No sign of any seal leaks. It looks like the front bearing is bronze, and
is just worn out (motor shaft wobbles when I turn the rotor by hand).

I found the slot in the rear of the shaft behind the cap, but the impeller
is on too tight. I finally got the motor front housing off and the rotor
out, so I can clamp the rotor in a vice. I still can't budge the impeller.
With the scroll around it, I can't get anything on it to unscrew it (and I
AM turning it in the right direction) and it's too tight to reach in and
turn by hand. About the only thing I can think of is to make up some sort
of clamp out of aluminum plate, that clamps onto the impeller outer
diameter, and then turn it with a wrench of some kind. Lot of work to just
try and salvage the pump. I've also tried a strap wrench through the outlet
hole, but there wasn't quite enough room. Frustrating.

Did I mention they can be a major pain in the ass? I'm having trouble
following how you got some of it apart without taking the impeller off
first. Some of the brass impellers have two holes for those special
wrenches that I can't recall what their called, you could drill your
own. Leather gloves or an oil filter wrench are about the only options
if its plastic. You could destroy the impeller and clamp the crap out
of the rest it with vice grips, it has to come off dead or alive.
There are many types of wet ends, sounds like you've got one of those
horrible ones. You've got to understand that its been in chemicals for
years.

I only dick around with them for maybe 15 mins. and can see that it's
time to break the bad news to the customer.
