Take a look at these scratches on the rotor bearing.  The photo is not
that clear, but these marks are not the puzzle joints.  I can feel
them, but they are too shallow to catch a fingernail on.   This rotor
also was corroded and I am still trying to get the side seals out.   I
have not dipped it in parts cleaner yet.   Is this thing a boat anchor?

Strange. If in doubt Jerry put a new bearing in.
I think the parts cleaner might eat the bearing anyway.

Looks bad to me, Jerry.  Are the side seals stuck in their respective
centers (of their seal groove)?  One trick I use is to use a bad side seal,
break it into a smaller piece, then lightly tap it up against the stuck
sideseal,
with a hammer, via the corner seal groove.  This usually works if the groove
itself isn't warped or sticking the seal due to overheating or something
else.

Paul has a point on the bearing.  I would press it out if you're going to
dip it.
I recommend using a product called Zep Industrial Purple Cleaner.  I use
them
to get rotors cleaned up to a bright, shiny finish, completely carbon free.
Let
the rotors soak in a diluted solution of about 1:1 Zep & water, in a garage
bucket, and with a brass-brush, scrub the crud off.  It should get in those
side
seal grooves and get the mess out.  It ought to help in aiding getting the
seals
out if they are stuck due to corrosion, rust, or some other unknown "funk".
Use rubber gloves!!! That stuff is very strong.

Good luck,
