Adjust Sewing Machine Timing
Your sewing machine’s timing is essential to achieving even stitches in your fabric and ensuring that the machine’s parts are working in sync. Although the general process for adjusting timing is the same for most sewing machines, the method of removing, modifying and installing parts is different for each machine, so consult the owner’s manual of your machine as you go through the stages of checking and fine tuning the timing on your machine.
By testing the alignment of the needle and the shuttle hook, you can determine whether your machine needs a timing adjustment. Use a ruler to measure the timing settings. Use the hand wheel to put the needle in the lowest position, then raise it 3/32 of an inch. The shuttle hook should meet the needle just above the eye while it is in this position. If it does not, you may need to adjust the timing. Most machines have marks on them that indicate the appropriate height for the needlebar. Consult your manual for specifics on how to access and loosen your needle bar. If timing marks are present, loosen the needlebar and slide it up or down to align the top timing mark just below the bottom of the timing bar bushing.
If timing marks are not present, lower the needle completely with the hand wheel, then raise it 3/32 of an inch (2.4mm). Adjust the needle’s height so that the needle eye is 3/32 of an inch below the point of the hook. Adjusting the hook timing varies between manufacturers and models. The general approach, however, is to adjust the distance between the hook and the needle.
