Started my project to change the kingpin bearings. Everything was fine until i tried to remove the old bearing outer races. The biltema 1" socket i bought today is going thru the race :angry:. Tried to reposition it couple of times but when i take the hammer it just slips through.

Is there any mm sizes or special type of socket i need to use? Or do i just need to buy more sockets and try what works? Annoying that everything else was easy and now i have a problem like this.

Do not buy the Biltema 1" socket for this task :).

What kind of socket you use to change the bearing race? I see in some pics 24mm socket? 1" sockets seems to be not too easy to get here.

Hi, Finland.

Probably need to go back to Biltema with ruler and pick up the next size available in mm. Anyone from Nordics done a kingpin bearing change with a Biltema tools? :)

Probably the current socket they sell in Biltema is just too modern and thin.

Biltema product number Art. 71-126 did the trick. Maybe would be useful to include this in the Wiki?

Biltema (scandinavian halfords) product number 71-126 is a 24mm socket.

But this depends what the outer diameter of your socket is, and that is up to the manufacturer isn't it?

Acc to my SKF bearing catalogue the 30302 bearing should have a 36mm inner diameter for the hole supporting the race, 42mm outer.

Yes, the biltema 1" was too small but the 24mm "heavy duty" socket was perfect for the job. If i remember right, the 1" was 33,3mm and 24mm 33,8mm.

I took mine out with a punch probably, or a chisel, never occurred to me to spend ages rooting around for a socket to hit. Bit of a swine working upwards too...

If it suddenly breaks, go back to the last thing that you did before it broke and start looking there :)
