If the bobbin winder spindle is loose and flopping around in the opening in the front of the machine is has come out of the frame that it should be mounted in. Operating the machine with loose parts inside can be risky for the machine and the operator.
Don't take a chance on causing further damage to the machine. The bobbin winder can be replaced without too much trouble and is relatively inexpensive.
If the pin is in the center of the winder, great. But, it will come out again sooner each time you put it back. If the pin isn't still in the center of the spindle, and about 40% of the time it is not, it is loose in the machine. You can still remove covers, put it back, use it for a while and then it falls out in the middle of the next big job you have with a time crunch. Fix it right the first time and forget about it.
The bobbin winder is held in place with a pin. If the "o-ring" on the edge is ok, just take a thin object and push the pin in the center of the bobbin winder back in it's mounting hole (jiggle around to find the mounting hole). Then push a little more to secure it (friction fit). I discovered this after taking both back and front covers off!!!
The "trip" for the bobbin winder has serations on the mounting post, so it can be pulled off and rotated slightly to adjust how full the bobbin gets.
If the pin happens to be in the center, push it back in, but don't push too far or it won't work. About 40% of the time the pin will not be visible in the center of the spindle meaning it is loose inside the machine. Now remember, it will pop out again sooner each time you push it back in until you replace it and you never have time to stop and put it back in during your project. Just fix it right and be done with it. A new bobbin winder for this machine will last longer than the original as long as you get a genuine part from Husqvarna.
I am not sure if I understand your question. You mention the bobbin assembly. This could be interpreted as the bobbin basket in the hook area or as the bobbin winder on the top of the machine. You asked how to take the cover off the machine. If you need to remove the bobbin basket the cover slides off above the bobbin then slide the needle plate forward. You can now remove the U shaped grey retainer and extract the bobbin basket.
If you want to remove the main covers there are #10 torx screws on the back and 4 #25 torx screws on the bottom. Do not remove the inside screws only the corner screws and the ones furthest from the corners. The needle threader needs to be in the lowest position and is held by the needle clamp screw. The bobbin winder needs to be in the low position too. The front and rear housing clam-shell together with hidden clips. The next part is scary you slap the machine in the correct places and the back pops off. I do not recommend trying this at home. It is also important when working inside your machine to wear a ground strap and ground the frame to prevent static electricity from damaging the computer chips. After the rear cover is removed there are 2 more #25 torx screws that hold the front cover on, and another #10 torx near the tension assembly. As stated before you may do more damage trying to work on this without proper training.
Today I repaired 7 sewing machines. as the parts are removed I place them in lettered bins. It saves me lots of time when putting it back together to have the parts sorted and lettered. I bill customers at $50/hour. When someone brings us a machine half apart and a basket of screws it usually costs them more than if I did the work to begin with. We have a term for this we call them basket cases.
