Normal periodic cleaning I'd do a wire cleaning tool to loosen "stuck" coffee and a can of air to blow them out.

I had to remove mine (Obel) to get to the top bearing. Putting it back is easy enough...but setting and seating will run and will take time and coffee to "run in" again.

Thanks everybody for the info so far.  I tried the screwdriver approach (insert the screwdriver through the opening in the aluminum casting where the ground coffee exits, right?)  Couldn't get it to budge.  Got nervous about applying lopsided force.  So I made a "puller" - piece of 1/4 inch plywood with three holes.  Plywood goes across the top.  2 inch screws go through the plywood and into the threaded holes for the burr.  Nice, controlled, straight up force on the carrier.  Still nothing.  Maybe I am being too careful, but I sure don't want to break anything.  Maybe I didn't get the screwdriver approach right (didn't do anything that even remotely put my knuckles at risk).

You can try an up and down shaking motion.  This helps mine pry free easily.  Once I did a complete tear down I could see the marks I put on the bottom of the carrier. Not much wear. I have used enough force to bend a screwdriver in the past. Once I saw the build of everything else I didn't worry much about the force I was applying.  Even if you take your time and use lighter force it will eventually come free.  Another approach (Not sure I recommend) is to unmount the motor and allow it to drop pulling the pin out from under the carrier.  Just make sure you disassemble the bottom and be there to catch the motor because it's heavy!  At least my MX motor is.  Again I wouldn't do this but it's an idea.  You could even cushion the barrier with the wood pullers you are using.
