Next dozy question

Rear wheel recoated, circlip and seal in place, new cush rubbers drive plate in place. Question: how do I tell if the plate is fully home and will the retaining ring pull it down when I sinch down those three small screws?

Bit of a newby question but sometimes it helps to second guess yourself.

Thanks very much

If a Tonti big-block I think the ring just a trim that covers in the circumference, doesn’t hold in the centre part.
