I've got a copy of the bulletin from Chance -- all they say is not following the order can cause serious structural damage and possibly personnel injury.
Judging by where they are and what they do, you can crack/warp the wings, and cause cracks/damage to the center axle. Depending on how things go, you might run into bent sweeps. It's been several years since I worked on a Century Wheel - so I'm going mainly on the paperwork I have.
Attached are the pages from the Service Bulletin from Chance regarding this issue.
