Help needed to drop rudder

[Sneaky Pete]

Trying to drop the rudder on my Hanse. I have dismantled the quadrant and autohelm bracket. In picture 1 is the top bearing housing there is a collar under the white spacers with three grub screws to hold this in place. Picture 2 is on deck looking at the emergency tiller slot, the top bearing housing and the top of the rudder stock. I have removed the four screws only to see if I could get some movement they are I assume to hold the bearing housing. Also in this picture is two white plastic washers which rotate freely around the rudder stock but I am having difficulty removing them. I believe that below them will be some kind of lock nut which would allow the stock to drop through the bearing.
Question is am I going about this the right way and what do I need to do to drop the rudder.

I'd hazard a guess at the three grub screws being sufficient to allow it to drop (the weight of the rudder on my Dehler is taken by three similar grub screws). The four screws above appear to be to hold the fitting in place. As it clearly says Jefa have you tried e-mailing them?

Not e-mailed yet. Decided when at yard today to inspect the stock then hit this problem. I will sent something off to them.

Thanks for the web address I was on Jefa web site but did not see this. Now see what the problem is. The three grub screws hold the shaft in place, the bearing housing is a sealed unit so cannot tamper with it. I think the application of a heavy hammer should get thinks moving.

There is an aluminium split ring/collar on the shaft underneath the bearing, if it is like the tiller steered Hanse. This is to stop the upward movement from the rudder wanting to float upwards.The white rings just prevent aluminium to aluminium friction. You should be able to drop the rudder quite a way before you have to undo it. It is not connected to the bearing.
Yours does not look split & also looks a smaller diameter than the shaft lower down, so it may drop through the lower bearing without taking it off. You may still have to take the screws out though if the heads project too far
On my Hanse I just dropped the split collar out of the way & let the shaft drop out. ( after removing the gaiter) No need to remove the top bearing as it lifts off the top ,so if you leave it in place the shaft just slides down. It also stops the shaft waggling sideways for a bit as you remove it as you drop the rudder so I left mine in until the stock was out.

The best place for info is the "MY Hanse" forum

Yes a large hammer has done the business. Had to be careful that I did not damage the aluminium at the top. Could not believe that only three M8 grub screws hold the rudder in place and prevent the shaft from sliding out.

many modern rudders float so not much downward load
would think that there is drilled dimples in shaft for grub screws?

Yes three of them. They look like small countersinks will be replaced with the addition of some glue.

some locktite will someone might want to drop the rudder in the future.
