you know there are 2 small tabs that if you line them up,then barely turn the hat,the hat will sit flush and will hold its self down right? then you just put the lock ring on and use 2 screwdrivers at the same time to rotate it,one screw driver on each side .getting the tabs lined up and getting the hat to sit fluch before messing with the lock ring is the key.
yes i notcied sometimes it would hold itself down and sometimes it wouldnt, but still was unable to get the dam ring on. Can u explain a little better about these tabs please!
