Logitech G502 Disassembly & cleaning

- เผยแพร่เมื่อ 14 มิ.ย. 2021
- Bought both a normal Logitech G502 and a G502 Hero mice and they were in need of some cleaning before they could be used so I recorded how to clean Logitech G502 and its hero variant them and what went wrong. If you want to do this yourself, do buy a set of new teflon pads for the bottom as its more than likely that you can't use the old ones

My biggest problem with this mouse was the rubber gripping around the mouse in the back and on the side. When attempting to spudge the thing open, the rubber would just break away as if it was clay. Still, that is mostly a cosmetic problem and this mouse has been excellent for me over the years. I just have the issue where my mouse will randomly scroll up or down for seemingly no reason. Used your guide to pop it open and clean it, and now it seems to work well again. Thanks!
That isn't so bad, it gets disgusting with age and use too.
Where can I buy the pads? What brand!
@@randymarsh9488 did u find where to buy the pads
@@theblackbro69 yes amazon called superglide glass skates for Logitech g502. last wayyy longer than rubber
@@randymarsh9488oh thanks bro
Thanks a lot man! You're a great technician and now the double clicking problem on the left button is fixed! Just gained a new subscriber!
Great video - thanks so much for posting! A little extra intel after I soldered in a new left button microswitch: the two microsprings go under the clear plastic spinner mount - you can see two little wells where they settle into. This gives the wheel a bit of spring. Magical!
THIS is the video i was looking for, not that other cotton swab "sweep the dirt under the rug" crap. the DEEP clean 😤😤😤
Thank you for this video! I have a G502 where the mouse wheel wasn't free spinning very well (would come to a stop shortly after flicking it). This video helped me take it apart enough to find lint/stuff wedged in the bottom of the clear plastic housing the mouse wheel sits in. Pried one side of it apart with a small screwdriver while carefully shoving a small strip of paper towel (cut with a scissors to size) soaked with isopropyl in there to grab it and pull it out. Now that thing spins like brand new AND the mouse still works!
Tip: Use this video to identify where the screw holes are in the skates under the mouse. Use an X-acto knife or similar sharp (but small) blade to poke INTO the screw holes, then carefully cut the skate material away (in a circle) running the blade at a slight angle to the screw hole. You'll get access to the screws without having to remove the entire skate or needing to replace them. The missing skate material (small circles) over each screw hole shouldn't affect glide. At least I couldn't tell a difference when I was done. Oh, DO NOT stab into the center one in-line with the cord. Heh, I made that mistake watching this at first thinking there was a screw hole. Luckily I didn't cut into the mouse cord in there.
Had the exact same issue, after 5 years it just stopped wanting to spin. I tried using canned air along the edge of the wheel to get inside but it would only last for a day lol. There was a bunch of gunk up in the clear plastic well of my mouse as well. Kind of reminds me of the gunk that got clumped up on the old ball mice.
Thank you! Spilled some coffee on my mouse and my thumb button got stuck. Cleaned it off, confirmed it was clicky again, and put it back together. Cheers!
Thanks for the tutorial friend, I had a problem with my Logitech G502 was not working well the cursor was moving like crazy. After opening it and cleaning it was solved.
Nice tut but I have a G502 wireless which has a few additional steps which I could not move forward on until I understand the mechanism, it's a flat cable being held firmly onto PCB's there's 2 of them and they are not like your typical phone connectors. To make it more difficult there is some sticky film on the actual joints. But I did manage to get the mouse working for now so I best get another cheaper one because you will never use the dpi on high
Thanks. After tossing a glass of water over my G502 yesterday I dryed it with tissues for some hours. Later that evening I used it again and the mouse wheel was buggy. It went away, so I thought it is fine. Today one of the extra buttons was permanently pressed and then it was broken completely. I hammered it for like 100 times.
Then I decided to clean it following your guide, which I finished 10 minutes ago. Before I put it back together I tested if the switch is still working and it was. With that in mind I put it back together after getting some hairs and a small feather out of it and boom it is working fine again.
Great!
a small feather?!?!? vot di fuk?! how farking zmall feather is getting to mouse?! you release a wild bird in the computer or something you fkning crazy jeet-pun rajata rotta!!!!!!!! boburk!? :O :O !! HO!
this is an excellent video, I was able to get off just putting the stickers back on but I already ordered new ones, special thank you for the info on the small springs I couldn't remember where they were before 🙃
thank you so much!! I had spilled a sugary drink not long ago on my mouse, and its only been getting worst - sticky inside. it was frustrating because theyre all my main buttons! Now after a huge clean, everything works like brand new :) And it feels clean lol!
