[C320-list] Impeller cover damage

I've found that the easiest way to compress the impeller blades is to
use a larger size hose clamp. If you tighten it to just the right
diameter the impeller can be worked into place rather easily. It takes
a bit of trial and error however, and you want to be careful to avoid
damaging the impeller blades.
By the way, I second the SpeedSeal suggestion. I hated dealing with all
those little screws before I made this change. They are a bit pricy,
but if you ever have to change impellers in a tight spot you will think
it a reasonable investment, I'm sure.
