The scroll wheel on this gaming mouse has holes in it that the optical sensor uses to detect when the wheel is turning. If dirt or other foreign material covers the sensor or the holes, the scroll wheel will stop working or may only work intermittently. This guide will demonstrate how to open the mouse and take the wheel assembly apart for cleaning.

  1. Use a thin blade to peel up the corners and remove the mouse feet. They re-adhere very well, so be careful to not damage them or get the sticky side dirty.

    • Unscrew the three screws that are now visible.

    • Gently pull apart the top and bottom halves of the mouse. They will be connected by a wire.

    • Take the scroll wheel assembly apart and clean off any obvious debris.

    • Look through each of the holes in the scroll wheel to check for debris that could be obstructing the optical sensor. Use a needle to clean out any obstructions.

    • Optional: If there is any material near the base of the mouse, under the scroll wheel, the sensor chip can be unscrewed and removed.

    • Use a gas duster to remove any remaining dust from inside the mouse.

    • Reassemble the scroll wheel.

    • If done correctly, the wheel should click while scrolling. The wheel should not spin freely.

    • Optional: Before reinserting the scroll wheel peg, apply lubricant if needed.

    • Slide the scroll wheel back down into its housing.

    • Make sure that the spring is aligned correctly.

    • Place the top half of the mouse back on to the bottom half and screw the mouse together.

    • Stick the mouse feet back on to their respective locations.

    Worked, wheel is working extra smooth. But the wheel is extra smooth, but there is no clicking sound that comes are regular steps. I feel like dropped some tiny spare part from the wheel-sensor assembly while taking it part. But I am not complaining! Thanks to the author who helped me get my favourite mouse back. This mouse is atleast 7 years old, and fit my hands very well. A new replacement with same dimensions and design features would cost me a great deal of money here in India.

Plug the mouse back in to a computer and test for responsiveness. If the mouse wheel is clean but still does not function, contact Logitech support.

My mouse went from scrolling just fine to nothing overnight. This helped a lot, but sadly its still not 100%. :(

Worked like a charm. Thanks. I really like this mouse and didn't want to have to get used to another one.

Fantastic!!! I've been really reluctant to replace my MX510 mouse -- your teardown of this one (which the internals appear to be identical anyway) was perfect!

My mouse is running like brand new again!

Immensely helpful, probably wouldn't have been able to put the mouse back together without this

Great guide! Scrolling was "skipping" on my MX518 after 7 years of use and these instructions helped me reassemble after I cleaned untold amounts of lint and debris from inside. Would have probably given up on the finicky scroll wheel mechanism and discarded a perfectly good mouse if not for this guide...

Same problem here, but i had to change a 150ohm Resistor as well (0805 package). As crazy as it sounds it was cracked and the wheel was completely dead, that's what happens with a +10 year old mouse i guess, all sorts of weird things can occur. Oh and you can salvage parts from certain older Logitech ball mice like micro-switches and wheel mechanism, internally it's the same design !

Thanks for your help. Here are some notes on cleaning the MX600 scroll wheel that differ from your instructions:

1. There are 4 pads and 4 screws - lift each the teflon pad and the double-sided tape that's underneath to reach the screws.

2. The scroll wheel design is quite different - best to remove the mounting screw near the front of the mouse to remove the wheel assembly.

3. The wheel can be popped out of the assembly with care - NOTE that the inner hub has a tiny SPRING LOADED BALL BEARING!!!

So open it over a clean space (I lost the ball bearing twice while trying to re-assemble it).

4. To re-assemble the wheel assembly, hold the hub so the ball is sitting on the spring at the very top and then tip and lower the wheel over it.

Really nice guide! got my partner in crime MX518 back operational for further scrolling work.

Thanks! Clear and easy instructions, and I was able to repair (ie clean) the insides of my mouse and now it scrolls again like new. Thank you!

Helpful guide. Clarity made it so simple for a beginner like me, and I believe everyone would agree on this. Thanks so much, I was able to fix the scroll wheel of my MX 518 mouse. And it's back on. Mercy!

Update: I have started facing a new problem on my MX 518. Buttons, and scroll wheel are working perfectly fine. However, the cursor does not move. LED light is off too. Any guidance to fix this issue would also be highly appreciated. Thank you! :)

Nice one Ben, I've been using my mouse for a few years on an Auto CAD workstation. brilliant thing but the scroll was playing around (used for zoom in and out) so I used this guide to clean it. I think I accidentally cleaned the underside so it's a bit quicker now and need to adjust, ha! Brilliant stuff, thank you very much.

I’m getting massive disconnections on the mouse and feel there is a cable connection issue but the cable from the USB port to the mouse is in perfect condition. I have to twist the cable at the mouth of the mouse to make it turn back on. It’s random. Can this guide help?

Hassan Gulzar - 返信

Great guide, thanks! My MX518 is about 7 years old and 5 of those are with a dog in the house. There was an unprecedented amount of lint and hair stuck around the wheel inside the mouse. Now my trusty old mouse will get a few more miles in the counter!

Just a heads up, the pads/skates on this MX518 had me very confused at first because they look like the G400/G400s skates.

My MX518 has different pads on it as shown here https://imgur.com/a/pn7uDTZ

That means the screws were easier to get at though!

I had the same cable issue as Hassan Gulzar, but managed to “fix” it by opening up the mouse and reseating the internal connector for the USB cable. I also gave it about 10mm more slack on the inside than it used to have, just so it doesn’t pull directly on the connector.

Now it seems to work as new again, the disconnect-when-moving issue is gone (for now) :)

You have an MX-518 v1, the one pictured in the guide is an MX-518 v2.

The MX500, MX510, MX518 v1, MX700, and MX900 share the same skates as each other.

The G400S, G400, and MX518 v2 share the same skates as each other.

(I’ve been thinking of getting a Hyperglide kit for my v2, but they make kits for both versions, so you have to make sure to get the right one.)

The cable thing is likely damage to the internal wires from repeated bending against the edge where they go in. Moving the cable in (to “give it slack”) probably put the damaged part inside the mouse where movement won’t flex it into a “bad” position. I’ve actually replaced the cable in my MX-518 twice over its life, using replacement cables bought cheap on eBay. I’m actually considering upgrading to a “paracord” cloth-covered cord sometime, which is definitely an option to keep in mind. (There are a number of people online who make and sell this type of mouse cord for a variety of mice.)
