My Logitech G25 was broken for quite some time and I wasn't sure what to do. After a few long hours of searching online I figured out what the problem might have been and after I opened up the Logitech G25 I found the problem. There is a little black disc, which is called an optical encoder disc, that usually cracks after regular wear and tear. This part either needs to be fixed or replaced. I tried to fix mine by glueing the crack but I was unsuccessful. I decided to purchase a brass replacement and the logitech works like new!
Here are some photos of the broken original plastic encoder disc:

Logitech G25 Steering Wheel Issue
Just to add a note here that I ordered the brass encoder disk from Thailand last week and have already received it - so I can confirm they are still available in 2021. Many thanks for this video - you saved my G25!
My G25 has been sitting in a box for over 5 years. With iRacing getting popular, I pulled it out and found this to my dismay. Thank you for the tutorial. I'm going to see if I can use my soldering iron to melt the cracks back together for a temporary fix, I ordered a 60 slot from CM Laser. Thank you for that link as well!
Hey, no problem! Glad my video helped you out. Have fun playing with your new and improved G25. Cheers!
Thank you man, your two videos really helped me. I managed to fix it without buying the brass encoder. So here is my story if it can help someone:
The first time i tried to glue the crack, but when I put back the encoder on the motor it cracks again. So the second time I bought a washer. M5 inner diameter. I put the washer, It didn't crack anymore. I assembled everything back and plugged in the wheel. It calibrated but it was slightly off (like 10 degrees). The problem was that the washer was too thick, the encoder wheel was far from the black sensor (make sure your encoder wheel is close to the black sensor but doesn't touch the circuit board) so I dissasembled again and removed the washer. I cut a piece of metal form a cola can. I made it the same dimensions as the washer. I put the new washer on the encoder wheel and I couldn't believe it but this has worked.
Awesome stuff! Did you make a video tutorial on what exactly you did with the cola can? Or will you make one soon?
good video man i used it when doing my first encoder, but just a heads up for anyone looking at doing this. you can just pop the plastic cover on the motor off and change the optical encoder as the g27 is seen at the very start of this video. no need to remove circuit boards, plugs (apart from the one in the back of the motor) or the main steering unit with the motors attached. its more fiddly and you have to be more careful but it can be done. i just done it tonight on my 2nd wheel
How did the plastic encoder wheel crack? In my case the encoder wheel was moving freely on the axle and I managed to glue it and fixed my problem but it wasn't cracked luckily. Thank you for doing this video, you're helping many people out there!
My wheel was shifting more and more to the side. As it turned out, my disc was indeed cracked exactly like in the video. I then glued it together. It works for now and I hope it will do until the brass disc arrives in 2 weeks.
Anyway, thank you very much, you helped me a lot!
Since you purchased the wheel from eBay and it never worked to begin with, I can't say for sure that nothing else may be broken. However, since you mentioned that you have the same crack on your optical encoder disc then my best guess is to replace the disc and see what happens. I know its a risk spending 37 USD on the brass replacement and it might not even solve the issue but thats what I did when my G25 was broken and it fixed the problem.
Hope this helps!
my g25 started acting up today. Followed your excellent tutorial and, jupp, three cracks in the disk. Already ordered the brass replacement. Now the waiting game begins XD.
You are my personal hero!!! Just bought an old broke G25 and repaired it like you explained. Thanks so much! :)
Whomever gave this a thumbs down should change their mind. Everything written here was spot on! Thanks for the help
I expect that it's a polyamide (Nylon) disc. If that's the case, it cannot be glued, the low chemical surface energy causes it to reject adhesives.
When the material comes out of the mould, it's somewhat brittle, and is conditioned for several hours or about a day in humid environment to absorb around 4% of moisture (by weight and by volume approximately the same). It becomes tough and flexible and expands in size a little. Then after it's installed on the shaft, it will lose a little moisture and will hug it tight. It will continue losing moisture, because it sits on a pretty warm shaft on a pretty warm motor, and it will continue shrinking and becoming more brittle. Eventually, the shrinkage forces will cause it to split, as it continues shrinking around the shaft, the forces are immense.
I tend to repair some mechanisms which share the issue. I repair small polyamide gears by copying them, creating a single-sided mould with silicone putty, and then casting epoxy into it. I usually use Uhu 300 epoxy, and i mix about 10-20% more hardener than binder, to make it more flexible, since in 1:1 epoxies the hardener usually contains plastifier, in this one for sure. Then i hot cure it, i throw it on the bed of my 3D printer at 80°C or before i used to have one, i'd just used a hair drier.
