I took it to a mechanic today and cut inside that circle with a lathe (?! I think this is correct word).
Bearings look ok, one of the brushes wire is black/burned, the other is gold, I think that is my problem :) Will try to replace it tomorrow.
If anyone is curious how it looks...
Thanks for your replies.
I will look for more motor rewind shops tomorrow, the one I tried today told me to came with the motor opened :)
Maybe I should have mentioned that it stopped working when I first started the car at very low temperature, after it was under -15 Celsius, Mitsubishi...
I cannot find a new motor (part number was washed out) and the complete pump from Mitsubishi is between 1500-3500$.
I heard some people mention this happens when "start capacitor" of the motor is burned, that makes sense, but I don't know if this motor has a capacitor (maybe inside).

Hello.
I have a 12V motor from an oil pump, an AWD/4x4 differential oil pump, and I am unsure if it is burned or not.
I put power on it and it remains still unless I give it a turn by hand, then it starts and it appears to increase its speed slowly.
It has only ground and one pin, so two wires...
