Disassembling Logitech MBJ58 Mouse Scroll wheel from mount

Hold the mouse in your hand so that the bottom side is facing upward.

Locate the #1 screw towards the bottom half of the mouse.

Take the 4.76 mm Phillips screwdriver and unscrew the #1 screw that was previously located.

Place the mouse back on the hard surface, with the bottom side touching the hard surface.

Gently, lift up the top cover of the mouse and remove.

Locate the scroll wheel on the mouse.

Grab the scroll wheel with your thumb and index finger.

Gently lift up to remove the scroll wheel from the mouse.

Locate the spring on the scroll wheel. The spring looks like a small, metal piece of wire, coiled up in the middle.

Very carefully, remove the spring from the wheel scroll.

Replace the spring making sure it is placed on the right side of the wheel with the prongs pointing down.

Be aware of where the resistance spring is.

• This spring will easily fall off.

Grab the scroll wheel and its mount and gently pull them apart.