Cleaning just the top shell fixed my left button not being able to drag and copy. Thank you
my logitech g502 hero was dead, even the lights didnt turn on when i pluged in the USB cabel. Now its working like its new.
Thank you for the tutorial. ( you forgot the springs for wheel, and its hard to see if you put the transparent plastic piece upside down or not)
This mouse has pads that are kinda hard to reuse but I was able to reuse them by using a weak glue (will be easier next time).
Also, unless I need impact resistance, it doesn't need all the screws, so I refrained from reattaching the screw under the tinny pad.
The other pads can be just minimally opened just enough to reach the screw. That's how I did with the other pads.
They always come off sooner or later. I also wish they didn't use rubber that turns disgusting with age. If you ever had tools with rubber on the grips, it is the same stuff. There must be something longer lasting they could use!!
@@charleshines8523 Indeed. Also, rubber grips. I'd just use hard plastic pads. Also, for the screws... Just put 3 behind the removal magnetic pad! Why putting behind the glued parts?!?!? 🤦
My 5-year-old G502 has an ocasionally stuck wheel and I tried to open it, but the screws just won't budge.Not sure if I'm using improper tools or if something's wrong with the mouse.
my sniper button on the side broke, im quite happy that is is just a $8 part and i dont need to solder anything. thanks for the tutorial
Good video,
Sadly I failed at removing the husk, didnt want to pry it even more in fear of breaking something.
But I managed to clean the scroll wheel decently enough for it to spin smoothly again.
thank's for the guide, had to do the same. Just small hint- springs, booth of them, comes under the weel in to the holes next to golden 3rd weel button. 9:34 above hand You can still see them in places. Booth sides of the weel button.
Who needs to put the springs back in, pshhh. @15:36
Well, this helped me take the mouse apart and confirm that the left click switch is actually bad, not just dirty. It seems after 5 years, either the little Omron switch or the "pad" on the left click button that contacts the switch has worn down enough to remain flaky. It seems like placing a thin layer of a durable material over either surface would solve the problem. But I worry about it wearing or producing dust that would interfere.
you can certainly do that, I would just swap the switch.
Honestly if you bought it second hand I would have cleaned the outershell only. No need for taking it apart. But very comprehensive video. Great work.
thanks for this amazing video
was gonna buy a new mouse and then i saw this video 🥺 saved me 70$
Fantastic video. Mine was full of grimey gunk.
The spring is for the mouse wheel click.
Thanks. Was able to fix my wheel ratchet button
Its much easier to take of slider pads if u heat up glue witha hairdryer
what a well designed mouse!
It was much better when Logitech used the clickers from japan, they use the chinese ones. My G500 lasted 12 years before one of the clickers went out--my G502 hero is less than 3 years old and I'm already having right click issues... I also never cleaned my 502, the gaps were smaller and there were less issues with "gumming" than the 502. Sadly I gave it to a friend...the G500 is better than the 5.2 for my tiny hands.
Thank you for this excellent video! I was able to disassemble and clean my original G502 from august of 2015, after the scroll wheel got gummed up. I was blown away by how much gunk had collected inside the scroll wheel area.
I want to do this cause my mouse has torouble holding left mouse and it really fucks me up but this just seems to much. I would probably end up breaking it before anything
yo my programmable mouse button just fell of but it doesnt seem to break or anything it just fell of so should i glue it or what
What if i want The smooth pads?
can i ues hair dryer to remove the glued bottom part ?
thank you so much i could not get mine back together
Finally the hair that has been stuck under the sensor is finally done xD the only thing i've mostly messed up is the smallest pad (i've started by it to see how it was) and struggled a but for separating the shell but everything else was fine!
Guy must have the cleanest teeth known to man, with that brushing speed.
thanks.. going to rebuild mine now.. what screw driver kit are you using looks really good
its the old iFixit kit, they have a new better one these days.
I fix the middle button (wheel button: the tiny layer opf metal that bump) I cut the orange membrane e make it pump again. I really dont understand why is the only shitty switch inside
Does anyone here know how to remove the mouse wheel? Mine doesn’t have the color on it anymore and you can see the copper plus it corroded pretty badly so I have to repaint it.
I give you some good advice friends, you can make a small hole in the sticker that goes underneath the mouse, so that the next time you open it to clean, it will be MUCH EASIER and you won't have to spend extra money on those stickers!
