One I would make sure I had a gasket between the two halves, if so, take a heat gun and heat of the area it is rubbing and push it out a bit. These covers are not made the same due to them being plastic and cooling down to different shapes.
Lastly make sure something is not wrong with the clutch that is causing it to hit.
