Whirlpool 840 Series Dishwasher (5 yrs old) Pump Housing leaking

First let me say this is an awesome website. You've already helped me diagnose my icemaker issue.Need A Part Start Here
Now to my dishwasher. I've isolated the leak to the pump housing. I've removed the housing and motor assembly from the dishwasher and was hoping to be able to replace just the pump housing.
I can't quite figure out how to remove the pump housing unit from the motor.
There are three screws that attach the two together (those were obvious), but how do I detach the motor shaft from the housing?
I'm sure it is rusted on some, but is there a special procedure to remove it? I see the little medal clip on the shaft near the base of the motor, but there's got to be more.
You can't exactly pry on it too much without risking damage to the motor disk.
Is it possible to replace just the pump housing, or do you recommend buying the motor/pump as a complete assembly? I was hoping to go the budget friendly route, but I'll do what I need to do.
For reference, the housing is part # 3369011 and the motor is 8283457.
Thanks so much for your time. -Blane

Unless you actually see a crack in the housing I believe the leak will be due to a bad seal. Typically for Whirlpool you can seal kits that include all the seals in the pump then you go in from the top and replace each seal. I am not sure about this pump without a model number.
In regards to your question once you get the screws loose it is just a matter of getting the motor out of the housing. The seals hold the motor in that I am referring to which are inside the pump housing. Also there is a pump impeller attached to the motor shaft inside the pump housing that will have to be removed from the topside.
