    do you have the right tool? Study the thread, you might turn the wrong direction instead.

    Have to wait for Clubsnap resident guru 'fatigue' to answer you, alternatively have to bring to Nikon Service Centre

    My guess is that if the elements are glued together then unlikely worth it to separate them youself, as they need to be realigned properly after cleaning, if not the lens will be de-centered

    after a lot of searching on internet i use alcohol to dissolve the glue and use 2 piece of rubber to hold the front plate n twist it out

    Oh my! You don't need to dismantle those to clean the optics.
    It's like you dismantled the piston just to replace the spark plugs.

    You also need to put some markings to return the retaining rings to the exact position.

    Although this video is not the right procedure,it might help you find the correct position of the tab

    The right procedure is removing the lens assembly from the front. There's a small screw on the side.
    You don't even need to remove the mount

    Such delicate procedures should be left to experts of the trade why risk it.
