How to disassemble the motor of a Janome sewing machine. Installation and repair of a Janome sewing machine. B. Removing the side cover
A sewing machine is the main working tool of a needlewoman. In order for it to serve for a long time and not cause trouble in operation, it is necessary to carry out the adjustment, cleaning and lubrication procedures in a timely manner. This is usually done according to the attached instructions, which must always be kept next to the device. After this, all the parts begin to function more harmoniously, and the work process is a pleasure. All the subtleties and nuances of how to lubricate a Janome sewing machine are presented below.
Why lubricate
If you do not clean and lubricate your sewing machine in a timely manner, it may fail. Namely:
- parts will begin to creak;
- noise will appear;
- the threads will break;
- the seams will become uneven and tight.
To prevent this from happening, you need to know how and where to properly lubricate your Janome sewing machine.
This is necessary for:
- long service life;
- neat stitches;
- getting an easy ride;
- ensuring a smooth ride;
- easy settings.
What do you need for work?
To carry out the procedure at home, you will need:
- 100 g of machine oil for lubrication (can be purchased at a specialized or hardware store);
- medical syringe;
- a special brush for removing dust and threads (often included);
- soft cloth to remove excess liquid;
- screwdriver;
- tweezers;
- film.

For the lubrication procedure, you cannot use any other oil other than machine oil! First you need to pre-prepare your sewing machine. For this:
- Remove dust from parts of the device, including under the platform.
- Get rid of dirt in the lubrication holes.
- Wipe the outside with a cotton swab soaked in alcohol and petroleum jelly.
Important! If the unit has not been used, it should be stored under a hood or cover.
Let's look at the algorithm for how to lubricate a Janome sewing machine. When working, you must follow the operating instructions.
Step-by-step algorithm:
- Disconnect the device from the power supply and remove the threads.
- Spread the oilcloth on the table and place the typewriter there.
- Unscrew the screws and remove the plastic housing according to the instructions. To avoid confusion when assembling, place them on labeled paper sheets.
- Clean the “backbone” with a brush, removing all dirt.
- Fill a syringe with oil and lubricate all parts and rubbing parts indicated in the attached documentation. Usually there are photographs, so it won’t be difficult to figure it out.
- Blot excess oil with a napkin.
- Assemble the body.
- Thread the sewing machine and sew a few stitches to make sure the seam is clean and free of oil marks.
- The procedure is completed.
Features of the lubrication procedure
A common mistake is to apply as much oil as possible. In fact, this is not true. During operation, dust accumulates inside the device and gets there along with the fabric. For this reason, problems may arise with the advancement of the web. Contamination creates additional stress on the device drive. A large amount of oil applied during care contributes to the accumulation of dust, threads, and fabric scraps. Forming lumps, the mass accumulates in a certain place, which leads to congestion and malfunctions.

There are many articles on the site dedicated to repairing sewing machines. However, first of all, these articles are of an informative nature, intended not for amateur craftsmen, but for owners of sewing machines.
From them you will learn how this or that sewing machine works, what breakdowns are possible if you do not follow the operating instructions. And finally, how to perform a simple repair of a sewing machine with your own hands, if it is not possible to go to a workshop.
In this article you will learn how the Janome sewing machine works. What is the difference between inexpensive models of Janome machines, what kind of breakdowns do they have and whether it is possible to repair it yourself.
1. Janome sewing machine with swinging hook
This model of Janome sewing machine has an oscillating hook type. This shuttle is used only by Janome, but also by other sewing machine manufacturers. These are cars with an entry-level price, which you can buy in the range of 4-5 thousand. They are quite reliable and “hardy”, but there are limits to everything, and after we decided to hem several jeans at once on this particular machine (photo), it ended up in our workshop.
Look at the photo. The arrows indicate the nose of the shuttle and the eye of the needle. You can see that when the nose of the shuttle approaches the needle, the eye of the needle is too high and therefore no stitches are formed. This is a very common "breakdown". In quotes because such a failure occurs when the operating rules of any sewing machine are not followed, and Janome is no exception. This is not even a breakdown, but a violation of the parameters of interaction between the shuttle mechanism and the needle. This happens at a time of excessive load. And doing a finishing stitch on the hem of jeans is just that case. The toothed belt connecting the upper and lower shaft “slips by a tooth” and the machine stops forming stitches, although it still works normally. Probably, jeans are the biggest “enemy” of all sewing machine manufacturers. How much they undermine the image of any of them. After all, it is jeans that most often put household sewing machines out of action.
