So I was changing my buddies clutch for him and started thinkin ... and wondered if anyone has thought about or tried this ... what if you were to put an extra plate in - mechanically speaking it would appear to remove the extra room and prolong the life of the clutch .... make sense to anyone else?

 

yep, I thought about it before and then found out later that d-aces cory does that. My friend's clutch started slipping like a month after he put a new one in (barnett) so we just threw in another steel plate and now it works great. The next time i take my clutch cover off i'm putting another plate in.

 

explain?????

 

by taking up that extra room it puts more tension on the springs. might make it harder to pull the clutch in. also, you would have a steel up against the pressure plate which might be noisy being that it is metal to metal. all i can say is try it. worst case is you might have to replace the pressure plate if the steel decides to chew it up, but i doubt it.

 

Its Called The Stack Height

 

I wouldn't do it. Steel on Aluminum as said above. I bet the pressure plate cost would be greater then the cost of new fiber plates... I doubt the clutch would disengauge with an extra plate, steel or fiber. Beefed up springs is what worked for me at a cost of greater clutch pull effort.

 

Measure The Stack Height Of The Steel And Friction Plates Out Of The Clutch With A Micrometer.then Buy One Steel That Is Thicker,every Model Has A 2 Oem Steel Plates One Thicker And One Thinner Than The Rest And Get It At The Maximum Stack Height For The Model Your Installing It In.stiffer Clutch Springs Too And It Will Grab Like A Son Of A *****

a few things need to be cleared up here
When a clutch starts slipping from normal wear, it is becuase the fibers have been worn down thus making the stack height shorter. When the stack height becomes too short, the pressure plate "bottoms out" agianst the clutch center. The only ways to fix this is to keep it from bottoming out by grinding away at the clutch center and the pressure plate where they are bolted together, or by increasing the stack height by putting in new plates or by adding a steel plate. Putting in stiffer springs will do nothing to fix this.
On f4/i's there is plenty of clearece for another steel plate, and since the clutch throw is like 3mm, it will disengage just like it's supposed to (you will need to adjust the cable a little). Adding a steel plate will not make the clutch pull any harder. The effect is the same as putting in new fibers, only it will last MUCH longer before slipping again.

 

If you put the steel plate next to the pressure plate, there would be no friction between the steel plate and the pressure plate because they both would turn with the clutch center. On f4's the extra steel plate doesn't fit right up against the pressure plate, so on my friend's bike i put it next to another steel plate. Again, there would be not friction between the 2 steel plates because they always turn at the same speed.

 

Yall know what the judder spring on the Honda is? Well take that out and the judder spring seat and then get rid of the special friction plate( the thin one) and then put in a regular friction plate. Problem solved.

 

Ooohhhh I get it... It would spin with that part of the hub!!!!


Didn't think of that myself.. So it would just act like a spacer.

 

good **** ... so i wasn't stoned when i thought it made sense ....

 

post a pic or something. im lost.

 

like schwartz said you have some good solid info. however, the higher the stack height, the higher the pressure plate. the more the pressure plate goes up, the shorter the springs will be. therefore, more effort is needed to disengage the clutch. now, i dont know if one plate will make all that much of a differance in clutch pull or not. ive never tryed it but in theory it will get harder. how much? i dont know.
