New Holland T7030 lower link sensing pin removal

[JeremyD]

Trying to remove lower link sensing pin to repair lift arm end where the ball is, as it is breaking up. I bodged it in past on the tractor but it needs to be removed to weld up properly now.
I have removed two allen screws should the pin come out now? Do I need to remove circlip holding sensing wire? Or best left in? Any advice appreciated?

I did exactly the same a few years ago for the same reason. I tried everything but could not get them out. Ended up heating them just to get them to budge and replaced them so to get tractor sorted and going again.
Think I tried to wedge a chisel between the C shaped flange and the tractor and got a pin on the other end and the biggest heaviest sledge hammer, theres a roll pin I think in the flange to stop it turning so it won't slide off the draft pin until its started to come out and mines were that stuck I bent the flange trying this.
