[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.
