Trackman cordless spring associated with the scroll wheel

The ball in my trackman was very loose so I opened it up to take a look & the wheel mechanism feel out. I have a problem with a small spring that attaches somehow to the wheel but can't figure it out. I can get it back together & it works but the wheel moves freely, no clicks. Anybody help?

Re: Trackman cordless spring associated with the scroll...

OK this is a little hard to describe, but I think my son and I figured it out. The spring has sort of a loop at one end and a square tail at the other end. The loop end fits inside the wheel then the spring follows the channel in the plastic. Finally, the square tail goes underneath into a hole in the plastic piece. I wish I had a photo but my camera broke!!

Logitech trackman wheel stopped working. I have changed the batteries and reset, but the problem persists. Can you help?Thank you, Claudia

First step would be to clean the sensor inside the ball housing. Remove the ball (turn retaining ring on bottom or simply pull out) and clean the sensor area free of debris or dust using cotton swabs or klenex. Next step would be to ensure that you have have no wireless devices such as a cordless phone or wireless routers in close proximity that may interfere with the signal. Finally, test on another computer to see if you gain functionality else it may be time to find a new mouse.

Trackman wheel....ball fell loose, now actin weird

Dust has a tendancy to collect under the ball at the 3 contact tips (you should look under the ball)and it is possible enough dust collected when the ball was removed, that the dust particles became a large dust ball and lodged under the ball making it impossible to move!
Remove the ball and clean the area and replace the ball and it should work fine.

TrackMan Wheel Trackball Spring - where does it go.

it's not really a spring -- it's just a twisted piece of wire. actually, it's what makes your little scroll wheel click when you turn it. place the scrool wheel in the little plastic bracket that holds it with the longest piece of axel (hollow side of wheel) in. then TURN THE BRACKET OVER. the wire goes on the BOTTOM, which is quite counterintuitive. you'll see how it goes -- the smallest end of the wire goes INSIDE the scroll wheel and the kinda squared end of the wire goes into a little hole in the bracket. you'll understand when you look closely at it. once the wire is installed, hold it in place when you turn the bracket/ball/wire assembly over. fit the legs on the bracket into the groves on the base of the trackball -- that's the side where the ball sits and the circuit board is. make sure the scroll wheel passes through the trackball cover when putting it all back together. VOILA! problem solved.
