DIY: Fix a Broken Sewing Machine
Do you want to save on repairing your sewing machine? Fix your sewing machine problems by using these instructions and tips.
To find a malfunction and fix it, is needed often have to disassemble the body of sewing machine. To do it you need have the tools: at least two types of screwdrivers (phillips screwdriver and flat).
For this article, I used an ordinary entry-level sewing machine with an oscillating shuttle hook.
How to disassemble a front cover
At first unscrew this screw with a flat screwdriver and remove the front cover.
In this compartment there are mechanisms of needle bar and presser foot. All these knots are made from metal and therefore are reliable.
Most often this lid is removed to replace the bulb or to oil the bushings and the needle bar.
There is another case when you need to remove the front cover. The arrow on the photo indicates the screw holding the needle bar.
To oil the needle bar is needed 1-2 drops of oil, no more. Note: The oil in this place can get on the fabric during sewing and spoil it.
Note that the bushings have special oil holes.
Sewing machine shuttle hook
All parts of the shuttle hook device must be clean and smooth. Rusty or dirty places may be cause of bobbin thread bunching, looping and tangling.
The needle plate must also be in perfect condition, especially the slit hole. Metal notches appearing from needle strikes will lead to the thread breaking.
Periodically remove the needle plate and clean the shuttle compartment with a stiff brush.
How to disassemble the body of a sewing machine
Start disassemble the body of a sewing machine with removing the plastic knobs (stitch selectors). Just pull them on yourself.
The position of the handle has only one position, so it will be easy to put them back.
Many screws are hidden inside the case and can be detected if you remove the plastic plugs.
When all the screws are inverted, you need to separate the two halves of the case.
Note: In addition to the screws, they are held by means of latches also.
Look inside the shuttle compartment! Here you can find also a screw holding the back half of the body of the sewing machine.
Delete this screw and carefully using the knife or flat screwdriver continue open the shell halves.
When disconnecting the halves of case is needed to lower the presser foot lifting lever.
It is especially difficult to remove the back cover in the place of the electrical cord connection unit.
I took off only the back of the case. To remove the front half does not make sense, because this sewing machine works properly. My task is to show you what can break down the sewing machine and how to fix it.
The most difficult breakages of a sewing machine
A plastic detail is also in the shuttle device.
Observe the recommendations that are in the instruction for your sewing machine!
The drive belt is an important part of the sewing machine. Years later, he can be breaking. If the sewing machine motor is running and the machine not move the fabric, then most likely it will be necessary to change the drive belt.
Note: This can only be done at a service center.
The electric motor rarely fails. If the sewing machine does not respond when the pedal is pressed needs check sewing machine electric motor.
But notice that not only the electric motor may have broken down. Another reason may be the foot control pedal and the cords that are connected sewing machine with an electrical outlet.
Now the last tip. Never disassemble the case of your sewing machine. In addition to the fact that it is difficult to do this, it can also lead to a breakdown your sewing machine.
In any case, you will not be able to assemble the halves together without a trace.
