Answers.Body: <p>I agree with HaydenStudios, it is impossible to disassemble completely NXT motor without breaking the orange axle hub. You can nonetheless half-open it enough to see what's happening inside (you need a Torx screwdriver - T10 size if I remember well - to open it.

Body: <p>I have a motor that prevents the program from running. It simply allows a few slow movements forward with stops in between. It seems very stiff to rotate manually. Any way I can repair this motor?</p>
