Hubmotor disassembly?

I'm hearing a scratching noise from the my hub motor of my Erider Puma and was thinking about opening upp the motor to have a look.
Has anyone done this?
I guess I'll need some kind of gear puller or something to overcome the magnetic force when pulling out the rotor from the stator?

Puma: Change rear shock oil

My Puma rear shocks are not very smooth. When I compress them, it feels like a jumping movement, not smooth.
I'm going to try and change oil, but I don't really know how to open them up.
Any advice?

Opening up the 5000Li Controller

Has anyone on "V" opened up the Controller on a 5000Li Moped? The reason I ask is that I am without lights on my 5000Li. I have a good DC and we have tested the wires from the DC to the Controller and there is no power coming out. I have power to the motor and the battery pack is fine. I just don't have lights and I have no experience with the controllers to just open one up.

Anyone parting out a XM-5000Li

I am checking the waters here to see if anyone is parting out their XM-5000Li. I have +28K miles on mine and I would like to keep going. If you have a working charger, please let me know.

Vibrations

Since this seems to be a common problem, I'll make a separate thread about the issue.
There seems to be a couple of possible sources of vibrations,

- Unbalanced front wheel
Easy to fix with normal balancing procedures.

- Unbalanced rear wheel
Harder to fix. Any ideas here?
Putting magnets on different positions and spinning the rear wheel with the motor on the center stand might work, but seems a bit arbitrary.

- Tyre is not symmetrical
Seems to be common with the standard Chinese tyre.
Throw away and buy a new one.
