Introduzione

Se il tuo Logitech G27 non risponde correttamente, anche dopo averlo calibrato, potresti dover sostituire il suo codificatore ottico. il codificatore ottico è un piccolo dispositivo elettronico che trasforma la rotazione del volante in un segnale elettrico che il computer può capire. Non è troppo difficile da sostituire: ti serve solo molta pazienza poiché dovrai svitare un mucchio di viti! Assicurati che il tuo volante sua scollegato completamente prima di iniziare questa procedura.

  1. JFe3hZpcNcMwfMMY

    • Svita le sei viti grigie esagonali da 25 mm con una chiave a brugola da 4 mm.

    • Stai attento mentre sollevi il volante, in quanto ci sono dei cavi delicati collegati alla parte inferiore.

    • Solleva attentamente il volante, ma non scollegarlo dal resto del dispositivo.

    • Svita le due viti argento che tengono ferma la scheda PCB nel volante con un cacciavite a croce Phillips #1.

  4. foUkt5y4AwJkc2ET

    • Rimuovi attentamente la scheda PCB dal mozzo del volante.

  5. Qtmlc6TkePtrVyam

    • Schiaccia e scollega attentamente il connettore largo a 7 pin sotto la scheda PCB.

    • Stai attento mentre scolleghi questo adattatore: cerca di non tirare dai cavi per evitare di danneggiarli. Invece, fai ondeggiare il connettore in plastica mentre lo tiri per rilasciarlo.

    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..

    Alexander -

    @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 Akgül -

    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!

    • Puoi ora rimuovere del tutto il volante dal mozzo. Mettilo da parte finché non rimonti il volante.

    • Svita le tre viti argento da 37,5 mm più interne con un cacciavite a croce Phillips #2.

    • Rimuovi il mozzo del volante e spingi il connettore attraverso il centro del mozzo.

  7. hRAYY1mMrAVKZJFD

    • Puoi ora mettere da parte il mozzo e girare la copertura del volante per scoprire la parte inferiore.

    • Svita le otto viti argento da 15,9 mm tutto intorno sotto la copertura del volante con un cacciavite a croce Phillips #1.

  8. UidVkwPtGC2eJLMK

    • Ruta la copertura a testa in su e rimuovine la metà superiore, svelando la maggior parte dei componenti del volante.

    • Puoi mettere da parte la copertura del volante finché non lo rimonti.

    need two new black screes abouve the pcb board.. lost them need to know the size since the screws i replace it with was not exact..

    Alexander -

    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.

    • Svita le quattro viti argento da 7,3 mm che fissano la scheda PCB verde alla copertura del motore con un cacciavite a croce Phillips #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.

    Oula Kuuva -

    For removing C-Clamps steps 9-13 are unnecessary.

    • Scollega i tre connettori in plastica sulla parte sinistra della scheda PCB.

    • Scollega i due connettori in plastica sulla parte superiore della scheda PCB.

    • Scollega i tre connettori in plastica sulla parte destra della scheda PCB.

    • Tirare i connettori in plastica richiede parecchia forza, ma stai attento e non tirare direttamente sui cavi. Cerca di fare leva o tirare il maschio del connettore.

    • Se ti serva una leva aggiuntiva mentre scolleghi questi connettori, prova ad usare uno strumento di apertura in plastica.

    • Scollegare questi connettori permetterà un accesso più semplice alle quattro viti che fissano il supporto della scheda PCB alla copertura del motore.

    Some of the connectors have locks on them, I would recommend this as a two person job.

    Reuben Andrews -

    I didn't take them off :)

    Evaristo Rivieccio Vega -

    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.

    • Rimuovi la scheda PCB dopo aver scollegato tutti i connettori in plastica.

    • Puoi ora metterla da parte.

  12. Hvf5BHMD5r3wZDec

    • Svita le due viti nere superiori da 12,3 mm con un cacciavite a croce Phillips #2.

    • Svita le due viti argento inferiori da 15,5 mm con un cacciavite a croce Phillips #1.

  13. q4XLbMAPFVVY2XSU

    • Dopo aver seguito la guida prerequisita, gira a testa in giù il tuo dispositivo.