I don't know whether i'd be able to copy the encoder this way, whether the silicone that i use can actually be encouraged to go into all these little holes and then stay together while the master is removed, or maybe liquid casting silicone needs to be used instead. Nowadays, one could also 3D print a replacement. You can find ready made 3D models on Thingiverse. You can then order the prints in polyamide from Shapeways, or in polyamide or resin from PCBWay or any number of companies - this is all very inexpensive. It also seems barely just about printable on a commodity FDM printer in PLA, won't look great but might just work, or might need a tighter nozzle than standard (0.4mm is standard, but down to 0.2mm are available) but it is doable.
There appear to be a bunch of guys in China offering 60-slot encoders specifically as "steering wheel encoder for Logitech", not cheap though. These are made from stainless steel. So you aren't limited to a single supplier.
9 years later and I'm watching your video with a broken g25 haha
Thanks a lot for the video. I ordered one from CMLaser and my G25 is back!!
YAYYYYYYYYY
I just want to confirm that I got my encoder from the same guy within a week (Shipped from Thailand to The Netherlands). I placed my order on June 26, and got it today (July 3, 2013). I should also mention that I used mike's G25 disassemble videos to open up my G27, so hereby Narain's question is also answered with a "Yes". Now ... let's re-assemble the thing! I'll reply the results when I got to test the new encoder .. -fingers crossed-
Thank mate...I tightened my screws but still had issues, checked my encoder and yes it had two (2) cracks. One was all the way through and the other was half way through. Ordered new one and should fix the problem...Thanks again.
I'm glad the video helped you out! Cheers!
1: Close the crack with som fast glue and some pressure. 2: Glue a steel washer on the disc, for enforcement. 3: Clean for glue residue near the small encoder holes.
The optical encoder for my G27 recently broke and its out of warranty, so I am having to replace it which is why you video is so helpful. But I was wondering does the inside of the g27 look like the inside of the g25 or is it radically different? just want to know before I take it apart
I honestly don't know if its the same or not. I'm going to assume that it is maybe with an extra wire or two but I really don't know. I recently sold my G25 but hopefully I'll be picking up a G27 when I get some extra funds. I'll open it up and compare.
Thanks for the video! After you put on the encoder wheel on the shaft, do you apply glue?
You should REALLY include something about the wheel stop (toothed plastic piece) that falls out when you pull the servo motors. I'm the second person I know who this has happened to and I had no idea where to put it. With a little help I eventually figured it out but my buddy gave up and had yo buy a new one. You assumed we were too smart :) GREAT VIDEO THOUGH, saved me 300 bucks and I didn't even need any glue. Mine turned out to just have all four of the mounting screws loose! Thanks!
Is that the part that connects with the steering column? If so, I think I lightly covered that in Part 2 of this video. I wish I still had my G25 :( I'd open it up and make another video going into further detail on that toothed plastic piece as I get quite a few questions regarding that piece of the G25. Thanks for watching though, it means a lot :) Cheers!
how is this holding up so far, any updates?
my g25 has been sitting in a box since i had the flashing power led and dead steering wheel. and debating if 37 is going to fix it.
thanks for making this video
did it work?
I watched your video and left a comment. My best guess would be that you have a cracked optical encoder disc but before you start replacing anything, check to see if you have the same issue with another system such as a PS3. That's if you have access to one.
Awesome! Just ordered mine. Mine broke as I was downloading asseto Corsa
actually me too wtf
Great video!! Does this also work for Logitech G920
The light blinks aswell when you have another hardware that interfeares with the nadwith the G25 is running on. In my case my web camera and my headset when on at the same time, makes the g25 act up. So before you complete disasample your G25/G27 Try to remove webcamera´s or headsets and see if its still doing it :)
8 years and this is still helping, spent 40 minutes unscrewing everything and now I have to buy a 30 dollar replacament so it doesn't brake, I don't wanna do dis no more. I just wanted to uscrew it, re plug some shit and put it back toghether, not wait a ferw months for a stupis small wheel to get delivered all the way to Poland
hey! just wanted to let u know what u¡ve made my christmas, this morning my g25 got "broken" ... now its working again, thanks a lot!
Cheers!
Thanks a lot Man, i glued mine together. Its back up and running again.
YAYYYYYYYYY
Hi Mike..your video are awesome, i have a dfgt and same problem, i open my wheel and noticed the round thing is slightly broken..so i'm interest to know where can i order the round thing ( brass type )?
