Help with G&G GR15 Gearbox

Trying to put in a new spring have gearbox out of the rifle.
This version has a pneumatic piston that gives the gun that bolt action through the ejector door. Have a really hard time figuring out how to get it off of the gear box casing. It's attached to the top edge of the frame holding the two halves of the gearbox together.

Does anyone have any experience with it. Found great videos on you tube, but none that shows this same sleeve over top. On the manual it's called the pneumatic blowback piston

Thanks
