Very risky in my opinion, especially since virtually all hard parts are now obsolete by the manufacturer. All it takes is a single small part, especially tiny plastic ones to break or any part for that matter to be lost, spring stretched, etc and it could be game over. Even if you were a master craftsman and could fabricate small parts, the fit and finish and tension of these small parts are critical to proper operation as anyone who’s worked on complicated decks knows, how finicky they can be. My philosophy is to disassemble as little as possible to effect a repair to minimize these risks.
