Make sure the spring is installed during reassembly, or the ratcheted adjustment mechanism will not work properly.

How? There are no photos of how to install the spring, and there is no obvious way to install it. The only photo there is doesn't help, as the spring is mostly covered by the adjustment strap.

I hate this guide for not including the pics for the spring. You don't happen to still have the pics, do you? The imgur link is dead and I've spent the last hour or so trying to fit the spring, but I can't figure out any way how. Would be a lifesaver if you could share these pics again!
