NB - if you look very close at the pic I took of the old impeller still sitting in the housing you will see that it is in fact not centered but slightly off center. Notice the fins towards the bottom are slightly more bent than the ones on top?
It's not huge but it's definitely not centered. I assume there is a reason for it although I can't tell you why it would be done like that.
An interesting thing to note. This is the first time this has been done, so all these parts were 9 years old. The impeller looked like new but and interesting thing that I noticed was the seal on top of the housing was showing some significant 'dry cracking' and I suspect that it wasn't to far away from leaking. I also noticed the replacement seal had a much wider 'skirt' on the bottom. where it squashes against the pump housing.
Kinda cool to see one of these things disassembled partially for those that never have.
