Re: put back togather

Well I did it. It's not exactly easy to describe. I accidently took mine apart trying to clean the roller ball and out popped the 2 springs. I sort of put it back together in "reverse". In other words, I put it together without the scroll device and then looked through the hole. By doing this, I figured it out -- when you know it's simple but to describe it without pictures is almost impossible. Mine works fine now but I don't know how to help you.

I've taken apart and cleaned our logitech BJ58 optical mouse and there are 2 spring like components that have escaped and I just need to know where to put them back. My husband is going to kill me lol ;)

If they are springs, they probably go under the buttons somewhere.

Go buy him a new one that looks like a racing car with flashing lights, he'll just think you love him.

The Spring goes on the right side of the mouse wheel as it would be pointing at your computer. It supports the wheel to make it spring back when preasure is applied. Place the spring on the axle with the spring forming an spread out "A" (not a "V"). You will see that it falls nicely into the 2 little tower mounts. my real problem was with the other little piece of bent wire that fell out. This is the part that makes the snaping fealing as you scroll the wheel. This connects directly on the plastic part that is mounted on the scroll wheel. If you look at that plastic part you will see a small hole. One end goes in that hole & the other rounded end goes to the splines on the wheel itself. I hope this helps, it better that just saying go buy another.

Cant get it back together

I put together what I knew where it went, the put the whole thing together and looked at it before putting in the screws. I saw a hole and remembered a "button" there that moved sideways with a spring pushing it back into the original place. I reopened and after examining the part put it in that slot. I then put it together and it worked. I put the screws back in then and all is well
Thank you for the reply.
Glad I found your site. I will keep it if I ever need any help.

Microsoft Wireless Optical mouse 2.0 Sticky central wheel

I just took mine apart to fix same problem, works much better but not sure for how long.

Quite simple to dismantle the unit.

Take the battery cover off, remove batteries.
There is a small screw in the middle of the battery cavity, you will need a very small Phillips head screwdriver.
Gently ease the base (holding circuit board) from the top shell
The wheel unit can be gently eased out of its cradle, use the small screwdriver to pop it out, watch out for the small spring between base and wheel unit, don't lose it
You can disconnect the wheel unit from the circuit board by unhooking the small plug connector

Now defluff, then clean the wheel - I used a tiny amount of turps on a cloth, anything similar should work. If you look closely the reason the wheel won't roll smoothly is that the gel ring on the wheel is too close and rubs at the front and back of the cradle. Once grime builds up, this problem makes the wheel unusable. Roll the wheel back and forth along a clean surface once cleaned, should start rolling freely again.

I also unscrewed the top shell from the mouse buttons (all one piece, pinch the plastic pegs in the centre of the shell together to release) and cleaned the whole unit up before putting it back together

Don't forget the spring when putting the wheel unit back. When screwing the base to the top shell make sure there is no play between the two parts before you put the batteries back in, mine was a bit tricky to get tight again but worked fine second attempt