My g502 got some wine inside, the mouse still working but a bit drunk ..sometimes it doble clicks when I press one click and it feels weird is very annoying ... I was thinking to open up but it is worth it to try?
most likely its fixable, might need to change on the the microswitches to a new one.
There is visable space on side of every pad clearly made to make taking off those pads much easier, you can even use fingers, but ofcourse it is better to do with something else
I didn't get what you were saying can u explain please
@@theblackbro69 If you take a closer look, around your pad, there is small fragment that allows you to dig under your pad much easier. Unless it is really dirty.
You can even see it on this video around 1:34, there is like darker fragment around pad he is trying to peel off. Don't try doing it from corners, start at that little spot.
@@dawidfrankiewicz8994 oh thanks i just noticed
@@dawidfrankiewicz8994 this was really helpful i always thought that part was broken
@@theblackbro69 I still had to buy new pads, even on that spot you have to be careful not to destroy pads. But new pads gives mouse a new life, especially after few years of use. Glides like D inside wet 18
Hey man, for cleaning the mouse wheel, could I use anything else instead of an ultrasonic cleaner? I'm guessing I can't just water and soap them , but could I use isopropyl alcohol and maybe some toothpicks/cotton swabs?
of course you can, anything to get the cleaning agent to move around in the assembly, ultrasonic cleaner is just a easy and lazy way to do the same thing.
@@Purkkaviritys thanks man
Dang my rmb switch was cracked. Idk how that could’ve happened. Might’ve come from an old fall and just got progressively worse.
Can someone please help me? My logitech G502 causes over current on my computer how can i fix it?
helped me a lot
Hey, I followed all the steps, connected the mouse to the usb port again and it seems like it's not connecting properly and I constantly hear the windows sound of unplugged usb ports. Any idea of what I did wrong? Thanks in advance
sounds like issues with the usb cable, the cable itself could be either poorly attached or have breaks in it, you can try to move the cable around in different knots to see if that causes the mouse to get usb signal, if it does you know you will need to change the cable. at 11:35 you can see me removing the usb connector, that might also be loose, so check the connection.
im using hot air at 120C to remove the mouse skates.
Thanks a lot!
so the rubber on the thumb rest has split. i.e bent upwards from the base and holding on by ~4 mm near the aim button.
Any advice oh now to glue this rubber part back together to put it in a usable state?
The rubber on this thing is very brittle.
Cheers
So this was my own fault as I was too eager to open the thing before carefully watching the video :P
You can buy replacement shells for £20 but would you say a bit of carefully applied 2-part epoxy glue would do the trick?
it can do the trick, but I would just get a new shell.
You forgot to put back 3 springs that come with the mouse. 1st two are under scroll click, and idk about 3rd but there is one :)
Thanks mate I did open and replace the left and right switch, now my mouse wheel does not scroll locked or unlocked any idea? Would it be the mouse wheel sensor?
yes, they are on the right and left side of the wheel inside, and they work by counting the number of times the spokes of the wheel cut light and bring it back again (wheel sensor led light and a light sensor), so if there is debris in the wheel they tend to stop working until the wheel spokes have been cleaned.
@@PurkkaviritysThanks mate your the answer , I cleaned as I could .The scroll wheel was not free spinning before the cleaning, but was working. Now cleaned does not work, the scrolling.
Super nice video, thanks ! I will order new pad though before i open it. My right mousebutton isnt working that good anymore, in shooter games i cant keep my scope, sometimes i cant even scope at all :( *mesad* hope i can fix it. If you have any advice other than cleaning let me know :)
sometimes the pats that push the microswitch can become worn so that they no longer press the switch and there is a possibility that the microswitch itself is dying, but thats all easy to test once you have the mouse open, just attach it to a compute nad press the buttons to see if they work or if its just the dirt and grime causing issues.
Great video.
I have the G502 hero but my right click is starting to get dodgy... I'd like to think it's because it's dirty but deep down i know it's because Logitech switched from the japinese to the chinese clickers.
my right click is bugging out to when ads in a game it has a spasm
I cannot get it open. This is impossible. So frustrating.
You forgot to install back two springs under weel )
LMAO
I saw that too
maybe I didn't follow close enough, where should I put the small springs back into?
you can see where they go at 24:18
@@Purkkaviritys thanks a lot mate!
thanks much, perfect guide
Where can I buy the pads replacement? What brand do you recommend?
in my experience, the quality seems to be the same regardless of which brand you get, you should be able to find them on both amazon and aliexpress
cool video
I have a question, if you want to clean the g502 mouse buttons inside, can you take apart them?
if the buttons don't work, need to be swapped for new ones, that involves desoldering them and resoldering in a new one to replace them.