Can you help me.. please..thanks!
Can you told the site where you bought this piece? What is exactly the name of this piece? How can I search?
My G25 sometimes do this failure, it is my second G25 so the older also do the same.
thank you so much, your video was very helpful. i'll try to glue the encoder first with a special glue for scale modeling and if that doesn't work i'll go with the brass one. i'll let you know whats working
YAYYYYYYYYYYY
thanks man , i have the same problem with my G27 , and orderd the part trough the link you put in your discription thanks mate !!!!!
Thank you for this video! Is there only one encoder or is there one on each side? I see 2 similar motors on your unit there. Im wondering if I need to order 2 encoders or just one. Thanks again!
Just one.
Thanks for the video, very helpful. I have a couple questions though. When you remove the old encoder disc and put the new one on, is the shaft/disc keyed and if not how can you be sure the holes are in the right position for the purpose of calibration? Also, if not keyed to the shaft, what's to keep the disc from spinning on the shaft?
Sorry by the way if this question has already been asked, there are a crap load of comments on this video ...
its the same in the g27? i cant find a guide. i fix encoder 2 years ago and i dont remeber i do it
Thankyou for making these vids they helped me out big time!!! Brother you are a legend!!!
YAYYYYYYYYY
Thanks for the video, my wheel just broke and the warranty just expired. I hope to save some money by fixing it myself.
YAYYYYYYYY
Thanks man, just ordered my encoder.
Also, on your blog the link to your youtube videos is broken in this sentence:
"Definitely check them out and be sure to watch my UA-cam videos!"
Just to let you know ;)
Thanks for the heads up! I greatly appreciate it!
hi thanks for this. my encoder actually looks ok (no cracks at all). The problem i was having was the steering (left and right) wasn't regisering in the game. the only thing working on the steering wheel was the rev light stay on constantly and the paddle shift would work. i too had the blinking light on my shifter which is why i have opened it up and found the encoder disc in good condition. any idea what else could be causing this issue on the steering?
Thanks for the video! My G27 has recently got an issue when it is plugged in, and does the calibration thing, it makes a fully right turn, a fully left turn, then stays there without coming back the dead center. Is this a rotary encoder issue? Should I be worried?
I got a G25 that did the same thing. Ok, mine also stopped working (it wasn't stiff or something like that). Might be the power cord or might be it.
@@maple7093 I later found out it was Windows Update that messed up my G27 driver. I had to uninstall its driver (that Windows 10 automatically put on) every time there was an update, and then reinstall the good old Logitech profiler thing to get my G27 to work.
it culd be the encoder but at same the software from logitech its a 50 50 just try first re install the software
Thanks for the tutorial mike, followed your instructions now G25 is all better Awesome , sadly my son cannot use it with his PS4, damn you sony :(
Excellent video. I definitely have a cracked wheel. Sigh. Exactly as predicted. I'm about to order a new one.
Question though as I seem to be missing a tiny piece of info... There's a rectangular piece of plastic with gear teeth and grease in there.... How do I know exactly how to get it back in properly? It seems like it would have to be aligned in some way otherwise the wheel would have limited travel in one direction or the other.
Thoughts?
And thanks for the great work. You've done us all a great service here.
+Bill Griffith Thanks.
I lined it up as center as possible. It was trial and error for me. Luckily I got it right the third try. I do not know of another way of aligning it perfectly.
+mikeschmeeedotcom I stared at it for a while and I ended up getting it REALLY close to perfect. Just an FYI...I didn't get the brass part. I took my cracked wheel and found a small nylon washer that was a little too small to fit over the shaft. Then, carefully trimmed the washer with my Dremel too for a nice firm fit. It constricted the cracked wheel back to perfection. A tiny bit of cyanoacrylate to keep it safely in place (it's tight and I'm sure it won't move anyway) and it's been working like a champ. 19 cents to fix.
+mikeschmeeedotcom tool. Damn autocorrect.
+Bill Griffith Cheers!
Very helpful video, thanks a lot, I have the same problem and I will order the same one like you did...very helpful
Bought encoded wheel. Slide it in. Wheel doesn't do anything now. All buttons working, but no steering at all.
To give you more details, I get a flashing power light, and my RPM lights are at half...
