasnt sure it would work guess i will try that and some stronger springs oh and i only feel it when i launch really hard in first gear Quote Link to comment Share on other sites More sharing options...
