[* black] Lens disassembly and reassembly is much harder and I haven't yet fully mastered it. However, you can test the operation of the lens mechanism as follows. (Do this after reassembly if you strip it down.)
-[* black] Gently lift the ribbon cable connections off the 2 tags on the back of the motor.
-[* black] Apply power to the motor from a 3v battery pack by connecting it to the 2 tags on the motor. Reverse the polarity of the battery to reverse the direction of the motor, according to whether you want to extend or retract the lens. (Keep all ribbons out of the way - applying power inadvertently to the wrong place could damage something.)

Apply positive to the terminal to the front of the lens to extend it, or to the back of the lens to retract.
