    Hello,

    Just purchased a 2005 - F430, the clutch use reading is 6,8%... only.
    I assumed the Clutch was replaced to have such a low value, but I don't have access to any invoices or service records mentioning the replacement of the Clutch !

    do you know how I can make a visual inspection and make sure it was indeed replaced, fixed, or can it be just a computer trick made by the service to lower the value on an original clutch ?

    Thanks

    How many miles do you have ?

    Yes ..from underneath you can look at clutch plates ..not exact science but you can see wear usually by the veins

    For what its worth when you perform a visual inspection, I took my used clutch out with about 64% life left during my EAG 6spd conversion and it looked very similar to my new oem clutch! Was almost tempted to put it back in!

    the issue is apparently using a computer connected to the car, you can reset the value to 0% of the clutch wear, even if you have an original used clutch ...

    Correct, it's easy to reset the clutch closed position new with a Launch or Foxwell. That would be crappy of a seller to pull that on you. A new one is about 5.6mm thick. You can see it from under the car with the belly pan off. I can go in my garage and snap a pic if that helps? My car is on the lift right now, as I'm doing a new clutch, headers, valve cover gaskets, motor mounts, etc (all the stuff to do while you're in there).

    I always worried about this for someone buying from an unscrupulous seller who would do this on a car with nearly zero clutch left. I guess similar to what they say in the watch world, "buy the seller not just the car".

    Curious can the Release Bearing be changed without having to drop the tranny? The Release Bearing seems to be often the cause of expensive Clutch replacements.

    The release bearing lives in the transmission bell housing so no :)

    This video is good to illustrate what's involved.

    Having had a release bearing fail and drop brake fluid all over my clutch, on my old 355, I would always change the bearing when doing the clutch. And replace with a Hill one.

    Thanks for this and yes I had a 355 also that the release bearing needed to be replaced before the Clutch wear but on the 355 as you know that is easy versus the F430. I would 100% change/upgrade the Release Bearing on a F430 whenever the Tranny needs to be dropped.

    There is no spec for unloaded clutch disc thickness because ... you cannot check it out of load.
    When under-load, the minimum disc thickness is 7.5mm

    Yes, it's a good illustration BUT you do not want to wear flip flops working around 200 lb metal objects.

    That means you don't do much backing up an up-hill slope. The F1 system always slips the clutch when R is selected, unlike a person driving a 6 speed manual. If you do that a lot, you would be lucky to get 22Kmiles from an F1 clutch.

    I knew it was a good idea to have circular driveway at home :) Still have to back out of the Garage but at least its a minimal distance.
