Introduction
Si votre Logitech G27 ne répond pas correctement, même après l'étalonnage, vous devrez peut-être remplacer son encodeur optique. L'encodeur optique est un petit appareil électronique qui transforme la rotation de la roue en un signal électronique que l'ordinateur peut comprendre. Il n'est pas trop difficile à remplacer, il vous faut juste beaucoup de patience car vous allez retirer beaucoup de vis! Assurez-vous que votre roue est complètement débranchée avant de commencer ce remplacement.
Ce dont vous avez besoin
-
-
Retirez les six vis hexagonales grises de 25 mm avec une clé Allen de 4 mm.
-
Soulevez soigneusement la roue, mais ne la déconnectez pas du reste de l'appareil.
-
-
-
Pincez et débranchez soigneusement le grand connecteur à 7 broches sous la carte PCB.
These screws refused to go all the way back in for me, and one of them stripped completely. If this happens to you, you can get replacement screws that are shorter here - https://www.amazon.com/gp/product/B01MFA...
This works for the G27, not sure about the G25 or any other wheels.
Obviously the screws being shorter means the wheel isn't as strongly attached to the base in this direction, so if you have to do this remember not to put unnecessary stress on these screws by pulling the wheel straight off the base.
bro i need new long cable i think and that connector or just replace the whole thing .. i put new grease, screw it more tight by the encoder so it woulnt go to the left .. wheel works verry nice tho all my buttons and shifter pedals wont work now tho the lights works dont know what to do now.. and now i kinda regreat opening it.. my wheel run so good now just these buttons are off not working at all and it kinda screws up midle of the game..
@alexdinpoik I’ve had the same problem when the 7 pin connectors blue and green cables broke off. First, only the blue one was broken which only took the led indicators gradual increase but all buttons were working then when i tried to plug in back, the green one broke off leading to none of the buttons working but the led indicators just working. Now i’ll try to fix it with iron soldering.
okan can u pls share a video of you doing it? so i can do the “copy paste” hahah where can i buy cables and stuff i need for that? whats the name of these white connectors ? im new to this but share me a link to buy. i rather just try to fix it then buy a new wheel since its a great wheel compare to g29 that has bad software and the other wheels are to expensive. g27 cant be found in stores anymore neither and if im gonna buy one it has to be new haha hopefully u can share some knowlage thanks!
Where i can Buy the 7 pin cable for Main board please
Hey guys!
i broke the 7 pin cable anyone know where can is buy it? Thanks

Vous pouvez maintenant retirer complètement la roue du moyeu. Mettez-le de côté jusqu'à ce que vous remontiez la roue.
-
Retirez les trois vis argentées les plus internes de 37,5 mm avec un tournevis cruciforme n ° 2.
-
Retirez le moyeu de roue et poussez le connecteur au centre du moyeu.
-
-
-
-
Retournez le boîtier et retirez la moitié supérieure du boîtier, révélant la majorité des composants de la roue.
-
Le couvercle du boîtier peut être mis de côté jusqu'à ce que vous remontiez la roue.
Loosen the desk clamps before removing the housing, otherwise you risk breaking something. The housing should come off without having to use any force whatsoever.
-
-
-
Retirez les quatre vis argentées de 7,3 mm fixant la carte PCB verte au boîtier du moteur avec un tournevis cruciforme # 2.
I’d do steps 9 and 10 in reverse order, the connectors are much easier to unplug while the board is secured in place.
-
-
-
Débranchez les trois connecteurs en plastique sur le côté gauche de la carte PCB.
-
Débranchez les deux connecteurs en plastique sur le dessus de la carte PCB.
-
Débranchez les trois connecteurs en plastique sur le côté droit de la carte PCB.
Some of the connectors have locks on them, I would recommend this as a two person job.
I didn't take them off :)
I messed up and broke the cables of the 5 Pin Connector on the right. Can anyone tell me what it’s called so I can buy replacement? The Rest of the cable is stuck in there so I can’t re-use it sadly.
-
-
-
Après avoir suivi le guide des prérequis, inversez votre appareil.
-
Retirez les quatre vis les plus centrales du bas de l'appareil avec un tournevis cruciforme n ° 1.
-
Retournez votre appareil à sa position d'origine et retirez complètement le boîtier du moteur du reste de l'appareil.
-
-
-
Retirez les huit vis fixant le boîtier métallique du moteur au plastique avec un tournevis cruciforme n ° 1.
-
Retirez complètement le boîtier du moteur du plastique.
I found the repair easier to do with the motor still attached to the housing, step 15-16 unnecessary.
-
-
-
Retournez l'appareil et retirez les trois vis fixant le moteur le plus à gauche au support métallique à l'aide d'un tournevis cruciforme n ° 1.
-
Retirez complètement le moteur du support métallique. Cela facilitera les déplacements lors du remplacement de l'encodeur optique.

Retirez les deux vis argentées de la face inférieure de l'encodeur optique avec un tournevis cruciforme # 0, et le circuit sera libre du moteur et prêt à remplacer!
my wheel wont calibrate and sometimes it spits out a “power surge on usb” error and my optical encoder is good, what do i do?
I like this replacement. https://es.aliexpress.com/item/329959435...
At first I didn't calibrate myself. I realised that it has to be fully inserted and satin with the end of the motorbike cylinder, as you can see in the seller's pictures. Then it did calibrate.

