How to Fix the Hook Timing on a Sewing Machine

When my wife’s sewing machine was broken I decided to call a sewing machine repair shop but they told me it was going to be $90 just to take a look at it. I’m a cheapskate so I decided to do a little internet research to try to figure out how to fix it myself and, fortunately, as you’ll see below, this was just a fix that required some adjustments – no parts or anything like that.

The Issue

The fix we’ll be doing today applies if the hooking wheel (the circle with the hook on it) isn’t grabbing on to the thread, which is what actually makes the loop. In my case, the hooking wheel was just spinning around the threads. It wasn’t grabbing onto anything so that’s what we’re going to be fixing. I’ve got a somewhat older Singer sewing machine but the same principles apply to all machines, old and new.

Tools Required

Tools for fixing sewing machineWe’re just going to use some basic tools. We’ll need Phillips and flathead screwdrivers, a pair of pliers and some Allen wrenches.

Disassembling the Machine

Here’s the underside of the sewing machine. As you can see, there are a lot of gears and mechanisms and such going on here.

As you turn the handwheel you should see this bushing turning and then it exposes the set screw.

The Drive Shaft Bushing

When you rotate the wheel you that there’s just one set screw in there, but I’ve seen other videos where there are two set screws on this bushing. Either way, you’ll need to loosen them. In my case, I needed a 2.5mm Allen key to do so.

You may just need to try this several times but the goal here is to set the bushing to a point where as you turn the handwheel, the hook in the hooking wheel grabs on to the thread as it passes by.

Trial and Error

You may need to adjust a few times to get it to where it grabs the thread. When the needle is at its lowest point the hook should be passing right by it and then snag it. To test it out, I put the machine partially back together and gave it a try to see if you get a straight stitch. After a few attempts, it worked! So that’s what I learned about fixing the timing of the hooking wheel for a sewing machine. It’s all about making sure the bushing is rotated to the right position on the drive shaft, which is what determines the hook timing.
