On a modern diaphragm spring clutch that I've installed had instructions to hammer down the fingers that weren't even. I'm not kidding. they said hammer. Mine were all even, so I didn't have to break out the hammer.
Ya, that does sound odd, I don't think about bringing out a hammer to "adjust" a clutch. Kinda' like when putting a battery in the vehicle, batteries and hammers don't play well together.
