If your Logitech G27 will not respond properly, even after calibrating, you may need to replace its optical encoder. The optical encoder is a small electronic device that turns the wheel's rotation into an electronic signal for the computer to understand. It isn't too hard to replace, you just need plenty of patience because you'll be taking out a lot of screws! Make sure your wheel is completely unplugged before starting this replacement.

Remove the six gray 25mm hex screws with a 4mm allen wrench.
-
Carefully lift up the wheel, but do not disconnect it from the rest of the device.
-
-
-
Carefully pinch and unplug the large 7-pin connector under the PCB board.
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!

Rotate the housing back over and remove the top half of the housing revealing the majority of the components of the wheel.
-
The housing cover can be set aside until you put the wheel back together.
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.

Remove the four 7.3mm silver screws attaching the green PCB board to the motor housing with a Phillips #2 screwdriver.
I’d do steps 9 and 10 in reverse order, the connectors are much easier to unplug while the board is secured in place.

Unplug the three plastic connectors on the left side of the PCB board.
-
Unplug the two plastic connectors on the top of the PCB board.
-
Unplug the three plastic connectors on the right side of the PCB board.
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.

After following the prerequisite guide, invert your device.
-
Remove the four center-most screws from the bottom of the device with a Phillips #1 screwdriver.
-
Invert your device back to its original position, and completely remove the motor housing from the rest of the device.
-
-
-
Remove the eight screws attaching the metal motor housing to the plastic with a Phillips #1 screwdriver.
-
Completely remove the motor housing from the plastic.
I found the repair easier to do with the motor still attached to the housing, step 15-16 unnecessary.
-
-
-
Turn the device around, and remove the three screws attaching the left most motor to the metal backing using a Phillips #1 screwdriver.
-
Completely remove the motor from the metal backing. This will make it easier to move around when replacing the optical encoder.

Remove the white 5-pin adapter from the end of the optical encoder.
-
Remove the plastic casing by prying it off with a screwdriver or a plastic opening tool.

Remove the two silver screws from the underside of the optical encoder with a Phillips #0 screwdriver, and the circuit will be free from the motor and ready to replace!
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.

During reinstallation make sure when doing this step to align the stop on the wheel gear with the track as shown in the second and third pictures.
-
Also make sure that the metal half-circle clip is placed properly inside the slot.
-
After placing the metal clip in the slot, place the plastic cog on top of the clip and on the 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.

!!!!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…
Sylvain Jn - 답글
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?
