Sticky mouse wheel on Logitech M570 Trackball

Repair of Trackball mouse and cleaning of sticky rubber scroll wheel.

[@braziliantvhd2768]

Mine wouldn't scroll at all but had nothing to do with dirt or being sticky. I opened it up and notice the wheel sensor was bent, so I re-bent it to point at the scroll wheel and also cleaned the sensor head with q-tip and alcohol, it worked fine. I think I may have bent it replacing the left click switch a several months earlier, or dropped it.

Also, while mine was apart I cleaned the decoder. This way it does not skip when scrolling up and down. The decoder is on the side of the wheel, (part of the wheel). Look with a flashlight and you will see it. It looks like the wheel with LOTS of spaces on it. Sometimes junk gets in there too. Also, wipe down the part on the board next to the wheel itself.

Thanks so much. I had the same problem with the same trackpad and yes it had been stored for a while. Worked perfectly
