Problem when disassembling Shimano ST-6700 / ST-6703 shifters

First of all, thank you very much for your great videos on the ST-6700 shifters! Those gave me the confidence I could take apart my shifters, clean them, grease them and have like new shifters.

Unfortunately, I'm stuck at the step where the pin-screw is pushed out to get the shifting mechanism out of the handle. The pin / screw won't move one iota, on both shifters!

It looks quite easy in your videos, but no matter how hard I push (which is not maximal due to the position of the tip of the screw being not very accessible). I ended up using the end of the rubber-coated handle of some pliers in order to not damage the screw, have a little grip and being able to apply some force. But still, there is no movement - well other than to the sides / up/down, but not backwards.

I also applied some oil over night, but so far to no avail.

 

Any reason why the pin-screw wouldn't move backwards?

Any trick I could try to get the screw out unharmed?

 

Thank you!
