DIY Sewing Machine Repair Instructions

By Dr. David Trumble


In 1846, a revolutionary invention transformed the production of clothing and other textile applications. That invention is known as the sewing machine. Endless hours of hand stitching were transformed into hours of ease and creativity.

Mechanical sewing machines today use electric motors instead of human power, but in many ways continue the basic elements of the original. Advances are huge. Some boast over a thousand stitches, monogramming, and embroidery.

Do it yourself Sewing Machine Repair:

Many people believe their machine is a vital household appliance which they cannot do without. It is a creative tool that transforms lives and homes.

Like most machines, it needs periodic maintenance. It will fail to operate as desired if neglected over time. Therefore it is important to learn how to do your own servicing.

Often problems with your machine are the result of user error in threading, adjustments, or materials used. If you find a problem, the first thing you need to do is replace the needle with a new one that matches your fabric and project. Second, rethread the upper thread double checking to make sure your thread seats properly in your tension discs. Third, double check your bobbin.

Clean and oil:

The most expensive sewing machine is the one stored in the closet for months at a time. It may not seem logical, but this machine becomes increasingly expensive the longer it is stored. While in storage, it can do no creative work. While in storage, it collects dust. The oils and other lubricants gradually breakdown. In order to put it back into optimum service, it will require cleaning, oiling, and adjusting. Also protect it from moisture, direct sunlight, and extreme temaperatures.

When you are using your machine, you need to service it every few hours to keep it operating properly.

You can do your own cleaning and oiling. By following these simple steps. First, remove the needle plate. Then remove the bobbin, bobbin carrier, and hook assembly (if front or side loaded). Use a small brush to loosen debris. Use canned air or a compressor to blow away lint and debris. Place one drop of pure clean sewing machine oil on the groove in which the hook moves. This is called the race.

Next you need to clean the area above the needle where you find the needle bar assembly, presser bar, and upper tension. Use brush, forced air, or probe as needed to remove all debris. Once clean, oil all the metal to metal contacts with a single drop of oil. Use only pure clean oil. Repeat this process at least once a week.

Periodically, a more extensive cleaning is needed to maintain optimum function. This is commonly referred to a a tune up, full service, or a clean oil and adjust. Many users prefer to have a skilled technician perform this service, however, in most cases you can do this yourself.

The tune up or full service is often performed by a skilled technician by following a long checklist of disassembly, cleaning, lubricating, adjusting, parts replacement, reassembly, and testing. Complete training to help you do this yourself is available.

The assistance of a trained professional or technical support through a training program may be very helpful when undertaking more advanced repairs. Often replacing parts can be a challenge if proper procedures are not followed. Gear replacement, drive shaft replacement, cams and hook assembly issues are among the more challenging repairs that may be required from time to time.

You can keep your equipment operating in good condition year after year. This will save money, time, and frustration. Even more, you can learn to do more advanced repairs for fun or even as a business.
