Is the oscillating weight (not rotor) secured correctly to the oscillating weight bearing (the arm gizmo)?
Is there play in the jewel of the pivot for the oscillating weight bearing?

Any ideas? Its running Fine but the Rotor is scratching against the stem. It has noticeable play. Maybe a tap on the bearings?

If the jewels are not damaged, you need a new axle. 72203301400

Cant find it online unfortunately.
It's discontinued, so you'll have to be persistent...
