Usually oil moving parts but should not be required unless used for many hours!
Screw should go straight in without a nut!
SOURCE: bobbin doesn't fill in bobbin winder
The bobbin winder question is a frequent one and it is very easy to solve. If you look at the shaft where the bobbin sits on the bobbin winder, you will notice that it has a slot in the middle of the shaft, an opening if you will. This is where you use a flat screw driver and open that space more to give more friction to the bobbin so it is not loose on the shaft. That slot was made for that. There are different bobbins on the market so thats why the slot is there. If it is too tight, grab a pair of pliers and close the gap. The metal of the bobbin winder on that shaft is malleable exactly for this reason. No need to put plastic bag material or anything like that. Use it as it was intended for.
SOURCE: bobbin casing not in sync with needle.
When you have that hook drive gear back out turn the wheel until the needlebar is in its highest position. The bar with the teeth that the gear fits onto should be all the way to the right. Now slide the hook driver gear back on. You can lay the hook back in and slowly turn the wheel. Watch that the point of the hook on its upwards stroke is coming slightly above the eye of the needle. When it does this you will be in the correct position to put the screw back on.
Hope this helps. It may take a couple of tries but you will figure it out.

it sounds like the needle hook timing is out. You need to get the needle in the lowest position and measure the gap from the needle to the hook point on the bobbin shuttle. It should be 1/4". You will need to remove the foot and foot plate to be able to see. I use a 1/4" drill bit as a gauge. If you need to adjust it, you will need to remove the free arm cover to the right of the foot and loosen the 2 allen head screws that hold the drive gear. Adjust the gap, tighten the screws and retry. Usually if the needle catches the thread to early, it will make a bad stitch and the upper thread will break. If it catches to late, it will make thread loops and the machine will skip stitches. Good luck, these are a good machine and worth fixing. Phil

When you have the winder rubber on try and turn the winder by hand, if it does not move the chances are the winder has seized, if the winder wheel is moving but not the spindle then the grip (thread) has worn, if you cannot move the whole winder by hand and it has seized you need to get some WD40 and spray a few drops down the spindle, take an electric drill and put it over the top of the spindle and switch it on slowly and it will probably free it off, be aware of oil splashing out.
