Introduction: How to Make a Mousewheel Scroll Smoothly

Picture of How to Make a Mousewheel Scroll Smoothly

Because we are all tired of your scroll wheel clicking. This instructable will guide you through making your computer experience much better.

Step 1: Open Your Mouse

Picture of Open Your Mouse

Locate the screws on the bottom of your mouse and unscrew them. This will probably take a jewelers screwdriver, since they are pretty small screws. Pull up on the back of the mouse, and pull back. It is not necessary to force. There are tabs in this stock Dell one, that force you to pull back rather than immediately out.

Step 2: Remove Mouse Wheel Assembly

Simply pull up on the plastic assembly holding the mouse wheel, including all springs attached.

Step 3: Remove Spring

Remove the spring holding the mouse wheel on, and then remove the spring that is holding on to the mouse wheel. This spring is what you feel clicking when you scroll with the wheel. What it does is press against the inside of the scroll wheel and when it goes over the bumps on the inside, it compresses. It then snaps back producing that click you are getting rid of.

Step 4: Reassemble

Picture of Reassemble

Put the first spring back on, and put the scroll wheel assembly back onto the mouse's PCB. If you are testing without the case assembled, to not be alarmed if it does not work. The wheel works because of the IR sensor near it, and it depends on the spacing greatly.
Put the case back on and tighten all the screws.

You are now finished.

Thank you for helping me forward to this! you are such a great guy!

Hello Crash2108,

Thank you for this great article.

I've followed your instructions with a noisy mouse and the result is excellent.

A question with your permission:

The Logitech K120 mouse does not support horizontal scrolling. Tilting the wheel is middle-click.

The problem is I can only tilt it to the left. Is it possible to make it "tiltble" to the right?

I'd appreciate your help.

Best regards.

The mouse used in this instructable is a Dell mouse, apparently. For which other brands of mice does this work?

AaronL44 (author)2016-03-15

Not even sure why Dell felt the need to make their mouse so noisy, but thanks to you, now mine is quiet as a . . . mouse.

EthanA22 (author)2016-03-09

Thank You! This just made my normal old mouse a high-speed new mouse

MarvinL9 (author)2016-02-09

Thank you for the great article.

I just removed the spring accidentally when I was cleaning up a logitech M100r. So I searched about it and am leaded here. Good to know it's a proper mod.

RobertS238 (author)2016-02-08

Thank you so much for this. Just replaced a Dell mouse due to its noisy scroll wheel - could have saved some money if I had discovered this instructable sooner!

jafelds (author)2016-01-27

Thanks - this works great! Just a note on finding the case screws on a Dell mouse - they may be hidden under the bottom pad (the crescent-shaped sticker). This should restick after you have followed the instructions.

KellyB73 (author)2015-12-30

Soooooo. Happy!!! Took mouse apart to clean it, as it was double clicking by itself all the time. The springs came out before I could see how they went back in. The photos were all I needed.

I need to remove the springs from two co-workers' mouses as they scroll in unison and it drives me crazy. Our Lenovo mouse doesn't appear to have a screw on the bottom.

MichaelJ21 (author)2015-05-25

Thanks so much. I took my mouse apart to clean it, and the mouse wheel fell out. I must have spent half an hour trying to fit it back together, before I turned to Google. I had no idea that spring was only there for the click. Now the spring is gone, my mouse is back together, that annoying click is gone, and you've saved me hours of aggravation and maybe a new mouse. Thanks.

Thanks a lot for help...

jordi.maurell (author)2015-03-20

great guide to reassemble the spring! very useful, this unbreakeable mouse has returned to life, i wasn't able to mount it. Thanks a lot

darkalter2000 (author)2015-02-28

It seems I am going to continue the tradition of thanking you for your picture of your mouse's inner workings. I was having trouble with /both/ springs. Thank you for your assistance.

aldwin.ibuna (author)2015-01-28

Able to do it with a Logitech M100.. many thanks!!

GautamS2 (author)2014-12-25

Thanks you very much Bro!!! You really rock ........

I just now removed wheel click from a Logitech M557 Bluetooth mouse. First I removed the 2 screws in the battery compartment. Then I used a razor blade to pry up the far end of the 2 far pads so I could see the screws underneath (not necessary to completely remove the pads). I removed those 2 screws and then the top of the mouse was partially removed (wires still attached). The wheel ratchet spring was then bent away from the wheel. That was enough to remove clicks but I also cut and removed the spring. Very slick, I like it better than the Apple Magic Mouse for my Mac.

finder1 (author)2014-07-05

Many thanks to the author and comments, in addition to the 2 screws being found under the battery direction label, our Logitech wireless mouse had 2 more screws under the 2 front pads. The pads will have to be removed as well as the glue that holds them down. Once that is done and those screws removed, the 2 halves of the mouse will separate. You will need a small phillips head screwdriver to remove these screws. Then, taking a small pair of needle nose plyers, you can just bend the clicker wire out of the way and then reassemble the mouse. This solved the problem of not having smooth scrolling for this mouse using the HP Chromebook 14 using the Google Chrome browser. PERFECT!

