How to Disassemble a Logitech Trackball


Logitech is known for its line of wireless and corded trackball computer mice. The trackball refers to the ball housed inside the socket of the mouse. The ball contains sensors that allow the device to detect rotation and any form of movement. When the user rolls the ball using his fingers or palm, the computer screen's cursor will begin to move. The Logitech trackball mouse needs to be cleaned regularly to avoid the buildup of dust and dirt. To perform the cleanup, you must disassemble the trackball completely.

Things You'll Need

  • Small screwdriver
  • Shut down the PC and unplug the mouse.

  • Remove the trackball from its plastic housing unit. The holding units are available in two types. One with a retaining ring and one without. Take off the retaining ring by turning it counterclockwise, if applicable.

  • Tap the back of the mouse gently to allow the trackball to fall out in your hand. Avoid popping the small Teflon balls out of the mouse.

  • Use your screwdriver to unscrew the tiny screws found at the bottom part of the mouse. The screws usually are attached to the cover of the trackball. For trackballs where there are no screws holding them in place, you can remove the plastic covering from over the mouse.

  • Unscrew any additional screws that are holding the trackball in its place with a screwdriver to completely disassemble the Logitech trackball.

Tips & Warnings

  • Clean the Logitech trackball monthly to keep dirt from building up. Use a toothpick or a cotton swab to remove the grime or debris from the trackball socket. Use isopropyl rubbing alcohol on a cotton swab to aid in loosening the grime.
