			Hi, you're nearly thereUse two jemmy bars or large screwdrivers at either side (eg 3 o'clock and 9 o'clock)
 then with steady prying pressure applied  place a piece of copper,aluminium,or hardwood on center bolt and give it a light tap with a hammer  not too hard and the cover should come off. you may need a friend to help as  a 3rd hand, you nod your head and he will hit it LOL.
 You can easily make a puller to pull the bearing out by using the center bolt.
 Regards  Brian
