Akela/Kratos/Caden Power adjuster O-Rings

[Knothead]

Have any of you serviced the O-Rings on one of these?  My Akela is puffing our the slot side.  I can hold my finger over it and puff it off with the shot.  It would appear that you remove the screw, spring and detent and then slide the adjuster (power wheel) out.  Just wanted to ask first in case something inside will shift that I don't see in the video from Sub12 Airgunners on the tube.

nah, it comes right out simple .. that whole area is full of sharp edges though that need to be wiped off with 600 grit or its probably near impossible to get the rings in there without peeling something off .....
