Yes, if the bellows has become deformed, you can try to fix it by removing the back or the lensboard and manually adjusting the pleats so they fold properly.
I'm not sure how heavy a 3221 is, but if it's the tripod you have, then try it out. You'll know when you need a bigger tripod. The head is often a weak point, particularly if it's the stock head with a smaller legset. Many of the Bogen heads have the platform sitting too high on a relatively thin metal support for a heavy camera with a long rail, that can be a big source of leverage.
