Dear guys,

the problem you mentioned is caused by the motor encoder wheel.

If you open the G25 you'll see a small black plastic box on the rear of the right side motor, inside that box there is a PLASTIC encoder wheel mounted on the motor shaft.
During the normal use the motor shaft gets hot and as the time pass by, day by day, the encoder wheel stands a hard wear and tear 'cause it is gripped on the motor shaft (the wheel hole is precise to the shaft diameter to get it blocked)
At a certain point, the wheel gets a crack on its radius (due to the wheel grip on the shaft + heat) preventing its normal rotation on the shaft.

Yes, it's a pain in the ass 'cause it's a lack of Logitech project department.

The solution is to remove the broken wheel, get it fixed with a drop of instant glue and then try to enlarge the wheel hole using a 3.5mm drill bit rotating it BY HAND very very slightly (don't try to use electric dril or you'll get a pulverized wheel!)

Then, at job done, fix the wheel on the shaft again using the same instant glue (ONE DROP!) directly on the shaft and then insert the wheel at the right position and leave it at rest about 20 sec.

Re-assemble the small electronic board and then close the box.

Now your G25 should be fine again!

If this does not fix your issue or you manage to break the encoder into pieces, the answer to your prayer can be found at http://cmlaserservice.com/ This company makes a BRASS replacement optical encoder wheel for the G25/G27. It is $37 (via PayPal) shipped from Thailand. It will take a week or so to get it so be patient.

Selling my G27..as title states. The only reason I advertise here is because selling locally or on amazon isnt happening.

My name ” in game” is SEi, some of you might remember me, anyway, im letting it go for $200.00 even. I will take care of shipping and handling.

I just need it gone, condition is excellent and the motors are strong as an ox. Pm me for pics and we can go from there.


Thanks.
