Link with pix of clutch adjustment gauge.
I couldn’t find any info on adjusting the fingers and my F-04 manual didn’t have much on It. I bought it all from here and the measurement with the pressure plate flush to the flywheel is 1 7/8ths. The only way to get 2 inches is to loosen the pressure plate. Not sure if that’s the correct way...

All of what you said is great what you do not understand once the TO applies to the fingers when set up correctly you will only have 3/8” movement to release the clutch. It only takes .050 clearances at the clutch disc to pressure plate to fully release.
You can test this before you assemble the clutch on the tractor to ensure the clutch is set up correctly. Take the flywheel off assemble the clutch to the flywheel and gauge/test it. You can do this on the tractor but you will have no way to gauge what movement it takes to release the disc.
You can also jury rig away to check finger height use a level and a ruler and do the math. I have put more clutches in than the average bear and been bit a many a time. Clutch specifications are Top secret for some reason. About the only way to get technical is call a LuK help line they have the lowdown on most of it all.
Sometimes there are no silver bullets you just keep digging. You may have to disassemble it multiple times just keep reasoning you will find the answer. I don’t want to break your heart but in this process you learn to test the clutch before to bolt it all up.
Bring the tractor back together install a few bolts adjust the clutch (with the floorboard mounted) and check how free the PTO spins are the engine by hand transmission in gear.
