Nord Stage Key pivot broken

Hi,
Just bought a few key pivot to fix a broken one on my Nord Stage ex.
Does anyone knows how to replace this part properly? (really don’t want to mess it up)
Thanks in advance

I can’t think of any keyboard repair task that is as trying as this one, I’m sorry to say. That pivot mounts onto a metal rod that typically runs the entire length of the keybed. That rod has to be pulled out enough at one end to insert the new pivot - and of course, the pivots for the other keys will fall out as the rod is removed. Getting that rod out will have you losing your religion. Sometimes pliers and some good yanking will do it, but often it will require a pair of vice grip pliers firmly attached to the rod, and some good hammering onto the vice grips.

My condolences.
