    Looks like this may be a 6 speed, so no clutch life readouts...

    Like open heart surgery, I cringe seeing it all opened up like this, yet so very fascinating :)

    looks like the rivet at 9 o:clock just started to get worn - if that is the case, certainly not much life left...

    Its worn down to the rivets and the sideways cuts are fully gone, f1 cars normally slip before they look like this. It would lock out of gear and slip in high rpm.

    I have a few questions that have confused me for a while , I am not sure if this is the right thread to ask , but i'll try. These questions are for everyone who can shed some insight

    1. As we know the TCU will tell the percentage of the clutch used. And I understand that it is a rough figure and can be played by changing the "closed clutch position. Assume that from the new clutch installed, the TCU was calibrated correctly, what will be the actual (physical) thickness of the clutch if it were to display 100% used ( 0% left).

    2. when you resurface the flywheel, any special machining tool used since the surface is tapered.

    3. in a perfect world, and assume all labor costs = 0. If I want to maximize the usage of flywheel , clutch disk, pressure plate. Assume normal usage of the car, what would you expect the ratio of life expectancies of these 3 parts? what i mean is that, for every clutch used to bare 0% left, is the pressure plate still having life left? if so, what percentage roughly. In other words, how many clutches replaced until a pressure plate HAS TO BE replaced ( no good no more). Same question for flywheel life, how many clutches replaced until a flywheel HAS TO BE replaced. Of course, I understand these varies according to usage, and I understand this is a guesswork, but whats your opinion on this?

    1. Its a manual car so I cannot check wear percentage with the computer. On F1 cars I start seeing them slip at 50% or less but normally the throw out bearing fails before it needs a clutch. Always replace the OEM bearing with a Hill engineering bearing to avoid premature failure.

    2. Yes its a specific lathe for resurfacing flywheels and we balance the flywheel/clutch together.

    3. Pressure plate and clutch are replaced together never replace just the clutch disc. I have only surfaced a flywheel 2x now and would replace it on the 3rd it depends how badly burnt up it is.

    Every car and condition is different so you just use your best judgement based off what is actually in front of you at the time.