To understand why this happens and why jeans cannot be hemmed on household sewing machines, count how many layers of fabric are formed at the roughest place (the seam junction). From 9 to 12 layers. Take a needle and try to pierce such an area with a hand needle, it is unlikely to work. Only if you hammer the needle.
But let’s return to our Janome sewing machine and try to figure out how such a failure occurred and whether it can be fixed on our own.
Firstly, it must be said that if the machine stops forming stitches normally, gaps appear, or thread breaks, then look at how the nose of the shuttle interacts with the needle.
Remove the presser foot and needle plate. Lay the machine on its side and remove the upper part of the shuttle stroke so that the shuttle remains in its grooves and is not distorted. Now carefully turn the handwheel and bring the nose of the shuttle to the needle. If you find such a “picture” as in this photo, it means that the cause of the malfunction is elsewhere and there is no need to disassemble the machine. The photo shows that the nose of the shuttle fits, as it should, 1.5-2mm above the eye of the needle. If the spout is lower than the ear or level with it, it means that we will have to disassemble the body of the machine in order to gain access to the unit we need.
I do not recommend disassembling modern sewing machines. There is nothing complicated about this, but only for those who know how to do it correctly. In any other case, the desire to use a nail puller always arises. Well, it seems like all the screws are unscrewed, but the case does not come apart. Be careful, you can easily break not only the housing mount, but also the necessary part of the sewing machine.
Each machine uses its own options for attaching the body halves. First you need to carefully study them and discover them. For example, several pieces may be located under the front cover, in the area of the upper thread tensioner, the shuttle mechanism (remove the needle plate).
Further, some of them are “hidden” under plugs that can be easily removed with a knife blade. What else can I recommend? Well, for example, for this model Janome does not need to remove the levers for switching stitch types. By the way, don't forget about the reverse lever when you put the body back together. In general, for a non-specialist it will be much more difficult not to disassemble it, but to assemble it, keep this in mind. Mark where and what screw was located. And if you don’t have a single “extra” screw left, then you have passed the attentiveness test by 5 points.
4. Janome sewing machine structure
If you are going to buy an inexpensive Janome sewing machine, you can look at these photos that clearly demonstrate its structure. This will help you make the right choice.
In the next paragraph you will find out the reason for the malfunction of this sewing machine.
If the copier is “dry”, its grooves should be lubricated with thick lubricant.
Check the tension of the electric drive belt. If it is loose, tighten it slightly with the screws that secure the motor to the housing. The belt should not be overtightened; when pressed with a finger, it should bend slightly.
If your machine has “problems” with the tension of the upper thread, most likely the reason is this knot. Raise and lower the presser foot several times and make sure that this lever works correctly. It may need to be adjusted.
Behind the upper thread tensioner there is a housing securing screw. It's easy to unscrew, but not easy to put back. Place the screwdriver on the magnet for half an hour, and then it will be easier to install it.
The tensioner screws should not be unscrewed when removing the housing cover.
The cause of the malfunction was in this node, marked with an arrow. Moreover, this was not discovered immediately. This model of the Janome sewing machine did not have a toothed belt connecting the main shaft to the lower shaft. Instead, a crank mechanism was used. It is quite reliable and can withstand heavy loads, so the search for the cause of the failure was directed in the other direction.
However, it later turned out that while hemming the jeans, the eccentric mounted on the main shaft and transmitting movement to the lower shaft had shifted. As a result, without load, the machine parameters were normal, and no stitching was formed during sewing. The mount for this eccentric is located inside (arrow).
After setting the correct parameters for the interaction of the needle and the nose of the shuttle and then tightening the eccentric fastening (screw), the breakdown was eliminated.
Janome sewing machines have many different models designed for different categories of customers. There are a number of economy-class sewing machines that are affordable and designed for small sewing and repair of clothes at home.

