    seconded, please add the 3 “missing” screws into the guide. Almost started to try and pry the cover off with prying tools.

    • Flip the device over and four 15.6mm screws with a Phillips #1 screwdriver.

    • Pull the lower clamp up and out of the shifter assembly.

    The screws on the far left and right are too tight! What do I do?

    • Remove the two 10mmm hex nuts with a 10mm socket and a ratchet.

    • Next, unscrew the clamps by holding the lower portion of the shifter and unscrewing the top part.

    • Also remove the nut on the screw if it wasn't removed with the lower clamp.

    • Remove the eight black 11.9mm screws from the bottom housing with a Phillips #1 screwdriver.

    • Carefully lift the top half of the housing from the bottom.

    • Watch out, there are 2 wires attached to the PCB board. Be careful not to damage these in any way.

    I was completely unable to seperate the top half from the bottom, and that’s with my prying at it with screwdrivers and flatheads for about 20 minutes. There are absolutely zero screws visible from the bottom so i don’t know what that’s all about. Any thoughts? other than the fact that the plastic is disfigured forever.

    After you remove the shift knob and the leather, three more screw holes become visible. You need to remove those as well (which this guide conveniently doesn’t mention).

    • Carefully remove the two plastic connectors with a plastic opening tool or your hands.

  9. Logitech G27 Shifter Potentiometer Replacement: passo 9, immagine 1 di 1
    • Go to the lower portion of the shifter; remove two black screws and four silver 15.9mm screws with a Phillips #1 screwdriver.

    • There is grease covering the whole shifting assembly so it will get messy when removing.

    • Squeeze the two metal plates together and slowly pull up. The assembly is spring loaded and will fall apart if it is not squeezed.

  11. Logitech G27 Shifter Potentiometer Replacement: passo 11, immagine 1 di 2 Logitech G27 Shifter Potentiometer Replacement: passo 11, immagine 2 di 2
    • Remove the shifter assembly and place it on a flat surface. Then remove the metal plate with the spring and ball bearing attached.

    • This is the hardest part of reassembling. Make sure to properly place the spring inside of the inner housing and the ball bearing on top. Place the other metal piece on top of it.

    • You will now have access to the two potentiometers on the sides of the assembly. Make sure they are properly connected and if need be, replace them by removing.

    Anyone knows what type of potentiometers these are? I haven't been able to source them for years now.

    The light brown circuitboard is for the down spdt switch to detect reverse

    Matthew Adler - Replica

    Where do you get replacement potentiometers ? , Iv not taken mine apart to look yet , but reverse no longer works on my shifter

    bertovzki@hotmail.co.nz - Replica

    Weet iemand waar ik de achter draadjes voor de achteruit kan vinden. Wil er een handrem bij solderen.

    Zal dat mogelijk zijn denken jullie

Where can I buy replacement pots?

Riccardo Flask - Replica

Great guide, thanks a lot for the effort. It turned out that one of the cables connecting the pot to the pcb had snapped. Just going to test now.....fingers crossed. :-)

Cheers. Andy M.

Hey did It work?

Levente Gergely -

I didn't even have to replace them. Only cleaning with electronic cleaning spray and move the pots fully was enough to fix it. However, and I think that was the real problem, one of the pots was damaged because the plastic pointer it has to be inplace in the assembly was broken. Only one half was in place. I used something here we call "type cleaner clay", some sort of clay not use to play but to fix things to the wall or clenaning old typewriters. Comonly blue. Other forums says damaged pots are not common, only dirty or may be, as mine broken. Easy to fix

Ricker Silva - Replica

Has anybody found a source for these pots? I'm guessing they're proprietary? Possibly some version of CTS 252 series? Anything they can be replaced with? I've worked on a couple of these where people opened up the shifter pots trying to clean them and damaged them, and I cannot for the life of me find any replacements and I've searched high and low through every joystick potentiometer source I could find.

David Riley - Replica

if the potentiometer is broken do the other buttons on the shifter still work?

bradhunt1 - Replica

Hey do you know where I can get these piece for spare?

Thanks

Jennifer juarez - Replica

Oh no! I do not know where to draw the spring.

valtsuhoo - Replica

Could this fix my shifter problem? First and second works fine but 3 recognises it as 1. 4th recognises as second fifth as first sixth as second and reverse is first. Could this fix it?

Levente Gergely - Replica

I had the same problem you have. I removed both pots and putted them in a cup of petrolum solvant (i used kerosene) for few minutes then put them back and the problem gone. Try to use cable tie before u bring the mechanisim out of its place so it will be easy for you to do the job.

Zeynep Cruze -

this worked for my shifter too. i got the newer one as to date, the one thats for the g920. let my lil brothers friend use it, they hit it hard and gear one did respond, but kept going to neutral, when checked in devices and printers, the button was flickering a lot. the process was not exactly the same but most of it is. when in doubt, unscrew everything anyway. I accidentally put the metal ball into where the spring was supposed to be, it got stuck. I got a drill and drilled a whole on the side behind where i got the ball stuck. that did the trick. thanks m8, ma shifter works again

Do I need to buy new potetiometers? Cause I cant find any, or do I just need to remove them and place them in again?

PiG_Be4sT - Replica

Where can i buy new potentiometer such as the original one’s?

CreepyPic - Replica

Does anyone know what kind of JST connector that is that connects to the Potentiometer? the cable of mine snapped right infront of the port and i have no idea which JST connector they are preferabbly with the Cable connected so i can just solder them together.

Is it worth it to buy a G29 shifter and just replace the whole internals/potentiometers and connect it to the main pcb , not the g29 shifter’s pcb?

robin2012 - Replica

I am having a problem with the potentiometers and cleaning won't work, can you direct me to somewhere I can buy new ones