    • Svita le quattro viti più al centro dalla parte inferiore del dispositivo con un cacciavite a croce Phillips #1.

    • Gira il tuo dispositivo a testa in su e rimuovi del tutto la copertura del motore dal resto del dispositivo.

  15. ta5DsYr1cnKZe14M

    • Svita le otto viti che fissano la copertura in metallo del motore alla plastica con un cacciavite a croce Phillips #1.

    • Rimuovi del tutto la copertura del motore dalla plastica.

    • In questa immagine, il codificatore ottico è attaccato all'estremità del motore a destra. Ha una copertura in plastica nera per proteggerlo.

    I found the repair easier to do with the motor still attached to the housing, step 15-16 unnecessary.

    • Gira il dispositivo e svita le tre viti che fissa il motore a sinistra alla protezione in metallo usando un cacciavite a croce Phillips #1.

    • Rimuovi del tutto il motore dalla protezione in metallo. Questo semplificherà lo spostamento quando sostituirai il codificatore ottico.

    • Scollega l'adattatore bianco a 5 pin dall'estremità del codificatore ottico.

    • Presta la stessa attenzione con questo adattatore come per tutti gli altri: non tirare direttamente sui cavi e fallo ondeggiare per scollegarlo.

    • rimuovi la copertura in plastica facendo leva con un cacciavite o uno strumento di apertura in plastica.

    • Svita le due viti argento da sotto il codificatore ottico con un cacciavite a croce Phillips #0 e la scheda sarà libera dal motore e pronta ad essere sostituita.

    • Stai attento a non piegare la luce o il ricevitore nero che sporgono dalla scheda. Se non si allineano, il tuo volante non sarà in grado di calibrarsi e sarà difficile riallinearli.

    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?

    Jackson Beers -

    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.

    • Durante il rimontaggio, mentre esegui questo passaggio, assicurati di allineare il fermo sull'ingranaggio del volante con il tracciato come mostrato nella seconda e terza immagine.

    • Assicurati anche che il gancio semicircolare in metallo sia posizionato correttamente nel suo alloggio.

    • Dopo aver posizionato il gancio in metallo nell'alloggio, posiziona l'ingranagio in plastica sopra il gancio e sul tracciato.

    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.

    Philipp H -

    There is also small dot on the gear and small arrow on the track that represent the middle, I would say that this is more accurate method. (on G25)

    Vojtěch H -

    There is a Timing mark on the face of the linear gear and the round gear, line the timings dots together

Where can you get the encoder to replace it?

invertig0 -

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.

Georgios Arkouzis -

Very much appreciate your assistance & time putting this together. I Chose the expoxy route. My wheel IS BACK!

Dave -

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.

robertleskovsek -

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?

felipezerobala -

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 :-)

Gracias a esta guía he podido reparar el volante G27. Muchas gracias.

urrielu -

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.

SouthernPotato -

Hello, i repaired the old optical encoder. Now when i connect my wheel to PC the calibration works. But then PC doesn't "read" when im stearing. The other buttons are ok. Please help me what to do. Thanks

Tom Bubok -

can you please share me the motor specifications?

Gokulraj S -

Is this questin for me?

Tom Bubok -

yeah ! I need this motor specifications :)

Gokulraj S -

Repaired with this guide, thanks.

For the repair of the optical encoder I used a washer.

smigolxp -

not encoder?? Washer??

Il Vloggatore -

is it work sameway??

Il Vloggatore -

I user a washer to repair the broken optical encoder.

smigolxp -

Excellent guide and thanks for the publication and your help !!!

Luca Ragno -

!!!!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 ;)

laikros -

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

Mister -

Also I have managed to change the encoder without disassembling the mainboard and bearing housing. Just remove the motor encoder cover and change the encoder. The same way worked on Driving Force GT

Mister -

Where can I order the optical IR sensor? I’m not getting my drive on without one …

DieCalmerThanASuicideBomber -

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 -

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..

Don H -

how many slot encoder do i need?

Nico Rosella -

Step 15 and 16 can be skipped! You can keep the motors attached to the frame to open up and replace the encoder wheel. (I just did it like that and that works fine)

Don H -

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

DeadShoT World -

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?