Make sure the new optical encoder disc is not touching any of the sensors. It has to be in just the right spot for the wheel to work correctly. Be sure to watch the second part of this video. It's on my UA-cam Channel
Great video.Thanks a lot for your help. I also had my encoder plastic disc cracked. I glued it with loctite and the problem persists (software does't recognize the wheel - green light blinking on the shifter - , only recognizes pedals, shifter and all the buttons, including the ones on the steering wheel). Then I noticed that the encoder disc was a bit loose on the 3mm motor shaft. I,ve glued it too. The problem persists.
I can order one of these brass discs that you refer, but honestly, What difference it will make as my plastic disc is now well glued and tight to the shaft? I wonder if it is not another problem. In your oppinion, what difference can make the brass disc to the original one well repaired and tightened? Do you know any other hardware or software problem that causes this?
Hello, thanks for the comment and compliments.
I don't know of any other hardware of software issues.
The brass disc is simply stronger and will not (or atleast should not) crack as you have seen from the plastic disc. That's the only difference I can think of.
If I had to take a guess I think the plastic disc is just simply not strong enough and overtime its prone to cracking?
I hope that helps.
Cheers!
I'm currently on the same situation I have the same symptoms you guys mention that of the blinking green light on the shifter. I am not sure if the problem will be fixed if I buy this expensive brass encoder however and it's quite a bit of money to try... Is your issue fixed after you replaced the encoder with the brass?
I didn't replaced the plastic disc with the brass disc. I found a second hand G25 Wheel and I bought that wheel. But I suppose that If I had replaced the plastic disc by one of those brass discs the problem might have been resolved.
Mike, tanks so much for sharing this info with us. I suspected mine might have small crack as well (G27) opened it up and it confirmed it. My calibrated slightly of centre as well. What I wanted to ask was if ur force feedback got any weaker because of this? my ffb is much less vs my buddys g27 on the same game with the same settings. Basically what im asking is did this only solve your calibration or did it improve other aspects of the wheel as well. Btw the G27 is exactly the same inside down to ever connector.
Honestly, I cannot remember. I sold the G25 a long time ago as I was in need of some money and I haven't gotten back into the scene just yet. I don't think the force feedback got weaker but like I said, I honestly can't remember. Sorry about that. When I installed the new optical encoder disc, I noticed that the disc has to be in a specific sweet spot in order for everything to function perfectly. I think it has something to do with the slightly larger thickness of the brass disc. Perhaps its weight as well. So maybe it has something to do with the positioning that you currently have it in? I'm not sure. Sorry I couldn't have been of more assistance.
Thanks Mike. I just made the order from CMlaser. I will post the feedback here as soon as I receive the new disk and install it. Thanks so much for your detailed videos. :)
THANK YOU I was wondering what was wrong with my wheel and found out my encoder is cracked thanks
I've just fitted a new encoder to my G27. At the third attempt I've now got it to configure correctly on start up. However, now I have a really weird problem.If I have FFB set to on, pressing any key on the wheel or pedals sends the wheel in to a crazy spin. If I set the FFB off, then all the buttons and the wheel work perfectly. I've obviously done something really stupid with the rebuild but I can't see what. Any ideas??
glsammy My problem is now solved. It turned out to be a faulty front USB port on my computer. Connected to a different port on the rear and all works perfectly.
Hi, Thank you so much for the video. I´m from Brazil and was a little bit afraid that just lost my G27. My question is: There is only this site to buy the optical encoder? Is 30 dolars for just one? Brazil kills me with "real".
Just opened my G27. i dont think my optical encoder is broken, but its STUCK. I didnt make it, because its very strong. I dont know what to do.
Guilherme Calciolari Maybe you can remove the disc and slide it back on again? Maybe just play around with it so it won't be stuck? I'm not too sure.
I only know of the one website. I'm not sure if there is another one somewhere closer to your location.
I'm not sure how the encoder disc cracked. I was playing GT5 one day and the vehicle started to lose control and spinning out. Then the LED on the shift stick assembly started to blink. After doing some research, I realized it could be a bad encoder disc, which in my case, it was.
How long did your encoder wheel take to arrive? Just bought mine.
I think it took about 3 weeks to arrive in Canada. Check my website blog as I wrote a little review on the entire thing.
the link is broken do you have some brass encoder disk replacement.? Also maybe it is the infrared sensor too do you know where i can buy a replacent also the main board?
Maybe try second hand websites for new and/or used G25 or G27.
Thanks for the informative video +mikeschmeedotcom - it turns out my encoder is cracked (plus when I saw the flashing light on the shifter I knew it was the same issue as mine). So I'll be ordering a new encoder disc from Thailand to Brisbane. Cheers buddy!
