Uwe Report post Posted December 21, 2015 After fussing with the safety clutch on my Singer 111W155 for two days to get it to work properly, I decided to make a video to share some of the things I learned in the process. I have three similar machines, the Singer 111W155, a Consew 255, and a Tacsew T1563 (which is a Juki 563 clone) All these have similar safety clutches, but they are different in some aspects. Both Juki and Consew are adjustable in how much force it takes to trip the clutch. The Singer 111W155 safety clutch (at least the one I have) is not adjustable and mine takes a LOT of force to trigger it. I thought it was totally seized up but it really just takes a lot of force to trigger. I had removed the Singer safety clutch to clean it properly (overnight oil bath, three rounds in the ultrasonic cleaning spa.) I still could not trigger it inside the machine, but it does trip if I use a pair of pliers. So it works properly, it just takes a lot of force. Remember, don't mess with your timing belt unless you have to. Mine was flexible enough to slide off the cog wheel - yours may not. Don't force it and don't call me if you rip, tear or otherwise ruin your timing belt. Installing a new timing belt is a major pain from what I've heard and I haven't even done it yet. In any case, here's the video on safety clutches: Quote Share this post Link to post Share on other sites
