So I have been doing this modifications too all my mouses for at couple of years now.
Not because the silencing effect but because the feel the mouse gets That it gets more silent is just a bonus!

The whole thing is VERY easy and takes about 5 minutes, tops

The basics is open the mouse, remove the pin on the scroll wheel and close her up again. DONE.

What you get is a SMOOTH scroll wheel without the stops and the loud sound those stops do.
Some people thinks it feels weird in the beginning (and maybe it does if you not use to it) but after a while you grow to really appreciate the smoothness.

And heres the Picture guide! :

Get your mouse! (I have only done this on Logitech mouses but my guess is that all scrolls are the same)


Remove the hood, the batteries and the screws (some mouses you work from the top, like this one. And some from the back.)


Separate the top from the back. (usually a cable in there you have to unplug if its a wireless mouse).


This is what a naked mouse looks like:


Remove the scroll wheel. Usually just lift it straight up.


The wheel usually has two metal pins. One on the right side and one on the left. Witch to remove tends to differ from model to model.
But it is the one that goes IN to the wheel that should be removed. The other one is used as a spring so that the wheel will also work as a button.


Then put the scroll wheel back in the mouse as i where before (without the removed pin).


See to it that the other pin is seated correctly, otherwise your scroll wheel will not as it should. (just open up and replace it if it doesn't).


Plug the cable back in and put the top back on. Screw in the screws.


And finally put in batteries and the hood again. And you're done!


And if you use Firefox i recommend "Yet another smooth scrolling Add-on"

Thank you for listening

very nice and simple!

did it just now, it feels really weird but i like it already - not to sure how its going to affect gaming though.
(using a logitech mx518 btw)

Lol. I actually like the "bumpy" feel.

Of course, the easy way is to get one of those Microsoft mice that come have "smooth" scroll already.

Oh thats good.

Feels great on my MX500.

The thing is not all scroll wheels are the same, so you might improvise, depending on the mouse model.

Ok, that i probably true. I have only done this on a couple of logitechs and they all where the same.

But i would guess that the difference cant be too big.
If anyone has pictures of other mouses you are welcome to post them here

Very nice, simple, yet effective mod. Thanks for sharing it with us!

yup i did this exact same trick on my logitech mouseman optical some years ago i like it too, there was only one issue which is that since the mousewheel can stop at any position (when previously it would only 'land' between bumps) it can sometimes stop right at the edge of a 'tick' if you know what i mean. then the window sometimes will scroll up and down suddenly with the slightest bump. not such a big deal, but in games sometimes it makes you switch weapons unexpectedly, and you will get killed during the weapon switch animation

i hadn't seen that fx plugin before though, i just installed it then it's quite nice!

I did this accidentally when I opened my Logitech MX500. That spring just fell out when I opened the mouse casing and I didn't find the place it came from, so when I put everything else back together, I got a smooth mouse wheel, and liked it.

The reason why I did pop the mouse open was to remove the weight. In a MX500, there's a small piece of metal screwed under the top of the mouse, that has no other purpose than to add weight to the mouse. I like my mice light, so I removed it. Takes a bit over 10% off the mouse weight altogether.

Awesome scrolling plugin, thanks! And it even works with Firefox 3.0 on Ubuntu/Linux.

i've found the apple mighty mouse to have the quietest scroll ball i've ever used, mainly because the clicking sound is actually generated by a speaker...if you break open your mighty mouse, you can actually muffle it to nothing...but it has a very nice sound to it.

Brilliant, just brilliant, did this mod to my mice straight away, wow...finally...silencium !

This one is well worth a sticky, heck, it should be a sticky.


Thanks for sharing Rackafella

dubble post

the logitech VX revolution has a cool little switch that changes the scroll wheel from the bumpy mode to smooth scrolling. pretty cool.....

nice post...

I was too lazy to try so I bought myself a VX nano... silent scrolling

good work

Unfortunately, this doesn't work on Razer mice. At least, not on my Krait.

hey mouses are supposed to make click-click

I have Logitech trackman wheel, the wheel looks identical to yours. I took it apart to clean, couldn't figure out how the spring goes back. The spring on one side makes all the click-click as you turn the wheel, the other one helps it bob up & down,,, gawd I'll never open another mouse again...

Hey!
If you take a look at this picture you can see how it shuld be:



The "rounded" end of the spring goes, inside the wheel and the square end goes in the plasic "foot".
Easy

If its the other spring its even simpler, just look at this picture:

its kind of self explanatory(?) i think
/r

this got a sticky? awsome

Great guide!

Also note, the Logitech LX5 mice now have a spring + ball bearing that produces the clicking noise. If you wanted to quiet down the "clicking", you could either relieve some of the pressure from the spring steel, or sand down some of the plastic ridges inside the wheel. If you want to eliminate it completely, simply remove the tiny spring and ball bearing.

If you want, I can sacrifice an LX5 mouse to inspect the momentary switches for the Left/Right buttons as well.

I'll snap a pic later and edit this message. Will also post pics of my Microsoft Intellimouse Explorer.

I did that by accident to my MX510 when the right mouse button broke and I tried to fix it (lost the pin)


Yes, it's silent, but now it has no feeling :/

Unfortunately not possible with the Microsoft Optical Trackball, that just has teeth on the rotating shaft. would be possible if you were to brake the two pieces of plastic against the teeth but irreversible and wheel would more than likely spin too freely

I have some random razer mouse. It has by default a silent scroll, heh.
...Still sounds when pressing the LMB and RMB, of course.

I just did the mod on my elcheapo Logitech wired PS2 mouse. Exact same innards. WOW

It would be nice if we could silence those LMB and RMB too! Anyone know how to silence a keyboard?

acoustipack?

If your LX5 is still alive please do post the pics I want to know how I can disassemble my Lx5. I removed all screws and then the back lifts easily but the front is somehow sticking and won\t open. I damaged & broke a LX5 like that, but got out of the story by setting the 2-pin wire reversed and then put some batteries wait till the mouse got hot, removed the batteries and took it to the local PC store and said the mouse "fell off" my desk and got broken. I got a new Lx5 Now I want to dot it correctly though

try looking for screws under labels or rubber pads

try to have put some oil
