Rear tire removal

Hi,
I'm trying to change the rear rubber and in the user manual it says to disconnect a bunch of things that get you to the rim removal.
One last step before sliding the rim, is removing cone shaped aluminum spaces, Seen Here on the 3rd picture.
There is no easy to apply extra force as it is inside the cavity, all you can do it to put your hands in and pull.
I've tried that, tried heating it up a little, a lot and using gloves to pull, nothing.
I'm looking for any other ideas.

Careful in using heat. It could damage the bearing seals.

What is the proper name for the part you are trying to remove per your manual? Would help in identifying what you are having trouble with & also help someone give you the right answer.

If I recall correctly, just called spacer.
You can see it in that 3rd pictures.
Looks like under normal circumstances one can simply pull it off by hand.

It's called the inner side collar. It should just slide off, no puller or heat or anything else needed. My first suggestion is to give it a few good taps with a rubber mallet. My second suggestion is to spray some PB Blaster or similar solvent in there to work on any oxidation, baked on grease, etc and let it soak in for several hours. My last suggestion is to use a can of compressed air like you use to clean computer parts and spray the shaft liberally with the very cold air. If the shaft shrinks enough, some more mallet blows might get it loose.

I'm wondering about a back and forth motion by holding the front and back of the tire. I've done this when removing wheel bearings on a car and wonder if it would work in this situation. I've never taken one off a Wing so I don't know. Just suggesting.

I would try what Dale N. said after leaving some PB Blaster or whatever soak in and taping it with a hammer.
