Need a blow up diagram of the timing parts for Shark Intelli-Sew Euro-Pro Model 9110.
I had a timing problem, I believe, and fixed it. But its not yet perfect.....What happened was the top thread was not being caught by the bobbin holder. So when I "sewed", there were no stitches. When I watched the bobbin through the window, the bobbin didnt turn, and thread didnt whiz around the bobbin holder as it should with each stitch. I even made a video to see if there was a timing problem...the needle went down well before the bobbin holder "thread catcher hook" arrived to catch the loop. So I took off the plate underneath the bobbin holder, and adjusted the timing. When you do that you will see a cogwheel that rotates as the bobbin holder rotates. Three alan wrench screws hold it tight to the axle that rotates with the handwheel/footplate. I loosened the alan wrench screws, and then did the following. Hold the needle holder so it doesnt move, and at the same time turn the hand wheel a little. This adjusts the timing of the needle relative to the bobbin turning. then plug the machine in, and see if the bobbin wheel is now catching the thread. Keep adjusting until it does. Then tighten things back up, and VOILA! Im not sure this is the best way to adjust the timing, but it works. My machine went from no stitches at all, to sewing nicely. Its not yet perfect, as it jams every now and then. But that may be because the timing is still a little off, or because the thread is bad, or the tension of the thread is not quite right......working on that still.......
