Lewm: "When I look at the two photos, I do not see where the chassis can be separated from the stators of the motor."
I don't own a Mk3 so all I can go by are the photos and judging by the pictures I don't see the motor as that much different from the Mk2, which I took apart many times, in terms of assembly. Looks like you can unscrew the four hex screws with the arrows to remove the motor. I am not a machinist but I don't see taking the motor out being that complicated... maybe very time consuming, but then again I don't own a Mk3 so I really don't know. The Mk3 is maybe too belabored for this kind of project. I recommend the MK2 motor, or JVC, Kenwood, or Pioneer motors.