@@Purkkaviritys ok thanks
I can't take out the top two screws. I have a Protheus Spectrum. Unlike the bottom screws, the top screws apparently don't have the + shape, all I can see is a dot in the center... what to do?
Check Google for 'types of screw heads' to see if there is something they you can identify as the head bring used, but it's weird as g502 should only use Phillips heads in all of the screws
@@Purkkaviritys I really wasn't able to remove the top screws. It was weird because I had never opened the G502 it and I bought it brand new. Maybe it was a batch that came like that unfortunatelly. I had to do some trick with a clip, a piece of thin cloth and some alcohol to be able to get the scroll to work again as dirt was blocking the light of the rotation mechanism. I also had to purchase new skates as it had the same problem as in your video. It's almost 6 years old mouse still working nicely except by the scroll which got dirt. I think the older the mouse gets, the harder is to remove the skates without damaging them.
I have a question, I have a similar mouse, and the click function has been damaged when pressing the mouse wheel, I have disassembled it and I see that the gold sensor that does that function does not click anymore, what can I do?
the gold sensor is just a dome type microswitch, they can be replaced by desoldering the old one and soldering in a new one.
If you have experience with microsoldering, you can replace it. If not, buy a new mouse... and use the old one to practice microsoldering. :)
What is the metal wash bin called and where can I get one? Is it just used for plastics? Thank you in advance.
It's an ultrasonic cleaner, its commonly used for jewelry cleaning etc. it vibrates the water to get the gunk to detach. you can was pretty much anything in it with the notable exception of MEMS devices
@@Purkkaviritys Thank you for the quick response.. Also, your video has been very helpful. Short, simple & to the point. I appreciate that.
Can you share a link with your entire toolset please?
While not exactly the same, all of the tools I use in this video can be found in the iFixit 'Pro Tech Toolkit', the gloves I use are just normal single use nitrile gloves.
Where did you buy the replacement feet?
you can find them in bigger computer stores like newegg, microcenter and other places like amazon, ebay and aliexpress. Mine at the time of speaking were from aliexpress.
If your going to clean your g502 I dont recommend re-using your original rubber skates and spending the 20 dollars for a glass pair off Amazon
so, I have a g502 and disassembled it to fix an issue with the scroll wheel toggle. I put the two springs back where they were. I somehow ended up with a third spring and have no idea what it's for. Any thoughts?
if it is a spring that looks like V its probably from the scroll wheel itself
@@Purkkaviritys it looks identical to the two in the front 😅 everything is working at the moment so I'll just stick it in a drawer and hope for the best
@@kimfink5060 must've been a shipping spring 😅
@@kimfink5060 same thing happened to me... i took mine apart even further but it doesnt seem to serve any purpose
i somehow ended up with 10 screws and i only removed 9. nothing seems to be out of place in the entire mouse.
Oh man. My right click functionality in my G502 Hero seems to be going bad. I'll be aiming down sights in games, and it will inconsistently drop to hipfire, then come back to the sights. I was wondering if a good cleaning could fix this. But seeing how I'll probably need new skates is making me think I should just get a new mouse since cleaning probably won't guarantee restored right click function.
its likely that the microswitch is worn down and needs to be changed, pretty easy fixing job if you have a soldering iron and a solder pump and even the pump is optional, just makes it easier.
See my M720 microswitch repair to see how its done.
I had the same issue as you. Using toggle zoom in game can be a temporary fix while you decide what to do.
For me I removed the skates and took of the lid of the mouse, then i just brushed away any easy to reach dirt and dust. I haven't put the skates on but you can either buy new ones online or if you have a soft mouse pad then the skates aren't realy needed. I did this about 6 months ago and the issue hasn't returned
I was having the exact same problem but on the left button, after a good cleanup it was working just fine! So you should definitely give it a try
While taking it apart, was there any clear indication, what makes this mouse so heavy and is there something to be done about it?
in the bottom, there is the panel that goes around the optical sensor, if you remove it there is a space for the weights, you might want to take that off and check if the weights are in, if not the weight just comes mainly from the plastic parts.
I think alot of people buy the g502 for the weight
I ruined 1 of 3 stickers so a partial success lol
And there was a chunk of cat hair stuck in front of the wheel
Voiko noita vasemmalla olevia alempia sivupainikkeita puhdistaa millään ilman että purkaa koko höskän? Mulla lens kokikset uuden hiiren päälle ja nyt ne jumittaa ja jää alas-asentoon... Ja vitutus on valtava :D
Suosittelen tilaamaan vaan ihan suoraan uudet teflon lätkät pohjaan ja avaamaan sen täyspesua varten, kokis on sen veraan kivaa ainetta et se ois ihan syytä pestä pois sieltä, sitä et saa mitenkään nätisti siivottua ulkopuolelta.
