The new king pins and swivel bushes has arrived from Ian Harris. And the thinking starts 😀 How to remove the old bushes? How to press the new ones in? And how to ream the bushes to a perfect fit for the king pins? 
Well, my local expert in machine works has to be consulted. And that was really a good help. First he helped me with a tool to hammer the old bushes out and the new one in – it was only a couple of minutes work by the “svarv” (turning machine??)! 
Then he lend me the right tool to ream the bushes – a adjustable ream with a proper guide to ensure that the two bushes are perfect aligned.
Bur first the old bushes has to be removed. The tool worked perfect… very simple to tap the bushes out!
Then it was “a piece of cake” to tap the new bushes in place. 
Then the real work began. In small steps the bushes vare reamed to the right fit. About a 1/50 mm a time it took it’s time but the result was excellent. After a hours work the king pin had a good “push” fit.