Update 07/07/16 - Ordered the encoder disc from Thailand, great quality and thanks to CMLaser and mikeschmeeedotcom it is working again. I would add, to make sure you align the geared board fully to the left to ensure it can calibrate properly - and I also had to gently push the encoder disc closer to the black optical reader as it couldn't read it the first time.
Other than that it works beautifully and I don't need to buy a new wheel now. Thanks so much guys!
Glad it worked out!
mehdi maybe google search the name/model of your wheel for some fix results - most wheels of this age will use an encoder to translate your turning of the wheel to a unit of measurement that your PC can understand. Hope that helps
my G27 doesn't steer anymore, all other buttons work, pedals and shifter, the only issue is the steering.
The shifter light blinks and if I plug the wheel to a different USB, it doesn't detect as G27, it detects as Logitech Driving Force model.
I checked the encoder and it's cracked indeed (but still in one piece).
I'm not so sure that issue is causing this problem, can it be that a slight crack can do all this? anyway I tried to glue it, but the issue was not solved.
Did you have those exact symptoms?
Is this what causes the wheel to be turned to the side in order for the car to go straight? I had this since day 1.
Yeah im pretty sure it is. I also got this sadly, bought a used G25 but i only saw this happen when i actually drove with it at home :/
Hi Mike, After your video and searching some other foums I bought the optical encoder from cmlaser, I installed it and checked 10 times before trying G25. I started a lap at to test G25 but after a couple of minutes alligment was gone. Tried maybe 20 times so far but alliegment just goes off during the driving. Do you have any advice?. Thank You
Hello, I'm sorry to hear about your experience. It sounds very annoying, atleast I would be annoyed if I were in your position. The only thing that I can think of is the disc is not set in the right position. I mention in part 2 of this video that the disc has to be aligned a certain way in between the sensors. That would be my best guess without seeing the Logitech unit in person. Other than that, it may be something else that's causing the issue.
Glue it to the shaft it's probably shifting while you are moving the wheel resulting in it no being aligned
Hey Mike thank you for your video!
I have applied the new encoder correctly but now I have a weird problem, the wheel after around 10 minutes shuts off of windows, the green light on the shifter is perfectly lit and it also keeps the last position the pedals were in (if it shuts off in the middle of a straight then it keeps on the gas fully) if I replug it, it works for 10 mins again. Any idea what have I done wrong because this didn't happen before I've took it apart.
+GyenesLaci1 *Update*
I have unplugged the g27's shifter and it works great no problem with pedals and steering wheel but a new problem was born somehow in someway the brass encoder spins or does something on the metal thing you put it on and it starts steering off center and then the steering dies. It slides off of it's position after a few laps progressively and bam it looses the connection of the wheel.
Mike! Thank you!!
My G25 started drifting off center and thanks to your guide I was quickly able to establish that my disk was indeed cracked.
Ripping apart a few old ball mice I found a VERY similar disc, that when drilled trough made the wheel usable again.
Still I am a bit of center with the new disk, It calibrates 100 % but immediately drift off to one side a few degrees when in use...... :(
Question: Can This be cause by misalignment of the center "cog" plastic piece or do you think my disk is not precise enough?
I am a bit hesitant to splurge for a Thai metal disk, unless I am sure this will work 100 % as funds are limited...
Thank you in advance for your thoughts on this!
Rune Løkke It could be either or. Start with the centre column or "cog" as you call it and try to get it as perfect as possible. If it's still off a bit then it could be the disc from the old mouse.
From what I remember, the disc that can be found in an old computer mouse has to have the right amount of holes or slots that perfectly match up with the G25 optical encoder disc. If you look at your optical encoder disc in the G25, you will see tiny holes or slots near the edge. The G25 computer reads those slots in order to calibrate the wheel correctly each time it starts up. So make sure the disc you found in your mouse has identical.
I guess the last resort would be to purchase the brass optical encoder disc from cmlaserservice in Thailand.
mikeschmeeedotcom Thank you for the quick reply; I am going to try to realign the center column first I guess, even though my solution was a bit "ghetto" it did seem to work, as the wheel perfectly centers on boot..
..its damn hard to count the holes, but it certainly looks identical when held on top of the (partially broken) old one.
I guess if this does solve it, ill splurge for the Thai solution.
Have a great day Mike, and thank you again!
Rune Løkke Not problem. Happy to help out. Let me know how if it works out.
Cheers,
Mike
I'm not sure. Make sure all of the connections are secure and make sure you have the necessary drivers for your computer.
