That's the new style with the boss hubs. They also changed the floaters to help keep the hubs from getting like that first pic.

 

hmm the one that is messed up looks just like the new one i ordered but without the notches...when was the revision done on the clutches? because i bought that hub and two new discs for my triple last summer

 

josh what you have is the newer style its not the latest version that is still in testing.

 

Ok thank you for clearing that up. I was confused as I got this clutch used with the hub pictured first, and I ordered a new hub (pictures second).

Fingers crossed I don't have any problems!!!

 

I want to order rebuild kit for my triple. who should I order it from so I get new revised disks.

 

Directly from Exedy to be honest with you. But the rebuild parts most warehouses have are the latest im sure. I am a Exedy dealer also.


============================

am i understanding this right? is this the difference from the old and new:

the old center piece in that guys hand has a chip/notch off the end of each tooth line?

and the new ones are fully solid with no chip at the end?

^ that's me sounding like an idiot.

 

Guys,

I have tried to find the pics I took of this latest design, but have since switched phones and can't find them.

The latest fix for this problem has nothing to do with the center hub. That's because they believe the issue isn't with the hub, but with what the top plate is doing when the clutch is depressed. If you notice in most of the photos its the top part of the hub that is worn/damaged.

So, what they have done is put these spacers between the plates that keep them even spaced, especially when the clutch is fully depressed. I was told that this spacer is similar to that which comes on the Exedy Twins, but I don't know for sure because I've not looked at one.

So, at this point I have no idea if this will fix the problem or not, but I told them I will get mine running and driving as soon as things thaw out here in Michigan and report back to them my findings after a few thousand miles of driving.

 

ah ok. im interested in your feedback! so will this make them chatter less also, or did they not comment on that at all?

I think my car is welded to the jack stands by now. its been on them for 2months now LOL

 

I do believe that this will result in less chatter though we didn't talk about it. But I do know that they believe that it's that chatter, specifically from the top plate/disk combo, that is causing the damage we are seeing. Only time and some miles will tell us if their theory is correct.

 

There's no chatter with the new floaters! I have about 1000 miles on them and they seem fine. It does seem to drag if i go up my driveway slow. I either have to double clutch it to keep from hitting my garage door or rip it out of gear.

You're correct.

 

Thanks guys. I think i might call exedy and see about getting the new parts. my clutch is fine, but its probably best to get the revised parts before something does go wrong.

teribble, you can shift the same quality with the new parts right? there is no high RPM lockout or anything funky occurring right?

 

I haven't tried to do any no-lift high RPM shifts yet. Its a little scary on the street with 700HP+. I'm waiting for the next track day to put it to the test. I'll try to do some this weekend on a back road and get back to you.

 

This would be good to know because I'm curious about this myself. Get out on some back road early in the morning and have some fun, dang it!

 

I don't get any lockout on 8900 rpm shifts but that's lifting on them. I don't think I'll have a problem but I'm also on a stock trans. lol

 

i wonder what would happen if you have the older plates and you send them back would exedy replace them with the new ones at a discount or replace altogether
