Problems with assembling the Nexus Inter 8

[Nexus1947]

Who can help me?

The part In the picture below, shown by the arrow has fallen apart into 2 pieces. I have to put them back together, can anyone help me with this? Because it seems like there are more ways to do this and I want to be sure I have done this correctly. In particular the position of the ground plate with the palls.

If you are unsure how to reassemply it I would think that downloading an "exploded view" of the hub from the net would help. Its like a drawing. Otherwise I would just send it to the lbs for reassembly.
