Hymer extendable table

[Gerh66]

Hi a pin has been displaced from my table and is no longer working freely.
Could someone tell me if there is something missing from the end of the steel pin in pic and in which order left to right the three components,brown metal,black plastic,white plastic in picture align up and where the pin joins them up.

Hope this helps, I can see I have lost a spring from mine that I didn’t know about

first time I lifted the middle bit out was by mistake I thought I had broken it