Kannattaa myös vähä lämmitää hiustenkuivaajalla niitä teflon tassuja enne ku lähtee repimään ni irtoo mukavammin.
Instead of peeling off the bottom pads, would it be better to just cut/drill holes in those pads where the holes are. Then we can just use the screwdriver through the holes. Of course, afterwards, those holes would collect dirt, but at least the pads would retain their original glue to the mouse.
that is a terrible idea, not only would it be difficult to do, the drilling would likely remove the pads anyway and you would likely damage the mouse, and considering that replacements cost like $5 its not worth it.
@@Purkkaviritys Well, I did it and it worked. I did not put the drill bit on a drill, just spun the bit by hand. Made a small hole the screwdriver goes through and undoes the screws without pulling the screws out of the holes. Bonus, the screws don't get lost because they can't fall out.
@@normcfu I agree, removing pads renders them useless
I put the springs back in but the scroll doesn’t click !! Need help
if you mean that there is no clicking when you scroll? in that case its not about the spring at all its about wether the scroll wheel is set to frictionless or indented mode,
If you mean that you can't use middle mouse click, that means the scroll whell assembly is not positioned correctly as it will click even without the springs, the springs just help it return back up.
@@Purkkaviritys Regardless of all this, is it okay if i didn’t put the springs ?
@@lilHrag maybe, maybe not, based on the amount of mice I've disassembled and how many of them have them, they probably have a good reason to be there as otherwise the manufacturers would have gotten rid of the little finicky parts they are to save costs.
I fix the same problem, is the metal membrane that make the click, sometimes it stay pressed without release, try to heat it or cut the membrane, make it "pop" and plug it in again (really hard job but it work for me)
Can't believe I just ordered a scroll wheel for a mouse.
i have a brand new g502 fresh out the box and im watching this for some reason, i just dont know why
time to order those skates as there will come a time when you need or at least should clean the mouse
@@Purkkaviritys surely! they're on their way to me sooner or later, I'll only put them on if i dont like the feel of the stock skates.
My left click some times clicks more than once and I often can’t hold a click+drag for very long (less than a second)
Gonna take it apart and see what’s up, but I fear it’s just too old :^(
Wish me luck
you can just swap the broken microswitch with a soldering iron. because that is likely the only thing that is broken.
@@Purkkaviritys I trust you but we’ll see. I’ve blasted air in there twice now and it’s been fixed for an hour or so after each time. Just last night I smacked it hard and it hasn’t done it yet. I’m not entirely sure how but I’m convinced something got jammed in there
lol thanks for letting us know there's a cable that'll be broken if you're not careful for taking it apart. Would've really liked to know that beforehand and now it's broken.
I don't know how you possibly took it apart without brute forcing it because it's impossible.
THANKS FOR THE BROKEN MOUSE

One last question, if I remove the black plastics on the bottom of the mouse AND I CAN NO LONGER PUT THEM BACK, doesn't it affect the operation of the mouse?@@Purkkaviritys

Went to Best Buy and bought a new one and returned the old one in the box the next day I ain’t got time for this 😂
The weakest feature of this mouse and many Logitech mice are the pads below, that simple pad that feels like black duct take can get loose with time, and without them, it feels rough on the mouse pad.
I dont know why didn't they just make them out of plastic.
They ARE made out of plastic, but a wear-resistant one (Teflon / PTFE). If these would be made out of housing plastic, the mouse would be broken, as soon as the surface wears out.
Hello I want to ask one thing my 502 wont work if I launch a game and switch to desktop the right and left click wont do anything . It sometimes starts scrolling up and down it self by this I mean to say is that It wont work one switching from one to another application
Unless I unplug it and plug it again
@@AsherAmir2002 starting scrolling up and down sounds like the scroll sensor is dirty and thinks you are scrolling even when you aren't and it gets reset when the mouse loses power.

that is an intresting comment to leave to a video about literally a user disassembling a product and then re-asessembling it, and if you mean the teflon pads, those are consumables to begin with.
Slow video, next.
how stupid all these unpacks, reviews and showdowns look with black gloves, as if they are demonstrating Rolexes, but in fact the video shows a bad mouse with a cost of 300 rubles and a brutal overprice
