How does a sprung clutch work?

[born2drv]

I just got my HPF full-face feramic clutch in today, and I've always wondered, how exactly do the springs work as far as smoothing out the transmission? What forces do they absorb and how? I can't see how the springs make contact with anything moving to expand and contract? It looks like there are just 6 springs wedged in there....

Thanks!

the clutch is made of 2 pieces and the springs are set between the hub and the clutch bodies. When you slam it ( drop the clutch, or even ease into it), the spring dampens the torsional force. I know it looks like its just one piece, but if you give it enuff force you'd see the springs compress some

thats what i thought too... but between all the 6 springs, are 6 pins or whatever that hold the hub and the plate together.... so i thought that kept it rigid making the springs pointless....

so i guess these pins also bend during high loads? i guess it's only supposed to be a very very small deflection?

make sure you dont use an aluminum Flywheel they WILL weld together there has been two of us on here in the last month that they did not tell that to. We both welded together on the first burn out we did.

whoah.... what was that about aluminum flywheels??? Im doing a clutch job very soon and I was plannin on puttin in a lightwheight flywheel.... I dont wanna do that??? Or is it just on certain clutches?
Thanks you might have saved me alot of time and money.

Aluminum flywheels use steel inserts. No different that an all steel flywheel.

B2: The Centre Hub can move independant of the Rivet Pins the springs are between the facings and the Centre Hub.

Very different actually using the feramic (fullface)clutch creates much more heat since it has a much higher melting point which the AL FW cannot dissipate fast enough so the two get welded together the stock FW is all steel so disspates the heat there have been two of us in the past month with the same setup in which this has happened to Ive used the AL FW with other clutches but Im refering the Feramic in this post. I should have specified in my post.

Son - Put the crack down. Please.

Aluminum not only heats up faster than steel, it dissapates heat twice as quick.

As for welding clutches together - you've put something together wrong.

Wow why did two of us with the same setup have the exact same outcome HPF told me after the fact that this clutch does not work well with an AL FW if you put the two metals together the small disk cannot dissipate the heat fast enough Im well aware the aluminum dissipates heat faster, nothing was put together wrong.

Being that there are thousands of aluminum flywheels in use on many different makes and models that work fine I would have to say that the problem is
1. Disk material(HPF)
2. Operator error (excessive slipping of clutch).

That is what I was saying is the disk has a very high melting point here take a look at this thread