Is the G25 comparable to the G27 for the noise? Is it possible to grease the gears to make it silent? Please I need help it will be my first wheel. I want a wheel under 180$ and I got a deal for 150$ on the G25, not sure if I should get it
I'm honestly not too sure if you can grease the gears. I mean, I'm sure you can but I wouldn't. It's not too loud, my room echos a lot. Maybe try it out at a store that has it on display before purchasing? The G25 and G27 are the best wheels that are available, in my opinion.
mikeschmeeedotcom I finally bought the G25. Not disappointed at all! Its not noisy at all! The videos on UA-cam are so misleading for the G25's noise level! thank you for the reply :) Got a question: do you have any way to make the shifting noise less clicky ? I find the "plastic wrapping the ball" trick not so long-lasting after the wear on the holes on the plate inside the G25's shifter
tonytober I'm not sure how to do that. I've only modified the shift stick so it has a heavier feel as it would in an actual vehicle. My solution to this light issue, is to turn up the volume or wear headphones and listen to the sweet sounds of engine and exhaust!... however, GT5 sound effects are not that great.
mikeschmeeedotcom
Why do you think this sensor wheel breaks? It doesn't even touch anything that would bind on it does it?
I'm sorry, I have no idea. If you are experiencing similar issues as I have explained in this video than you can open the unit up and see if it needs a new optical encoder disc.
thank you for this informative video
Hello I have a g27 I don't know what the problem is I try to power it up and nothing happens no calibration at all I've tried replacing the fuse in the plug and it's still the same ? Any ideas
Could this be why my steering doesn't work, like...At all? I'm getting 24v from my power supply so I googled it and I can't find any other fixes, except this.
Open the G25 and see if your optical encoder disc is broken. Or maybe something is just loose. Either way you have to open the G25 casing and look inside.
It's identical man, I took apart mine a few weeks ago.
Thanks for the link, but 37$? It is too much for a little replacement.
Anyone know other cheap site?
why do I not want to lose the washer? what does the washer do?
windyman56 leaves a little space between the electronic plate and the screw so the pcb doesnt break around the hole
The steering wheel is turned off when i connect transmission? How to fix that please answer me! :)
I'm just getting into pc steering wheel. Is there any benefits from swapping from a 30 slot encoder to a 60?
I honestly, do not know. Sorry.
Also, apologies for the late response.
@mikeschmeeedotcom it's all good. I was reading into it alittle. Apparently there's some sort of light in the wheel (assuming a laser). It passes through the slots that are responsible for basically sensitivity. The more slots, the more sensitive it is, apparently. Can't confirm or deny as I have done the mod at this point. I appreciate you responding, thank you 👍
My Logitech G25 is now fully functional after replacing the optical encoder disc. My steering wheel showed up when playing but the wheel didn't move. Just nudged a little bit and I had a flashing light on the shift stick. I opened the G25 up and I noticed that the disc was cracked in three spots so I replaced the disc and now it works again! You might have a similar issue and the only way to find out is to open it up and check. View my other videos and photos for full details
Well, I can't make a video because I need to dissasemble my G25 again and I am afraid I will break it :D. But this video pretty much explains what I did:
/watch?v=gnGY0lLnv0A&t=2s.
But I instead of the washer I put a piece of a cola can or beer can. I just cutted a square from the can with scissors. Then i placed the washer on top of it and i glued it so it doesnt move when I cut around the washer. So I cutted the square and now I have circle the same diameter as the washer. While the two pieces are still glued togheter, I grabbed a screwdriver which had the same inner diameter as the washer. I started twisting it (drilling) it until the inner diameter of metal piece had the same as the washer. Now I have two washers - one thicker and one thinner glued to each other. I seperated them and put the thin washer on the encoder wheel. If it doesn't fit you can try again to enlarge the inner diameter, but don't make it too large because It will be loose. When my homemade washer finally fitted to the encoder wheel, I put a very little amount of glue and then putted back the encoder on the electric motor.
I replied on the wrong comment :D, but you will get it
No problem. Glad it helped!
Thank you very much !!!!!, I let you know with my results on GT27 as soon as I get the encoder
and resemble my wheel.
Great video anyway !!!!!
And Yes !!!!
I install the bronze encoder following your guidelines and now it works perfectly
perseus spiliopoulos καλησπέρα.έχω την g25 και δουλεύουν όλα ακόμα και τα κουμπιά πανω στο τιμόνι εκτός απο το τιμόνι...αν ξέρεις κάτι θα μπορούσες να μου δώσεις τα φώτα σου;ευχαριστώ!
