Maybe someone will advise me because I have no idea. On YouTube, the guy after unscrewing easily pulled out the rotor at this stage, and for me it is not possible.
If you can't pull the rotor out, as colleagues have said before, you have an overheated stator.
I assume you have a vise.
Hold the grinder firmly by the aluminum head so that you can hit the plastic body with the hammer. So you have it in a vice. You twist the body slightly so that you have a pounding edge and bang with a hammer through e.g. a wood.
You have to watch if the wires do not strain when knocking out. If the stator is badly welded, you will have to disconnect all cables from the electronics and brush holders so that the rotor comes out of the body together with the stator.
Of course, the nut on the rotor is unscrewed with a wrench, not an impact wrench.
If you do not damage the magnet, you do not need to replace it after each disassembly. It is pulled off together with the placenta.
The bearing in the bearing flange is not replaceable (encapsulated in plastic). It is replaced in full. You need at least a hand press to pull the wheel.
In general, don't go without it without the press.
