Steelcase Leap Chair

I Run A Warehouse That Stores These Things By The Hundreds And Distributes Them All Over Campus. We Also Collect The Broken Ones, About 80% Of Which Have A Failed Piston. Is There A Way To Replace These Things Without Completely Disassembling The Chair? I Need Help To Convince My Employers That It Makes More Sense To Repair These Things Ourselves- We Could Be Making Donations To Schools And Churches Instead Of More Trash. Thanks!
Does Anybody Know Of A DIY-type Site That Might Give Some Handy, Easy To Follow, LEGO Style Instructions For This Endeavour?
