Do you mne tou kind of made sleeve from delrin and placed in between bearing and the rudder shaft?

Not a sleeve, just a washer placed immediately under the clamp at the top of the rudder shaft. See attached photo.

Thank you, now clearly understood. In my case this will not work, so Im tryng to figure out how to grow on new sleeve or something to get rid of that sideways shake. There is option to cut of from the top of shaft and lathe exact detail and weld all back together.

I am assuming that the rudder bearing was not made with the rudder shaft close by for continuing to measure the bearing against the shaft.. I would say you perhaps had it made in the as new shaft diameter and not what it had worn down to.. because if you had continually measured and tried the bearing for size then this would not have happened.. unless the bearing has not been made to the correct size Ö

Well, to be honest if as you say the shaft is worn where this bearing goes, then Iím not surprised, as I say it needs to be measured and the bearing made to fit.. 🤷‍♂️🤷‍♂️ I would suggest you ask for your money back, get some Vesconite tubing , it is far far superior to Delrin, and make it, get a top bearing made to fit

Have you spoken to Jafa and are you getting a new one made if so if Jada are going to make you another, measure the shat wher it is contact with the top of the bearing and the bottom of the bearing.. And get machined to those measurements.. so itís a tanker if you will .. but itís really better if you have the shaft with you when machining the bearing 
Good luck 👍👍

Yes Holby, thank you. I got super good support from Jefa and they suggested to put sleeve on top and send new bigger bearing. Also, finally after seeing my old ďbearingsĒ I now in full understand what you meant. I didnít expect that old ones werenít literally bearings.
I hope good people at Jefa donít mind me sharing this instruction, it is exactly how Iím going to install and might be useful for someone in future.

If you put a hard metal bearing in then I feel you will be adding issues further on.. 
i would suggest sticking with polymer bushes as that is how it was designedÖ
For me Delrin material I do not think is the right material as vesconite has since been developed and is easy to work with.. I do not have any financial link with vesconite.. 
here is their website that shows their material.. 

If you go back further on here you will see photos of the bushes I made and if I can make them then Iím sure anybody can.. 
but what ever way you go go lunch and enjoy..

I am still concerned that you are buying a bearing of the shelf.. as the wear on the shaft is so variable.. but 🤷‍♂️🤷‍♂️
