    • Switch for this is on the bottom. Very findable, so no image.

    • And the Unifying receiver, if its in the mouse. This is not strictly needed, but you shold probably still do it.

    • They are hidden below the two glide pads on the sides of the release switch for the battery cover. Just stick your Phillips in there and get them out.

    • It will resist a little, gently pull. When you have a little gap, gently rock it for- and backward a little, until it gets loose.

    • The second image tries to show the clutches that hold it to the upper cover.

    • To remove the scroll wheel, pull straight upwards, taking care the spring on the bottom stays intact. There is a plastic guide on the front of the clear housing that sits between the two plastic posts at the front. Make sure this comes straight up/down to release.

    • On my mouse, the rubber on the scroll wheel started to disentegrate. (No photos) but basically, touching the rubber would leave a black streak on your finger. The inside of the plastic housing was also black.

    • In addition to other debris, this caused the scroll wheel to stop working entirely, because the wheel registers scrolling by shining light through the clear housing through to the other side. You'll notice there are "fins" inside the wheel; the interruption of the light by these fins is how the mouse registers scrolling.

    • By placing a little outward tension on the center spoke, you can remove the wheel to clean the housing. Be careful not to lose the arm and the spring at the rear of this assembly.

    • In my case, the rubber/glue was so disintegrated that the "tire" / wheel cover would not stay centered and kept leaving marks. So I just got rid of it. You could place a thin strip of duct tape or something else if you wanted a cover, but there's no real need for it.

    • I decided to photograph this after I had reassembled it. I would recommend you do this assembly before placing the scroll wheel back onto the logic board.

    • Reassembling the scroll wheel:

    • With the recess pointing to the left mouse button, line up one of the hubs and push the other side until both center hubs lock in place.

    • Then, place the haptic feedback arm in place by inserting it into the recess, and lining up the left of the two locking clips at the rear of the plastic housing and clipping it in place. Leave the right side unclipped at this point.

    • I found it easiest to insert the spring at this point.

    • Compress the spring so that it sits entirely underneath the arm. (See photos #2-3)

    • After a few tries, I was successful by compressing it with a paper clip, prepared as shown in the next step. But anything will do the job. The important thing is that it's small enough to allow the right side to click into place while the spring is compressed so the arm sits entirely above the spring.

    • Prepare the paper clip spring compressor (optional) by unbending the end of a paper clip 90º.

    • With needle-nose pliers, grab about 1/8" (red) of the end in your dominant hand. Further below, use channel lock or vice grip pliers (with a wider face) to stabilize (blue).

    • Holding the channel lock (blue) pliers in place, bend the end in half (90º) and then in half again. Then, use the flat part of the needle-nose pliers to compress this fold unto a tight U-bend.

    • As shown in the second photo (but prior to reinstalling the housing to the logic board to avoid damaging), compress the spring with the left side of the arm clipped in place, but the right side not yet clipped in. Once the spring is compressed, the paper clip is thin enough that you can click the other side of the arm into place.

    • The small bend in the arm must sit entirely on top of the spring.

Very nice! Helped me get mine back together after I accidently removed the wire on the wheel.

Clear and concise, very helpful ! My wheel click didn't work anymore, a quick dusting and cleaning of the insides got it back to normal.

To those who would like to take the logics board from the lower casing : be careful when puting it back together, as the on/off switch under the board must properly align with the small moving plastic piece located in the lower casing. Otherwise, you might have to disasemble the whole thing again just to put it right.

Very helpful! my problem was the Rubber of the wheel, it has “expanded” and it made some friction with the transparent structure. Disassembled, rolled on a flat surface pressing hard and the rubber no longer touches the plastic! Awesome!

Thanks! I’ve managed to clean one of the mouse buttons, so it saved me from buying a new one.

Great guide with helpful pictures. I cleaned the mouse wheel by dampening a strip of tissue paper with alcohol and using a flathead eyeglasses screwdriver to get it started wheeling through the housing.
