Introduction

This guide shows how to disassemble and remove the scroll wheel of the Logitech MBJ58 optical scroll mouse. This might be necessary if the wheel is stuck, difficult to turn, or dislodged. If it becomes dislodged, it can cause additional damage to the mouse’s motherboard, which is located beneath the wheel.

The scroll wheel may become jammed if the support spring that holds it in place is dislodged. To see how to repair that, as well as how to deconstruct other parts of the mouse, see the Logitech MBJ58 mouse troubleshooting guide.

    The cover doesn’t lift straight up on my model - once you raise the back slightly as shown, gently pull it backward (parallel to the table top, away from the cord) to disengage two plastic clips that connect the bottom to the top.

Excellent! I took an MBJ58 apart to remove accumulated gunk, and the resistance spring jumped onto my worktable before I noticed where it came from. Thanks for the help, well done!
