How do I remove Saracen bayonet shootbolts from a window?

[nickalouse]

I've been searching on forums, youtube etc, but I haven't seen instructions on how to remove the bayonet part of the shootbolt extensions from a window (These bits).

The closest I came was this post (on this forum), and this video (on youtube). Neither tackle the logistics of the mechanism being in-situe.

I'm told it's a case of pushing the shootbolt extensions in hard and twisting anti-clockwise, but that just unscrews the threaded rod. I can't get hold of the other part through the handle holes, or through the hole where the shootbolt extensions come out.

I didn't really want to whack something into the end of the extension tubes, as I'll then have to buy a new pair.

Any ideas?

So you want to change the gearbox part? If so you need to unscrew both shoot bolts and the handle.
Not a fun job to do in situe, I wold defiantly recommend taking the sash out if possible
