You should have 1 to 1-1/2" of free play at the top of the pedal.

I’m not sure if the throw out bearing will constantly ride on the clutch fingers but I’m pretty sure your return spring will try to push your bearing into the fingers

A throw out bearing is intended for intermittent use when the clutch is used. To have it in constant contact with the pressure plate will burn it out in a very short time as it is not intended to constantly turn such as a wheel bearing is.

The return spring pulls the T/O bearing away from the p'plate 'fingers'.
The pedal freeplay is the 'gap' from T/O to the fingers.
The freeplay in the pedal becomes less, as the friction plate wears and the gap from the f'wheel to p'plate becomes less.

Lumpy, wouldn't the gap become bigger as the plate wears, giving you more free play in the pedal? I am not questioning you just trying to learn for future projects!

No as the disc wears the fingers of the pressure plate move inward which means the other end moves outwards towards the throw out bearing. I hope you understand how I'm explaining this.

It makes a little sense I'm not totally grasping it though [emoji848]

I was a bit concerned with that also, so I installed a return spring for the clutch pedal. This keeps the pedal all the way out when not in use.

As the friction plate wears. The pressure plate comes closer to the f'wheel.
That in-turn, raises the 'fingers' of the p'plate higher above the pressure plate's cover, and closer to the T/O bearing.

Since the fingers act as a lever, their fulcrum is in their middle. One end touches the pressure plate, the other the throw out bearing. As the throwout bearing pushes their end forward, the other end pulled the pressure plate rearward, away from the flywheel, releasing the friction plate. Think of a see saw. One end goes up while the other goes down.
Now, when Lumpy said the free play decreased as the friction plate thinned due to wear, that took me a second to wrap my head around it - but applying the see saw principle clears it right up......

Okay okay that makes a little more sense. Thanks everyone for helping me understand that
