How To Fix Hook Timing On Brother Sewing Machine


Sewing machines are great tools for quickly and easily producing garments, but just like any other machine, they can have timing issues. If your Brother sewing machine is running as though it is out of time, that means that the hook and bobbin mechanism, or the needle bar, are not in proper synchronization. Fortunately, it is possible for a home service technician to get it back into proper working order. This article will explain the steps needed to fix the hook timing on Brother sewing machines, as well as provide some tips for maintaining your machine over time.

Explaining Hook Timing On Sewing Machines

For a sewing machine to run properly, the hook must be in correct timing with the needle. This means that the hook must move in sync with the needle bar so that the two can work optimally together. This is also known as the stitch formation of the machine. If the hook is out of time, it can cause many problems for the machine, including poor stitch formation, poor bobbin winding, and thread breakage.
When you identify a hook timing problem on a Brother sewing machine, it can be helpful to familiarize yourself with a few terms, such as needle plate, feed dog, hook, needle bar and presser foot. Knowing these terms will help you identify which pieces need to be moved to correct the hook timing.

Adjust the Hook Timing on a Brother Sewing Machine

Once you understand the basic mechanics of the machine, it is time to start adjusting the hook timing. The first step is to unplug the machine and remove the Needle Plate, which is the plate that covers the feed dog. The next step is to locate the Hook and Needle Bar on the machine and adjust their relative positions. On a mechanical machine, the hook may need to be slightly moved forward or backward to get it back in line with the Needle Bar. On a computerized machine, you may need to adjust the timing motor or motor belt, or check for any damaged parts.
Once the hook and needle bar have been adjusted correctly, it is time to reassemble the machine. Start by replacing the needle plate and hook and then reattach the presser foot. Finally, plug the machine back in and make sure the hook is timing correctly with the needle bar by turning it on and running a test stitch.

Tips for Maintaining Hook Timing on a Brother Sewing Machine

In addition to the steps outlined above, there are a few other things you can do to ensure that the hook timing on your Brother sewing machine stays in good working order. The first is to keep the machine clean and well-oiled. This will help ensure that all of the parts are operating smoothly and without any grinding or binding.
You should also make sure that all of the screws and bolts are properly tightened and that all parts are in good working order. This goes for the hook and needle bar, as well as any other parts that could be impacted by hook timing. If you notice any wear or damage, it is best to have it fixed as soon as possible to avoid any further issues.
Finally, make sure to set the hook timing to the factory settings on your Brother sewing machine. This allows you to start from a good baseline and also makes it easier to detect any changes that may occur over time.

Stitch Formation and Feed Dogs

Stitch formation is crucial when it comes to a correctly timed Brother sewing machine. In order to get this aspect correct, the position of the feed dogs should be set so that they are directly underneath the needle. This ensures that when the needle goes down and the hook moves up, the material is carried smoothly along with the needle. Having the feed dogs in the proper position also helps the needle thread form the stitches properly.

Using a Tension Disc To Adjust Hook Timing

Most Brother sewing machines have an adjustable tension disk that can be used to fine-tune the timing of the hook. This disk works by controlling the amount of tension placed on the thread that passes through the tension disks. You can adjust it so that the thread will move more easily through the hole in the tension disk, which will help ensure that the hook and needle are in correct timing.

Making Hook Timing Adjustments on Mechanical versus Computerized Machines

When adjusting the hook timing on a Brother sewing machine, the steps vary depending on whether you have a mechanical or computerized machine. Adjustments on a mechanical machine are typically made by physically moving the hook and needle bar until they are in correct timing. On a computerized machine, adjustments are usually made by adjusting the timing motor or motor belt.

Pins and Loopers

The pins and loopers of a Brother sewing machine are also important for keeping the hook and needle bar in the correct timing. Loopers are the tiny metal loops that act as guides for the thread as it moves through the machine, so it is important to make sure they are in the proper place. Pins are small metal posts that hold the loopers in place, and it is important to adjust them so that the needle passes through the loopers correctly.

Servicing Your Sewing Machine

Servicing your Brother sewing machine regularly is the best way to ensure that your machine remains in peak operating condition. This includes checking the hook and needle bar for proper synchronization and adjusting any parts that may have worn out or become loose over time. Additionally, it is important to keep an eye on the feed dogs, loopers and pins, and periodically adjust them as necessary. In addition to servicing your Brother sewing machine on a regular basis, it is also important to clean your machine regularly and lubricate the moving parts. Doing so will help extend the life of your machine and ensure that the stitch formation is always perfect.

Preventative Maintenance

In order to keep the hook timing of your Brother sewing machine accurate, it is important to practice preventative maintenance. This means regularly inspecting the machine for any parts that may need to be replaced, as well as any loose or worn connections. Additionally, remember to clean out lint and thread that accumulates in and around the machine. Finally, always store your machine in a dry and temperature regulated area. This will ensure that your machine remains in good working order and you can continue to enjoy its smooth operation.

Threads and Tension Settings

The tension settings of your Brother sewing machine also play an important role in the machine’s performance. Be sure to adjust the tension setting each time you switch between different threads or fabric types. Additionally, be sure to check the tension of the bobbin case, as this can have a major impact on the way the machine runs. Finally, make sure to test the tension settings by running a test stitch or two before starting a project.


Fixing the hook timing on a Brother sewing machine is not as complicated as it may first seem. With a bit of knowledge about the machine’s parts and the proper maintenance techniques, you can easily keep your machine running in top condition. By understanding the mechanics of the machine and making sure to service it regularly, you can ensure that the hook timing is always accurate, and you can continue to enjoy the perfect stitch formation.
