replacing cam shaft retaining thingy with eccentric

Use a drop of loctite on the bolt. Make sure to line up the eccentric and cup washer correctly. Make sure the clamp load is applied between the cam and gear. 65'
How do you ensure the correct clamp load is applied? Is that dictated by the rotation of the cam? Is the key on the nose a marker? Where should it be located, ie 12 oclock?
