Rudder shaft lock nut removal

Hi
I'm trying to fit new rudder bearings but have a problems to remove the rudder shaft lock nut. Is it done with a special tool or move? I can't make it los.

Hi
Guess you tagged this on to one of my old posts?  I seem to remember as in my original post a locking grub screw which is at  side of locking ring that need removal first then you need a 2 pronged tool which is used to turn the ring to remove it.  Think it's called a 2 pin spanner wrench, it fits the indentations on top of ring.

After removing the screw which pinches the thread to lock the top nut, the nut turned easily by inserting two screwdrivers into the holes and a bar across them. If not, try lifting the rudder from below to unload the nut.

hi
this is the right spanner

Hi I did the job of removing the rudder by jacking up the ruddy ever so slightly, inserting 2 Philips screw drivers into the holes on the nut and a 1 foot wooden bar and just inserted it in-between the screwdrivers and turned it. Remember you have then to dig a hole to get the rudder out or re-lift the yacht

I have the opposite problem. The nut disc is loose and slackens as we sail. A previous owner has used graphite grease on the rudder shaft and locking disc. Has anybody used a nylon lock nut or something to stop the nut disc up turning while sailing?

You shouldn't have to do this - as stated in a previous post there is a grub screw which, when tightened, distorts the threads and the nut will stay in position.
