Cleaning the bearing, and my "Thrust plate support disc", the thicker metal disc that goes under the thrust disc, has a dimple in it? Is it quite deep (1/3mm or so)?
From the various pics on the internet it looks vestigial, on mine it's quite pronounced. Is this support disc meant to be flat or dimpled?
