How To Disassemble A Sewing Machine.
One of the most time consuming parts of any sewing machine repair is the disassembly. On many machines this is as simple as removing a few screws, but on other machines it can be a bit more complicated.
Many of the newer machines use a snap fit system that requires the technician to find the snap points, and release them by pressing one side of the cover in while the other remains rigid. Unless all the appropriate screws have been removed and the proper order followed, removing the covers can be quite frustrating.
Keeping your parts including screws well organized is essential. Otherwise, as you reassemble, you will find extra screws and the covers may not align. For this reason, be sure to keep covers with their correct screws. If necessary, tape the screws in place temporarily. The more complicate the machine is, the more important organization of parts becomes.
Disassembly should proceed from right to left. Remove the tray, the lower arm cover, and the needle bar cover. Remove the needle, needle plate, bobbin carrier or case, and the hook cover and hook. Begin removing screws across the back from right to left. Remove any other screws as needed from hand wheel side, and bottom of the machine.
Once the covers have been removed, proceed to brush and blow away debris. Use solvent to dissolve old lubrications. Use pure clean sewing machine oil, and place one drop everywhere metal touches metal.
Notice this Brother XL sewing machine has an oscillating hook system. You can see the bracket for the hook inside and the race outside.
