Yes, it should not be that tight, not loose either, as soon as it stops turning with my wrench(the bolt) I turn it 1/8 of a turn more, that's it. You should be able to turn the disk by hand easily, not freely, but it should need the same force to turn from start to stop, as long as you don't feel there's like an extra torque to start moving it and then it reduces the amount of force, if that happens then is too tight.
