Disassembling a TAC 2 joystick... please help me

Hi guys,
I have just received as gift a very used SUNCOM TAC 2 joystick.
The metal plate on the top side of the joystick has several and serious scratches. I think that the best solution is a painting/restoring attempt, but how to disassemble/remove this part from the plastic body of the joystick?
I found this picture on Internet,

But I did not understand if to unmount the metal plate the guy had to broke the joystick body or not.
Any helps or tips to solve my issue?
Thank you very much for any replies.

The black insert around the shaft needs to be removed. I think it is glued in, so it might ruin the body when removed as in the picture.

Thank you for your reply.
Probably the only solution is through a mini drill with a cutting disk to be rotated horizontally between the plastic ring and the top of the metal plate. This will cut horizontally the plastic ring but will not ruin the plate (or at least, would only scratch it on the top).
For the rest, about the black sphere at the top of the stick.
Is there anybody that can suggest/explain how to remove it without break or ruin itself?

If it is a plastic shafted TAC-2, the ball is glued on. If it is a chrome shafted one, it is screwed on with some glue in the threads.

Careful use of a heat gun will soften most glue enough to pull it apart. Some glues are very easily "unstuck" with very little heat.
I use this method quite often on everything from small plastic objects to furniture, (both wooden and synthetic), and even to remove the felt on shed roofs that's stuck down with bitumen!
The problem you have with that is not applying too much heat so it affects the plastic in a negative way!
If you attempt it, be careful in the application and just heat a small area starting at the edges a little at a time while lifting it up gently with a jewellers screwdriver or similar.
Once successful you can stick it down again when ready and no-one would ever see the difference.

Thank you for your replies and tips.
I will try with a heat gun, I do not see other solutions to avoid damages.
If someone ever used a heat gun on tac 2, could he suggest to me the points on which to heat to better weaken the glue and remove the sphere and the plate with the minimum risk?
Thank you once again.

Try with a hairdryer instead of a heat gun.. A heat gun will melt plastic at any setting.

I use a heat gun on plastic quite often, even on PLA 3D printed parts which has a low melting point.
Like I said, the point here is "be careful", if you have any old junk laying around it's best to practice on it for a while so you get a feel of what is too much heat.
A good plastic item to practice with is food containers, apply heat to the label and peel it off.
At first I used a paint stripping gun and they will melt plastic very easily if you don't watch out like Jope said.
These days I use one of these https://www.ebay.co.uk/itm/300W-Hot-...sAAOSw10Fd9M4o,
they're not as harsh as the paint stripper and work at a lower temperature, they're also more directional with the heat and don't spread it around so much so you can work on smaller areas.
Another thing you could try is hold it over a pan of boiling water, depending what glue is used that could be enough to loosen it up.

Hi,
Thank you for the clarifications.

@ptyerman
I have the same model of heat gun you linked on ebay. Just the same!
I will follow your tips hoping not to ruin the parts of the joystick...

Thank you all for the precious helps.
