I think what he is saying is that the problem occurred when the pedal was depressed and thus making the fork an inch away from the stopper. Others are saying that this problem happens when the pedal snaps back and travels beyond what the stopper would allow for. However there have been a few incidents there have been situations where the TOB circlip simply breaks (maybe from pressure) and those cannot be resolved by a stopper or triple ringing.

I'm not sure how you can fix that problem unless you convert to a push style TOB.

 

Quick question i have a stage 4 exedy triple plate clutch in my 2003 evo 8 i only have 61k miles on the car about a month ago my clutch stopped disengaging all the way could the tob be the problem cause it started after a 8k rpm shift from 3rd to forth on a onramp just thought i would ask before i start taking **** apart

 

If your pedal just fell to the floor then it is probably your clip. Look at the clutch fork. If it is all the way to the drivers side than it is a popped clip.

 

It has a little back and forth play when you wiggle it put its not all the way to the passanger side

 

The pedal pressure did not change at all it just stopped fully disengaging so my first thought was slave cylinder or clutch bad clutch fork but this is my first import car so i know its alot different than domestic so im not to knowledgeable about them yet

 

This just happened to me too on a new act clutch and only a little while after finishing up my build. Just wondering if anyone has looked into the act monoloc one piece wedge collar ?

Clutch fork stop, really damn close to the fork=problem solved. This happened to me on a 2-3 quick shift while doing a datalog. It sucked.

But you have to adjust the clutch fork stop and give it id say 1/8 inch space and give it a little room otherwise the clutch will slip too because it needs to be able to flex a tiny bit.

 

This happen to me also. I was on the dyno and after one or two pull the clutch padel when to the floor and we have to stop the tune.

 

The tuner tell me that I need to get a new act clutch clips and that It going to cost me $600 for them to install it in. What a waste of money because the act clutch is new also.
