Okay, Bought a Meizere HD pump, i was trying to press the old impeller out of the housing and the housing cracked, so now Im buying a used pump and going to try again... I keep reading that it just pops right out but I didnt have that luck, it wouldnt come out of there for anything... Any tips or helpfull hints on removing the next one.

Mine was a real PITA. I used a screw driver on the shaft and beat the heck out of it until it finally went out the back. I ended up bending the impeller up pretty bad, but that doesn't really matter of course.

 

Okay, i figured out what i did wrong, by looking at those photos. thanks for that post.
