It is a little unusual for the top bush to be the one with play because it is usually the lower one that suffers from water and corrosion.

Remove the brakes, hub and the top trunnion and take the swivel axle off the king pin and examine it to get a better idea of the situation.

You don,t need any special tools to remove or replace the bushes, just drift them out and either draw them in with a nut bolt and washers or do as I do and drift the new ones in. Remove any burrs before reaming to final size with the special double diameter reamer. This is available to hire through the club.

King pin kits are available on Ebay, frequently.

If you do buy a kit, try the new kingpin in the existing bushes first. Often it is the kingpin that has worn and the existing bushes can remain.

:iagree: I find when you've dismantled them that the wear is almost always on the pin itself, rather than the bushes... :thumbs:

I've found that, with some of the aftermarket pins about, the new pin is too big to fit the old bushes and even putting the stepped reamer through it has made little difference. I've had to use an adjustable reamer to take a few more thou out...

I've also dismantled them to find that, on a previous repair, the larger end of the pin has been lightly skimmed in a lathe to suit the pre reamed size of a new bush. I've also found the remains of shim steel packings, sometimes strips of feeler gauges and even the remains of PTFE tape, though the latter is more often found on lower fulcrum pins... :whistle:

I dismantled the swivel axle today and took some photos.
The lower part of the swivel pin looks worn.

bottom photograph should not be a bolt which looking at the photograph would fall out if & it looks like the nut has come off, dangerous!

The bolt is banged with a hammer in the lower end in the picture, riveted??? (google translate).
So it can't fall out. But of course it should be an original "cotter".

Certainly a first magnitude bodge but I can,t see why it would be dangerous.

If it worked loose then the fulcrum [pin is unlikely to unscrew itself - they are difficult enough to remove with force, usually.

King pin would eventually wear itself on that hardened pin and start knocking which would give warning.
