Positioning foil removal of speedmaster sm-52

So basically the clamp for my plates is not opening properly. It’ll open sightly and I’m having to push my plates underneath the clamp. I only heard air coming from the panel that covers the gears and found that the lip seal inside the air housing was gone and I’ve replaced that but the problem is still there. The only other thing I know to do is to replace the air bladder that opens the clamp but I don’t know how to get the plate cylinder foil off to get at the bladder. I’ve removed two bolts that seemed to be holding it down but it doesn’t come off or budge at all. Does anyone have a how to or write up on how to get that foil off and get the bladder out? Thank you in advance

 

hello dear sir, could you show us pictures that illustrate your words so that we can help you. thank you

 

what do you mean by foil ?

 

That panel is spring loaded and has to be removed carefully it's a two person job call a tech.
