Need help with original 737 control column elbow

[pierclav]

Hi all,

I am disassembling an original 737 control column elbow. I am done with the yoke end but the column end is playing hard to get. I have removed the pin and locking nut from the shaft but it won't come out. It looks like the green insert which appears to be press fit inside the tube is holding it in. Any suggestions?

Thank you,

Pierre
