Got a replacement laser for the Beocenter 9300 and now trying to replace it, but cant for the life of me figure out how to get the old laser module out.



To me it looks like I have to remove the big white gear to be able to lift the guide rail and the laser module out. But I can't make the gear move out, and a little afraid to break it.

Any inputs?

Thanks in advance

And use ESD-protection!
These things are highly sensitive to static electricity.
Many owners experience that new lasers don't work, - and while it is correct that
many asian "counterfeits" won't work, or only work for a few hours, many lasers
are damaged by static electricity, - either during shipping, if shipped without
shorting clamp and/or ESD-shielding or by handling without taking
proper ESD-precautions.
I have seen many of both cases.

Hi: Watch this video Go to 5:45 mark. Derek
Hi and thanks for the video link. It seems though that on the unit he is working on in the video he is removing a plastic bracket which gives acces to the other guide rail. But on the on from the BC9300 that both the guide rail and the overhanging bracket" is part of cast metal, so there is no way to get the laser module up in that side of the mechanism. As I see it the only way is to remove the white gear, but I am very open to other suggestions

The white gear wheel is just snapped on the axle. Either pull it or use a small needle to open the snap...