Owners of Janome brand sewing machines know firsthand about the excellent quality of this sewing equipment and have personally seen this from their own experience. Although sometimes you still have to make minor repairs to the Janome sewing machine yourself, which consists of replacing the needle or adjusting some units of the unit for more correct and accurate operation. But not a single type of mechanical equipment, and especially equipment with electronic filling, is insured against wear or complete failure of some spare parts.
Needless to say, if any breakdown occurs in a Janome sewing machine, the most correct solution would be to call a technician to your home or transport the sewing machine to a service center to correctly determine the cause of the breakdown and effectively eliminate it. The subsequent reliability of the functioning of the sewing machine directly depends on professionally carried out repairs and adjustments of the sewing equipment.
Our official service has professionally trained employees and all the necessary modern resources, including tools and original spare parts, to carry out high-quality repairs of Janome sewing machines. A large number of people turned to us for help with repairs and were completely satisfied with the quality of the work performed.

Speed and quality of work related to diagnostics, repair and adjustment of Janome sewing machines;
The service of calling a technician to your home, which allows you to significantly save time and money for our clients, and also not worry about how to deliver the machine to our service center;
Quite low prices for our services, regardless of the complexity of the breakdown or the model of the Janome sewing machine.
The advisability of self-repairing a Janome sewing machine directly depends on the complexity of the breakdown, confidence in accurately diagnosing the cause of the problem, as well as the ability to fix it. For example, if the needle in your sewing machine breaks, then it is quite possible to replace it on your own, but if the sewing equipment begins to work unstable or stops turning on altogether, then it is better not to even try to fix something yourself, since this can completely break it sewing machine, without the possibility of subsequent restoration of functionality.
If, without the proper knowledge and skills, you try to fix an unknown problem yourself, then there is a high probability of further aggravating the breakdown and making its subsequent repair more difficult and expensive. Only a person with experience and sufficient knowledge is able to competently diagnose the cause of the problem and professionally eliminate it. By contacting our service center, you will receive high-quality, qualified assistance in repairing Janome sewing machines from our professionally competent craftsmen.
The famous Japanese brand Janome is famous for the excellent quality of its products. More than 300 models of sewing machines alone are produced. About a hundred countries have existing contracts for the supply of Janome sewing machines.
By this indicator one can judge the quality of manufactured products. Every day, thousands of machines leave the assembly lines of enterprises, and the stable demand for them confirms the amazing manufacturability and functionality of the devices. In addition to ready-made machines, enterprises also produce spare parts for Janome sewing machines, including even .
Like all Japanese technology, sewing machines of this brand are very reliable and of high quality in terms of manufacturing. However, breakdowns happen to them too. The main reasons for them are negligence in performing work and lack of proper care.
Even the best equipment can become unusable if it is not provided with proper operating conditions. Below we will look at typical breakdowns in which repair of Janome sewing machines becomes necessary.
2 Caring for your Janome sewing machine
Any equipment needs maintenance. This fully applies to sewing machines. With constant work, regular preventive maintenance is also required.
If you begin to notice that the machine is starting to malfunction, make noise, skip stitches, stitch unevenly, or give out some other surprises, then this indicates the need for cleaning and subsequent lubrication. It is also possible that the device requires adjustment.
Often you have to adjust the degree of thread tension. In machines of this class (like) such an operation can be performed without difficulty.
If no work is expected in the near future, the machine can be stored. Before doing this, the Janome sewing machine must be cleaned from dust and lubricated.
Any preventative cleaning and lubrication is accompanied by removing the shuttle. After this, using a special brush, all rubbing surfaces are cleaned of lint and fabric residues. Oil is poured into the technological holes. Rubbing parts are also lubricated.
The places to be lubricated are indicated in the instructions for the specific model. It is advisable to lubricate no more than once a month, since excessive lubrication can contribute to the opposite effect. Any remaining grease must be wiped off with a dry cloth.
After this, the shuttle is installed in place and the machine is finally assembled. If such work is beyond your capabilities, and in your locality there is a service center for Janome sewing machines or just repair of sewing machines, then you can turn to them for service. Otherwise, such preventive measures will have to be carried out independently.
The sewing machine can only be stored in heated rooms with normal humidity. It is unacceptable to leave it in the basement, garage or other rooms in the absence of heating.
And don’t forget, if you are using a sewing machine, you also need to diagnose it for malfunctions regularly.
