I changed the friction plate and throwout bearing two years ago when I rebuilt the transmission, so far so good.

I seem to remember "back in the day" that there were limits for pressure plate wear, although I agree with most that it's the spring pressure that is most likely the reason why the pressure plate would not be reusable, mine had around 70k on it when I changed the friction plate, I am now just about to go through 100k.

It seems to have just become the norm now to swap out the pressure plate without really knowing why you are doing it.

I work in the Aero Engine industry and we see the same mentality there, when an engine comes off wing early to have a failure fixed there is a whole list of stuff people want to do to the engine "while i'm in there". My take is that if you were happy to leave it on wing and go flying then you shouldnt be "fixing" it whilst its in the shop, the components are designed to go for a full life why change them half way through.

The same goes for our P cars, components were designed for a certain life.

Just my 10 cents.