Καλημέρα, Πιο είναι το πρόβλημα με το τιμόνι ?
perseus spiliopoulos το πρόβλημα είναι οτι δε δουλεύει το τιμόνι...όλα τα αλλά δουλεύουν κανονικά ακόμα και τα κουμπιά πανω στο τιμόνι και τα paddles...επίσης απο τα δυο πράσινα λαμπάκια που είναι στον λεβιέ ταχυτήτων το αριστερά μου ανάβει κανονικά και το δεξια ανάβει λίγο ίσα που φαίνεται...δε ξέρω αν σου έδωσα μια ιδέα με αυτά που σου είπα...
έλεγξες αυτό το ανταλλακτικό που δείχνει στο video ?
Αν είναι ραγισμένο μπορεί να μην κινείται καθόλου το τιμόνι ή να κολλάει δεξιά ή αριστερά και τα λαμπάκια (G27) πάνω στο τιμόνι είναι συνεχώς αναμμένα.
i just saw your amazing videooo !!!!!! i opened my g25=shit) and it was totally broken,,, thank u man !!!!!!!!
My G27 doesn't steer anymore, all other buttons work, pedals and shifter, the only issue is the steering.
The shifter light blinks and if I plug the wheel to a different USB, it doesn't detect as G27, it detects as Logitech Driving Force model.
I checked the encoder and it's cracked indeed (but still in one piece).
I'm not so sure that issue is causing this problem, can it be that a slight crack can do all this? anyway I tried to glue it, but the issue was not solved.
Did you have those exact symptoms?
I don't know why it's showing up as just the DF model, but on my G27, the encoder was cracked, albeit slightly, yet that caused the calibration to go haywire. After replacing it, fixed it. I think to fix the DF problem, is to reinstall the drivers for it.
Does this work for g27 too?
yes its the same steering wheel just ohter metal frame ohter shifter and ohter buttons and weker motors but from inside its the same
Hi can enyone plzzzz help!
My g25 is sending a curent to my wheel if i touch the metal part it gives me a small shock!!! I took it apart but could see no wires touching or enything i put it back together and still same plz help thanks
My g25 seemed to need frequent recalibration so I ordered a brass wheel from a US source, turned out it was a missing screw in one of the motors but I put the new wheel in anyway. Now the PC doesn't recognize wheel movement. ☹️. Tried brass and plastic, wheel does it's start-up dance so it's getting power. Connections look solid. Any clue?
It's been a while since I played around with the G25, but I remember having a bit some small calibration issues if the rectangular bar that connects to column of the G25 unit does not align perfectly. Maybe it's that? It basically has to be dead center, otherwise the calibration will not work on start up, and the gaming system might not recognize the wheel. That's all I can think of at the moment.
@@mikeschmeeedotcom Thks. It w maybe out by 1-2 teeth, seems centred now. Flashing power light as well, normally that means bad power unit but main board is getting 24v, motors are getting 16v and encoder is sending 4.8v so I’m scratching my head.
@@artmcewen3165 Interesting. Could it possibly be some bad and/or loose wiring somewhere?
@@mikeschmeeedotcom Not that I could see. I suspect something is fubar in the board itself.
where to find this spare part?
I have repaired my encoder with a washer that fits snuggly, and I have reassembled. However when I power on the wheel does a small turn then stops, then a few seconds later is tries again then stops again. The lights are all lit up and when I go to the calibration the buttons are all working and the pedals but the left right axis has no movement at all. Can anyone advise what could be causing this and what connections I should be looking at for issues?
I have the g27 and have the same problem. Also a crack in the plastic optical encoder disc. So i go and order an rvs encoder disc. but before u order an replacement disc, take a look at the one inside of your wheel. Cause i have an old version of the g27 and this one have 60 slots in the disc. But i have seen also disc's with 30 slots, so be aware of wat you actual need. Otherwise you did u bunce of work and think it is fixed, and try to play a game and see it is stil not working.
you are a legend
Hi, My son bought one off ebay, seller said untested, all works except the steering. The wheel moves when plugging in USB, but doesn't calibrate at all. Just took apart and wheel is cracked but still moves. Its not a case of losing calibration, it never calibrates in the first place - dont want to order a wheel if its something else?
Matthew Kirby If it were me, I'd still order a replacement optical encoder disc.
The disk was fine, it was a loose connection where the power goes to the board. works fine now!