-
Lors de la réinstallation, assurez-vous, lorsque vous effectuez cette étape, d'aligner la butée de l'engrenage de roue avec la chenille, comme indiqué sur les deuxième et troisième images.
-
Assurez-vous également que le clip demi-cercle en métal est correctement placé à l'intérieur de la fente.
-
Après avoir placé le clip métallique dans la fente, placez le pignon en plastique sur le dessus du clip et sur le rail.
Thank you ! ! ! !
Step 19: If you disassembled the wheel with the wheel in center position, you have to re-assemble it with the gear in center position, not as shown on the picture. At least this is what worked perfectly for me on the G27! While disassembling, I paid attention that everything keeps in center position.
There is a Timing mark on the face of the linear gear and the round gear, line the timings dots together

Hello and thanks for the guide. I understand this might be off topic, but would you happen to know the pinout of the7-pin connector in step 5? There is no label on the pins. Thanks in advance for your time.
Are you sure about Step 19 alignment. Some other guy with G25 says it has to be dead centre alligned otherwise you get blinking lights.And that's exactly what happens to me.
hi! i reassembled mine positioning it all the way to the right, and i have blinking power light and my wheel do not calibrate. what do you mean by dead centre aligned? i have to assemble it back together in center position, is that it?
Hey, really big thanks for this guide! I opened my wheel and found the optical encoder broken as foreseen. Just bought the brass version, but for the first instance I fixed the encoder by wrapping some thin tape around the edges and cut off the rest. worked well, but is not meant for a long time use.
As I managed to make this fault, please add a hint that when rearranging the wheel (reverse step 1+2 the thin wheel button wires love to slip close to the bottom left and right screwholes with the risk to be squezzed between wheel and wheel hub. Now I have repaired the wheel function and wrecked the upper left button function :-)
You can buy a printed version here: https://www.shapeways.com/product/4FDSWS...
It worked great for me, it shipped within a week and I'm using it now for over 2 years without any problems.
2 versions are sold: 30 and 60 slot encoder.
60 slot is for G25 and early G27 later G27 wheels use the 30 slot version.
The three hub screws in step 6 refused to go all the way back in, and one of them stripped completely. If this happens to you, you can get shorter screws here to replace those very long screws - https://www.amazon.com/gp/product/B01MFA...
Obviously the screws being shorter means the wheel isn't as strongly attached to the base in this direction, so if you have to do this remember not to put unnecessary stress on these screws by pulling the wheel straight off the base.
Also the best replacement in terms of longevity for the encoder disk is the brass ones that you can order here, but shipping takes quite a while - http://cmlaserservice.com/index.html
I tried to 3D print one myself but it didn't work.
can you please share me the motor specifications?
Is this questin for me?
yeah ! I need this motor specifications :)
Repaired with this guide, thanks.
For the repair of the optical encoder I used a washer.
not encoder?? Washer??
is it work sameway??
I user a washer to repair the broken optical encoder.

Excellent guide and thanks for the publication and your help !!!
!!!!Took me a white 2FIX it but!!! LISTEN! !!If Your wheel aiant straight in center with good or new encoder TRY first in windows controllers menu .Wherę IT shows controler. Devices while pointing at your g25,7dfgt Device :Press Ctr+shift and right Mouse to engage wheel calibration. Thank you and You Welcome ;)
Hi everyone. You can buy a replacement from there. Optical encoders available with 30 or 60 Slot. For 30 Slot check out this https://www.ebay.com/itm/264059488231 and for 60 Slot check out this https://www.ebay.com/itm/264059495927
Where can I order the optical IR sensor? I’m not getting my drive on without one …
If someone tries do do this: Do not do step 9 to 16. It’s completely unnecessary and will just make it harder to assemble again. You can remove the cable and casing as described in step 17 just fine with some fiddling.
If you disassemble it completely as shown in this guide you will have to align the stop gear to the track again (step 19), which just doesn’t work well by visual estimate alone.
Hello
I changed my optical wheel, but after that my g27 doesn’t calibrate : power led is blinking, but the wheel doesn’t make its calibration process as the wheel is not moving… After three attempts, power led is blinking fast and that’s all.
I made a video of this problem : https://youtu.be/hihREK_QC1Q
I thought my optical wheel was too low (or too high) on the engin axis, so I tried to change its position but no effect.
If you have any idea…
I had the same issue. If you have a 3d-printed optical wheel replacement make sure to completely cover it with black marker. It has to be all the way black otherwise light can shine through the spokes and the encoder sends an error which results in the issue you’re having.
So even if it looks black.. just try again with the black marker..

how many slot encoder do i need?
Good day sir
I have lost the 5 pin adapter
Please help me i am unable to find 5-pin adapter for encoder part online
I want to purchase it
Hey,
I switched the encoder on my g27 with a brass one yet I'm facing another issue. With the old broken encoder, it only calibrated to the right. With the new one, It calibrates all the way from right to left but it doesn't come back to the center. Then it repeats the process 3 times but nothing happens. What could be the issue?
I've read people saying that I need to readjust the black plastic to the center on step 19.. any ideas?
