Steps for replacing sewing machine gears:
To accomplish any task, you, surely have to follow certain steps. So to replace the defective gears with the new ones, you have to lift the sewing foot with the help of sewing wheel. You need to take the foot off which is fastened with the help of screws.
Just loosen up the screws and remove the foot. Next, you have to remove the needle plate and bobbin. If you remove the whole bobbin case then it would be much better but it is not necessary. You can do it otherwise.
Putting the Machine Upside Down:
As you are done with the above-mentioned steps, what next you have to do is, to put the machine upside down. Usually, gears are fixed on the bottom side of the machine but it is not necessary.
You might have a machine in which the whole system is fixed on the upper side as it depends upon the type or company of machine you are using. There is no hard and fast rule for this. So in machines, which have their machinery in the bottom case, you need to disassemble the bottom part of the machine
Disassembling the Machine:
Here, the most important point is that, whenever you are going to disassemble anything, especially a machine, you need to have appropriate tools for that. If you try to loosen up the screws with the wrong tools and try hard on them, you would surely lose your machine.
Loosening the Screws:
Next step for replacing the gears is to take off the bottom cover by just loosening the screws. Another important point is that you need to keep all the screws with their respective parts so that when you try to assemble them out, you don’t face any problem.
Locating the Main Shaft:
As you are done with taking off the bottom cover, the next step is to locate the main shaft on which the gears are fixed. Loosen up the shaft by removing the screws fastened to it. You can do this with the help of a screwdriver or an Allen wrench, depending upon the type of machine you are operating.
You might have different types of machine or they might be manufactured by different companies, so what is important is that you need to locate the particular parts which I have mentioned in this article and work on them. Don’t get confused with the position of those parts!
Freeing the Gear:
Moving to the next step, you need to move the shaft towards right up to a distance until the gear attached to it gets free. There might be a small clip attached with the shaft, so you need to remove that clip before moving it otherwise it won’t move. Again, it is a reminder to keep all the disassembled parts safely because it would be problematic if you lose any part of it.
Replacing Old Gear with New One:
Loosen up the screws of gear and replace the gear with the new one. The number of gears fixed in the machine depends upon the type of machine you are using but here is a piece of advice that even if only one gear is defective, you should replace all the gears for the sake of better working of the machine.
As you are done with replacing all the old gears with the new ones, the next step is to be to reassemble the parts. Put all the parts back in their positions and fasten them with their respective screws. Don’t place them in the wrong positions!
Checking the Replaced Gears:
Next, you need to check that whether the replaced gears are working well or not. If your machine is not working properly, then it doesn’t only mean that the problem is with the gears. The problem can be with the other parts which you disassembled before and haven’t fixed them properly. So it is very important to fix all the parts back in their appropriate positions, otherwise, it would be much problematic.
