Screw Caps (four)
Once you have removed the platter, prise off the rubber caps with a screwdriver to then unscrew the platter support base.
The Platter Bearing
This shows the bearing after the captive nut has been removed ...
Platter Bearing Nutt
Unscrew the bearing nutt that fixes the bearing in place.
There is a transparent 'film" that you might miss that you need to remove to access the screw lift holes.
Lid Screw for lifting platter
Use two of the longer screws from the lid removed earlier to act as platter "lifts" to protect the bearing when lifting off.
