If this is the bearing you are trying to remove:
I'll tell you what I picture.
An oil filter wrench.
It's the perfect size to go over the bearing and rest against the plastic tub.
Slide a threaded rod down the center and find a big freaking washer the same size as the bearing. Line the washer up with the bearing, put a nut on each end of the threaded rod, and tighten those nuts until the bearing pops out.
