Introduction

The spring in the Logitech MBJ58 Mouse may wear down over time making it hard to scroll smoothly with consistent notches. This may require an easy replacement of the spring to return the mouse to normal functionality. This guide will help you learn how to remove and install the resistance spring of your mouse.

    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.

    • Insert the hooked section of the replacement spring into the corresponding hole on the mount.

    Thank you, thank you, THANK YOU! Worked for Click! Cordless Optical too. I had taken the mouse cover off for cleaning. It was a mess inside. Lifting the wheel out, those two springs fell off. I had no clear idea how to re-assemble them... until you. How much do I owe you? I'd gladly pay.

This mouse was also available from Dell as an OEM device under the model name "M-UVDEL1". Hopefully the Google juice will help folks repair their devices. I know I would have spent far more time than I did if it weren't for the photos on how to put the spring back. Thanks Maximilian!

The spring installation details were lifesavers. Thank you!

Brilliant. Thanks. Easy once you know how. The springs were the hard part.

Charles Thomson -

Thank you so much!! You made it very easy and quick!

Used this to figure out how to return the support spring to the correct position for a model M-BJ67B.

THANKS!!

Do you have a part number for the resistance spring? I dropped mine and can’t find a new one on the Internet anywhere.

Aidan Franits -

The spring fell out when I took mine apart (without reading these instructions) your guide was amazingly useful and clear for me to successfully put it back together. Thank you

Jom Bom -

Also works for Lenovo M-UAE119

Where can you buy a replacement spring for the click part? My boyfriend dropped it on the ground while trying to examine it and it's so tiny it disappeared, he really likes this mouse so he doesn't want to just buy a new one. Does anyone sell the individual tiny springs under the click part of the mouse?