Is there a way to make that small mouse button click-less or silent or use less effort for clicking ? Way useful in gaming scenario.

Crash2108 (author)maindoor2014-04-15

Depending on your mouse, bend the spring back slightly so it puts less pressure on whatever grooves are there to provide texture.

hhgygy (author)2014-04-06

I just signed up here to say a big thank you to the author, as I disassembled my mouse, the left tricky spring fell out and I had no clue how and where to put it back.

Absolutely great info, thanks again.

trevorcgross (author)2011-11-23

Thanks! makes me a lot less paranoid.

glcec1 (author)2011-09-14

Thank you!!!! This was the most helpful site Logitech couldn't even help me. It took me longer to find your site than to follow your instuctions to put my mouse back together. You are the best :)

PSPerson (author)2011-07-26

aahhhhhh. like butter. just wish ubuntu had a smooth scrolling mod now...

rgilman1 (author)2011-06-14

Mouse fell apart when I went to clean it. Pics helped get it back together right and working great. Thanks!

jcustard (author)2011-06-12

Very Helpful Pic needed it to figure out how left spring went back.


davidkichi (author)2011-04-22

Hey, thanks a lot! This great pic of the springs came very handy!

akmcnutt (author)2010-10-19

Thanks! This saved me time, money and headaches. Dropped the mouse and the left click button wasn't responding. When I took it apart to see if it was fixable, the springs fell out and I couldn't figure out how to get them back in. The freewheel function was too weird for me so I put both back but I could not have done it without these pics. The click button still isn't working great but at least it's useable.

sheneruk (author)2010-08-07

I had no hope of saving a mouse I attempted to 'clean up' after unscrewing the casing and watching the springs come off after turning it over. This instructable, and the fantastic picture of where those springs go, saved me some cash in not having to replace the mouse. I was seriously going to pitch the whole mess but waited until I had a chance to search the web. I couldn't believe I found this. GREAT INSTRUCTABLE!!

Kaiven (author)2010-07-25

Whoa, it feels weird without the click. It's good for silent browsing at night though xD I'll keep it with the mod.

thesparine (author)2007-05-08

Awesome! Thank you so much. This is so much nicer. Why did they even design it to click in the first place?

zeemvel (author)thesparine2010-03-24

If you're gaming, and one scrolling click means switching the weapon once. Two scroll clicks means switching two weapons further. And so on...

Junkyard John (author)thesparine2008-08-17

Two reasons, I think. One: really old mice probably had very low resolution optical encoders. Two: The snap prevents the mouse from stopping in between degrees in the encoder shaft (which still happens sometimes).

zeemvel (author)2010-03-24

Ok, so I had disassembled my logitech wheel mouse to clean it, only to find that I was left with two springs and didn't remember how to put them back.

Even though this article was about *removing* that spring, this article did the opposite for me and showed me how to *add* both springs again.

Thank you!

Spykerwolf (author)2010-03-22

awesome guide, just finished it on my Logitech mouse. No problems whatsoever.

Gamer917 (author)2009-03-03

my mouse doesnt click very loudly and im used to it

A.C.E. (author)Gamer9172009-06-19

then you obviously dont need this, and didnt need to wast your prescious time commenting. to the author, great ible. if my mouse has the same setup on the inside, im dont this. more precise stuff while zooming or using modeling programs, and it just plain feels better.

A.C.E. (author)A.C.E.2009-06-22

whups i meant to say doin this. i have lots of spelling mistakes for some reason.

hellstudios (author)A.C.E.2010-03-22

Then I'm surprised your name isn't misspelled, lol.

hellstudios (author)2010-03-22

I did this exact same thing when I was modding my mouse to make it all completely black and white. I was like "hmmm, I wonder what happens if i remove this spring" and then I was like "OMFG, I LOVE HAPPY ACCIDENTS."

Then i wrote a slideshow about it and wrote it off as if i meant to do it on purpose. Yus.

tanmanknex (author)2010-01-01

My mouse scroll wheel doesn't click at all. That's kind of weird, I wonder why...

test34 (author)2009-11-18

...but instead of removing that second spring, I bent it down a little so the wheel now barely clicks when I scroll yet still offer a little resistance so that it doesnt free-spins

test34 (author)2009-11-18

thanks for this howto, my wheel is now silent (unless I click)

Colonel88 (author)2009-09-10

Ye my mouse has like a three tabbed thingie holding the mouse wheel :O