Matthew Kirby that's great news! It's always nice when things are easy. Cheers!
are the washers important I kind of lost mine
They prevent the screws from coming loose by vibrations. If you lost them it's not a big deal. Just put a piece of rubber under the screw instead (you can cut it from rubber band or use rubbers from a bicycle repair kit, which is what I did to prevent the sensor from coming loose again).
where i find that think with infrared sensor .
So... I've bought and installed the brass replacement and it still seems to drift off after a few corners of drifting. Any help?
Make sure the 2 screws that mount the plastic piece (mounted to the back of the motor) that the small circuit board mounts to are tight and make sure the screws are tight on the small circuit board itself. There is a sensor on the back of the small circuit board that reads through the holes as the encoder disc spins and if the screws to the plastic mount or the circuit board are loose they will wiggle around enough to give the wheel an inaccurate reading during calibration. From what i have seen and read while researching the cause of my wheel problems, it seems that the screws coming loose on that plastic mounting piece is as notorious of a problem with these g25/27 as the factory encoder discs breaking, both of which tend to cause the same problem.
Brad B I've already resolved it but thank you for your time and effort!
i have problem please help ! 2 days ago i played on g25 then suddenly my wheel didnt work , so when i plug it , it do not rotation and when you turn it it doesent turn back and not work. sorry for bad english ! i have bought it used and clutch has not worked and 900¨¨ degrees only 180 and H shifting not worked :D so if you know problem please help D:
thanks for the vid mate, very helpful :)
YAYYYYYYYYYY
what is the problem when the Optical Encoder Disc does not work ?
What can I do if one of the motors is weaker and makes a strange sound? How is it fixed?
Unfortunately, I do not know. Very sorry to hear, and sorry I could not be of any assistance.
I got around to "fixing" the sensor and after putting it all back together I now find there's no power to the unit! I just realised I never unplugged it while working on it......so does this mean I've shorted it somewhere and ruined it? I've tried swapping the fuse in the mains plug but still dead.
That's unfortunate, sorry to hear. Honestly, I'm not too sure what to do. Perhaps using a multimeter to check all of the connections, fuses, etc., could help and to ensure power is running through the entire unit and to all areas of it as well?
@@mikeschmeeedotcom Yeah fair enough, I'm no wizz with electronics so it'll probably end up in the bin . It's not so bad I have a T-GTII now , lol. Just a shame to have gone to all the trouble of taking apart and put back together. I blame youtuber for not telling me to unplug it first - just kidding that's just common sense when taking-apart electronics.
@@Substance2020 hah! Yea, maybe I should have mentioned to unplug it. Don't throw the unit away, maybe I'll grab it off you sometime and try to fix it. It'll be an excuse for me to create an updated video.
The T-GTII looks pretty sweet. Congrats!
@@mikeschmeeedotcom Nah I messed up(again) didn't do my homework - DD is the way to go. I thought Trustmaster was a leader and their latest and greatest wheel was the one to get - same old cogs and notches. I might get around to finding the electrical fault sometime, either that or I'l pull the motors and use them for something.
@@Substance2020 Dang, that's too bad. Live and learn I guess? Well, if you ever get around to tossing out the Logitech, let me know. I might be able to grab it off of you.
wow im surprised how whimpy the motors are . i was expecting something bigger
so fare i manage to get to the two small screws and omfg i cant get them off they are so tight
at the g27 as well too but i buy an g25 from it funcnion not from design the g25 is my best wheel in 2020
i bought a new brass encoder and it wont even calibrate fully? help..
All I can recommend is make sure the disc is in place correctly along with that bar right behind the steering wheel. From what I remember that part has to be centered. Mine did not calibrate correctly until I had that bar centered with the steering wheel. Sorry I cannot be of more help.
Thanks for sharing.
No problem.
I have a brass encoder on my G27 and its working, BUT when i turn the wheel on, it turns all degress to the left side and then, I need to manually turn some degress to the right, so i can play games. The force feedback on the left side is weak and i suspect that my left engine has some problem.
Anyone here has experienced the weakness problem?
thanks!
Got my one. Put it in. And my G25 still won't calibrate. What can I check.
Look if all motors are tightened
Hello, I was wondering something. This steering wheel uses electric motors with brushes, when these will consume as in all brush motors how do you do? 🙄
speakt in spooky: there ... is no way ... do do this... ---- MUHMAMAMAMAMAMAMAMAM but no there is no way u must buy new motor
Does anyone know where I can get an encoder so it won’t cost me a lot of $
