  <p>This motor does not work well. After pull back it moves forwards 2 and a half wheel turns and stops. There is a small resistance forcing it forward two millimeters it makes a louder click and then the wheels rotate again 2 and a half turns to stop again. After forcing 2 mm it continues again and again until the spring is loose.</p>
  
  <p>As there are no screws to open it and fix the mechanism I don't know how to open and fix it.</p>
  
  <p>Can anyone give a tutorial to open it non destructive and fix it?</p>
